Virtual Machine Files Type

When you browse a VM folder on a datastore you find different types of files listed there . Each file has specific role in a VM functioning. We will learn here for which purpose which files are created. Typically you will find following types of files in a VM directory:

VMDK files – VMDK files names as (VMware Virtual Disk file) are the actual virtual hard drive for the virtual guest operation system. You can create dynamic or fixed virtual disks. With dynamic disks, the disks start small and grow as the disk inside the guest OS grows. With fixed disks, the virtual disk started out at the same (large) disk size decided initially while creating VM.

Log files – Log files are just that- a log of VM server activity for a single virtual server. Log files can be used only while doing any troubleshooting with a virtual machine. It can be more than 1 or 2 and modified each time while we Start, Suspend or reboot the Virtual Machine. 

VMX files – a VMX file is the primary configuration file for a virtual machine. When you create a new virtual machine and answer questions about the operating system, disk sizes, and networking, those answers are stored in this file. As you can see from the screenshot below, a VMX file is actually a simple text file that can be edited with Notepad.

VMEM – A VMEM file is a backup of the virtual machine’s paging file. It will only appear if the virtual machine is running, or if it has crashed.

VMSN files – these files are used for snapshots. A VMSN file is used to store the exact state of the virtual machine when the snapshot was taken. Using this snapshot, you can then restore your machine to the previous state as when the snapshot was taken.

VMSD files — A VMSD file stores information about snapshots metadata. You’ll notice that the names of these files match the names of the snapshots.

NVRAM files – These files are the BIOS for the virtual machine. The VM must know how many hard drives it has and other common BIOS settings. The NVRAM file is where that BIOS information is stored.

VMSS files – A VMSS file is VMware Suspended virtual machine state and it is created while you suspend any Virtual machine. It stores the information of the running application while suspending the machine.

VMXF Files – A VMXF file is VMware team member file which is created during creation of Virtual machine and its shows the information about the client MetaData Attributes & VMID.

How to install Spacewalk Server on Centos 6

Spacewalk is an open source Linux systems management solution. Spacewalk is the upstream community project from which the Red Hat Satellite product is derived.

Spacewalk manages software content updates for Red Hat derived distributions such as Fedora, CentOS, and Scientific Linux, within your firewall. You can stage software content through different environments, managing the deployment of updates to systems and allowing you to view at which update level any given system is at across your deployment. A central web interface allows viewing of systems, their associated software update status, and initiating update actions.

Additional Management Capabilities

Spacewalk provides provisioning and monitoring capabilities, allowing you to manage your systems throughout their lifecycle. Via Provisioning, Spacewalk enables you to kickstart provision systems and manage and deploy configuration files. The monitoring feature allows you to view the status off your systems alongside their software update status. Spacewalk also has virtualization capabilities to enable you to provision, control, manage, and monitor virtual KVM and Xen guests.

The supported database options are Postgres and Oracl, so in this case we are using Postgres. Follow the steps shown below to install Spacewalk Server on Centos 6

Download the spacewalk repo

[root@server]# wget http://spacewalk.redhat.com/yum/latest/RHEL/6/x86_64/spacewalk-repo-1.9-1.el6.noarch.rpm

Install the spacewalk repo

[root@server]# rpm –ivh spacewalk-repo-1.9-1.el6.noarch.rpm

Install the yum priorities plugin

[root@server ]# yum install yum-plugin-priorities

Install the rest of the required repo’s

[root@server]# rpm -Uvh http://mirrors.dotsrc.org/jpackage/5.0/generic/free/RPMS/jpackage-release-5-4.jpp5.noarch.rpm

[root@server]# rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

[root@server]# rpm -Uvh http://epel.mirror.net.in/epel/6/x86_64/epel-release-6-8.noarch.rpm

[root@server~]# rpm –ivh http://spacewalk.redhat.com/yum/1.7-client/RHEL/6/x86_64/spacewalk-client-repo-1.7-5.el6.noarch.rpm

Next you need to make a change to the jpackage repo

[root@server]# vim /etc/yum.repos.d/jpackage.repo

Look for the following section at the bottom

[jpackage-distro]

name=JPackage (free) for distro $releasever

mirrorlist=http://www.jpackage.org/mirrorlist.php?dist=redhat-el-$releasever&type=free&release=5.0

failovermethod=priority

gpgcheck=0

enabled=1

priority=10

You need to change the mirrorlist line so it looks like the following. The difference is the $releasever has been changed to 5.0

[jpackage-distro]

name=JPackage (free) for distro $releasever

mirrorlist=http://www.jpackage.org/mirrorlist.php?dist=redhat-el-5.0&type=free&release=5.0

failovermethod=priority

gpgcheck=0

enabled=1

priority=10

Next Step is to Cleanup  YUM

[root@server]# yum clean all

Next install Postgres, set it to run on boot and run the initial configuration

[root@server~]# yum install postgresql postgresql-contrib postgresql-devel postgresql-server

[root@server~]# chkconfig postgresql on

[root@server~]# service postgresql initdb

[root@server~]# service postgresql start

 Create the database and user for Spacewalk

[root@server~]# su – postgres -c ‘PGPASSWORD=spacepw; createdb spacedb ; createlang plpgsql spacedb ; yes $PGPASSWORD | createuser -P -sDR spaceuser’

Now you need to configure the user to use an md5 password

[root@server~]# vim /var/lib/pgsql/data/pg_hba.conf

At the bottom of the config file you will see to following lines

# “local” is for Unix domain socket connections only

local                 all         all                                            ident

# IPv4 local connections:

host                 all         all         127.0.0.1/32               ident

# IPv6 local connections:

host                 all         all         ::1/128                        ident

Before those lines add the following:

local     spacedb           spaceuser         md5

host     spacedb           spaceuser         127.0.0.1/8      md5

host     spacedb           spaceuser         ::1/128             md5

local     spacedb           postgres           ident

Reload Postgres for the changes to take effect

[root@server~]# service postgresql reload

Now install Spacewalk. It will take some time on a minimal install it had to install over 400 dependencies.

[root@server~]# yum install spacewalk-postgresql

[root@server~]#  yum install spacewalk-setup-embedded-postgresql

Once it is installed run the Spacewalk setup

[root@server~]# spacewalk-setup –disconnected

You will first be prompted for the database information. Leave the location blank, the database is spacedb, the username is spaceuser and the password is spacepw

** Database: Setting up database connection for PostgreSQL backend.

Hostname (leave empty for local)?

Database? spacedb

Username? spaceuser

Password? spacepw

The rest you can use the defaults. The final step will be generating a SSL certificate, just enter your details as required

Access the web interface by going to https://IPADDRESS you will be prompted to create a user. Once done you are ready to start connecting client machines.

How to walk with spacewalk

Populate Spacewalk

The goal is to deploy a new machine with an os, this means the obvious next step is to populate spacewalk with a Red Hat derived Linux distribution of your choice.

First step is to mount the CentOS 6.1 iso’s somewhere on your spacewalk server. Make sure to get a full distro iso, this means that required directories like, for example, images/pxeboot do exist. The packages which belong to a distribution are administered in Spacewalk as software channels, so we first have to create a software channel before we can add/upload packages to it.

Create a new software channel by opening the spacewalk console and navigate to:

“Channels” -> “Manage Software Channels” -> “Create New Channel”

Enter a reasonable channel name (this is for display only, e.g: “CentOS 6.1 – 64 Bit”), a channel label (remember this name for later use,e.g: “centos6.1-x86_64″) and select the correct architecture (x86_64).

Next step is to populate spacewalk with the CentOS packages, this proces is started by issuing the following command:

rhnpush -v –channel=centos6.1-x86_64 –server=http://localhost –dir=/path/to/Packages

where “/path/to/Packages” is the absolute path of the Packages directory of the mounted iso.

CentOS 6.1 consists of two dvd’s, execute above step for both dvd’s.

The rhnpush process uploads all packages and registers them in spacewalk. On average, rhnpush processes packages at a rate of around 2000 packages per 30 minutes (ofcourse depending on the configuration of your host and vm). CentOS 6.1 contains almost 6200 packages so, it will take around one and a half hour to upload all packages from dvd1 and dvd2 to spacewalk.

The deployed linux system should to be able to connect to the spacewalk server and use it’s package and configuration management facilities it is recommended to include the spacewalk client packages in a spacewalk channel as well. Now we will upload the packages directly from the online repository into a child channel of the just created CentOS channel.

In the spacewalk console navigate to:

“Channels” -> “Manage Software Channels” -> “Create New Channel”

Enter a reasonable channel name ( e.g. : “Spacewalk Client 1.5 – el6 – 64 Bit”), a channel label (e.g.  “swclnt1.5-el6-x86_64″), the correct architecture (x86_64) and the correct parent channel (e.g. : “CentOS 6.1 – 64 Bit”).

Populating spacewalk with the spacewalk client packages directly from the online repository is started by issuing the following command:

spacewalk-repo-sync -c swclnt1.5-el6-x86_64 –url http://spacewalk.redhat.com/yum/1.5-client/RHEL/6/x86_64

The spacewalk client has a dependency on the python-hwdata-1.2-1.el6.noarch.rpm package from the epel repository. Download the python-hwdata-1.2-1.el6.noarch.rpm package from the epel repositor http://download.fedora.redhat.com/pub/epel/6/x86_64/

and upload it to the spacewalk client child channel using the command (assuming you downloaded the rpm to a folder named epel):

rhnpush -v –channel=swclnt1.5-el6-x86_64 –server=http://localhost -dir=epel

Create a distribution

For automating the installation of a Linux system a method called kickstart can be used. First, we have to setup a directory structure on the spacewalk server based on content of the CentOS dvd1 iso. From your CentOS 6.1 dvd1, copy the following directories:

  • images
  • isolinux
  • repodata

to:
/var/distro-trees/centos6.1-x86_64

Next, open the spacewalk console and navigate to the following location:

systems -> kickstart -> distributions -> new distribution

Enter the following parameters for the new distribution:

  • Distribution label: centos6.1-x86_64
  • tree path: /var/distro-trees/centos6.1-x86_64
  • Base Channel: CentOS 6.1 – 64 Bit
  • Installer Generation: Red Hat Enterprise Linux 6

Next step is to create a kickstart profile for the channel and distribution. Open the spacewalk console and navigate to the following location:

systems -> kickstart -> create new kickstart profile

Enter the following parameters for the new kickstart profile:

  • Label: centos61-minimal
  • Base channel: CentOS 6.1 – 64 Bit
  • Kickstartable tree: centos6.1-x86_64
  • Virtualization type: none

To make sure the spacewalk client repository is used during kickstart, navigate to the following location:

systems -> kickstart -> profiles -> centos61-minimal -> operating system

Make sure the child channel swclnt1.5-el6-x86_64 is checked.

Also, have a look at the other tabs to have an idea of the configuration options which are available. Possible interesting area’s are:

  • Software: Adding extra packages or package groups in addition to the base installation. Add the package just by adding it on a new line, package groups can be added by an @-sign followed by the group name. A package can be excluded by an hyphen (-) followed by the package name
  • Kickstart details -> Details -> Kernel options: Adding and removing kernel options. You can add a kernel option, just by adding it’s key/value pair to the input field. Removal is done by just mentioning the kernel option preceded by an ! and giving it ~ as a value. For example, the value “!text=~ resolution=800×600″ in the kernel option box forces the use of the graphical installer (remove the text kernel option) and sets screen resolution to 800×600.
  • Kickstart details -> Advanced options: Allows detailed configuration of the kickstarted system. For example, to add an user,during installation, named weblogic with password weblogic01, tick the “user” checkbox and add the value “–name=weblogic –password=weblogic01 –plaintext” to the input field.
  • Kickstart details -> Variables: the usage of variables can be done by adding a key/value pair and refer to it in another tab. For example , to define the hostname during kickstart, add a key/value pair (hostname=appsrvr1) in the variables tab and refer to it in the Advanced options by adding “–hostname $hostname” to the network text box.

Let’s cobbler

Next step is to create an iso image to boot a new vm from.

Important note: In the next couple of steps we are going to deploy a new linux virtual machine. If the virtualization network setup supports a dns where the spacewalk server can be found by its hostname skip the next step.

In other words, your newly created vm must be able to find the spacewalk server using it’s hostname during boot/initial setup. If this is not the case or if you are unsure, please perform the following step to change the spacewalk hostname to its ip-address, if you are sure dns is in place you can skip this step:

In /etc/rhn/rhn.conf change the value of the parameter cobbler.host to the ip address of the spacewalk server.
In /etc/cobbler/settings change the value of the parameters server and redhat_management_server  to the ip-address of the spacewalk server.

On the spacewalk server, run the command (this only needs to be done once):

cobbler get-loaders

Next, start building the iso using the command:

cobbler buildiso

The result of the buildiso command is a file named generated.iso in the directory from where you issued the command.

Let’s kickstart

On your host, create a new virtual machine and provide it with the generated.iso file to boot from. Upon boot you will see a menu as shown below allowing you to specify the centos61-minimal setup to be installed.

spacewalk

Installation will take some time. After installation is finished we will configure this client to talk with spacewalk server.

Configuring spacewalk client

The following instructions are for configuring a Centos 6 box to talk to a Spacewalk server

Install the Spacewalk Client repo

[root@client~]# rpm -Uvh http://spacewalk.redhat.com/yum/1.7/RHEL/6/i386/spacewalk-client-repo-1.7-5.el6.noarch.rpm

Clean all the yum repos

[root@client~]# yum clean all

Install the required packages

[root@client~]# yum install rhn-client-tools rhn-check rhn-setup rhnsd m2crypto yum-rhn-plugin

Now you need to generate a activation key. The steps to do this are:

  1. Log into the Spacewalk web interface
  2. From the top navigation select Systems
  3. In the left navigation select Activation Keys
  4. In the top right hand corner click New Key
  5. Enter a name for this activation key and click Create Activation Key
  6. The activation key will then populate

On the client run the configuration tool. Replace the IP and activation key with those from your setup. Once done your computer will be visible in the list of systems in spacewalk.

[root@client~]# rhnreg_ks –serverUrl=http://x.x.x.x/XMLRPC –activationkey=1-414ace93e6c3e94c85aec54a653e761d

Note: x.x.x.x is your spacewalk server IP address

Collecting Horizon View logs with PowerShell script

If you are facing any issues in Horizon View environment and need to do troubleshooting it’s a very difficult task to cycle throughout all component logs. Also it’s a bit difficult to remember the location of every log file is across the different components.

I found a PowerShell script on internet which can ease your paint of collecting the log files for Horizon View environment.

This powershell script is written by VMware Architect Markt Ewert. This script automates the log files collection, including Connection Servers, Security Gateways, Desktops, View Composer and Transfer Servers.

Troubleshooting common P2V Conversion Failures

Conversions sometimes fail no matter how careful you are preparing the server. The failure can occur at various stages in the conversion process; these stages are based on the task bar percent and are estimated values.

1.      Creation of the target virtual machine (VM) (0%-5%)
2.      Preparing to Clone the Disk (5%-6%)
3.      Cloning (6%-95%)
4.      Post-cloning (95%-97%)
5.      Customization/Reconfig (97%-99%)
6.      Install Tools/Power On (99%-100%)

The conversion process may fail at any stage, but if it’s going to fail, it will typically fail at 97%. Converter creates a detailed log file during the conversion process which will contain exact errors pertaining to why the conversion failed.

This log file is located on the server you are converting that is running the Converter agent, and is usually named vmware-converter-0.log and is located in the C:\Windows\temp\vmware-temp directory. Open this log file and scroll towards the bottom and look for failure errors. Once the process fails, Converter will destroy the VM that it created automatically.

One clue to determine which stage it failed at is how fast it gets to 97%. If it jumps to 97% quickly and fails, this usually indicates a problem with network ports, DNS resolution or a required Windows service that is not running. Here are some things to try to resolve these types of problems.

1.      If you used a hostname to choose your VC/ESX server destination make sure you can resolve it on your source server. Also try using the FQDN of the server instead of the short name.

2. On the source server make sure the Workstation, Server, TCP/IP NetBIOS Helper and VMware Converter services are running. On Windows XP and 2003 servers make sure the Volume Shadow Copy service is not disabled, by default it should be set to Manual. This service does not need to be running for Converter to work.

3. Use telnet to see if you can connect to the required ports on the VC/ESX servers. From the source server type “telnet 902”. You should get a response back from the VC/ESX server, also do this on port 443.

4. Try rebooting the source server, this is a requirement for Windows NT and 2000 servers.

If it takes a long time to get to 97%, then typically the clone failed during the data cloning process or the post-cloning procedures. Some possible causes of these types of failures can be lost network connectivity between the servers, excessive network errors and source disk problems. Here are some steps to try to resolve these types of problems.

1.  Verify network speed/duplex settings match on your source server’s NIC and the physical switch port it is connected to.

2.  If you have OS mirroring enabled, break the mirrors.

3.      Clean-up your boot.ini file and make sure it is correct.

4.      Make sure you are using the latest version of Converter. Earlier versions fail if the source server has dynamic disks.

5.      Run chkdsk on your source server to verify file system integrity.

6.      Ensure you have at least 200 MB of free disk on the source server.

7.      If your source server has more then two serial (COM) ports, edit the registry and look for HKLM\HARDWARE\DEVICEMAP\SERIALCOM and remove any ports above serial port 2. You can export the key before you do this and re-import after the conversion is completed if needed.

Finally, if your conversion completes successfully but your server will not boot (or boots to a blue screen) you can try the following things to fix it.

1. Edit the boot.ini on the newly created VM to make sure the disks are in the proper order. Sometimes the boot disk will not be listed as the first partition. To do this, simply use a working VM as a helper and add an additional virtual hard disk. Browse to the newly created VM’s disk file.

You can then browse that disk and edit the boot.ini file. When complete, remove the disk from the helper VM. You can also try running Converter again and selecting “Configure Machine” and select your newly created VM. Run through the Wizard, and (when complete) try powering it on again.

2.  Verify you are using the proper SCSI controller for your virtual disk (BusLogic or LSI Logic).

3.  Boot the VM in safe mode to see if any hardware specific services/drivers are loading.

Enhancing performance in a new virtual machine

When your conversion completes, there are several steps you should to do clean your new VM up so it will perform better.

1. Edit the VM’s hardware. Remove all unnecessary hardware, including floppy drives and serial, parallel and USB ports. You should only give the VM as much RAM as it needs. Reduce it if you can. Most VM’s run better with one vCPU, so consider reducing the number of CPUs if you came from a SMP physical server.

2. Power on the VM, wait a few minutes to let it discover all it’s new hardware then reboot it.

3. Check the server HAL, if you came from a multiple CPU physical system and have a single CPU VM you need to go into Device Manager and edit the CPU (Computer). Select Update Driver, say No to Windows Update, select Install from List, select Don’t Search and select ACPI Uniprocessor instead of ACPI Multiprocessor.

4.      Remove any hardware specific applications and drivers.

5.      Finally, my most important tip: Remove all non-present hardware devices. These are hardware devices that were removed from the system without having been uninstalled and are a by-product of the conversion.

These devices are not physically present in the system any more, but Windows treats them as they were there and devotes system resources to them. They can also cause conflicts when trying to set your new network adapter’s IP address to the same address of the source server. The reason for this is that the old NIC still exists as non-present hardware with an IP address. There will be dozens of non-present hardware devices left after the conversion.

To remove them all simply go to a CMD prompt and type SET DEVMGR_SHOW_NONPRESENT_DEVICES=1.

Then in the same CMD window type DEVMGMT.MSC and then select Show Hidden Devices when the Device Manager window opens.

As you expand each hardware category you will see lots of non-present devices, indicated by grayed out icons. Right-click on each and select uninstall. Reboot once you have removed them all.

How to reset MySql Root password in Windows

Resetting the Root Password: Windows Systems
On Windows, use the following procedure to reset the password for all MySQL root accounts:
1. Log on to your system as Administrator.

2. Stop the MySQL server if it is running. For a server that is running as a Windows service, go to the Services manager: From the Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list and stop it.
If your server is not running as a service, you may need to use the Task Manager to force it
to stop.

3. Create a text file containing the following statements. Replace the password with the
password that you want to use.

UPDATE mysql.user SET Password=PASSWORD(‘MyNewPass’) WHERE User=’root’;
FLUSH PRIVILEGES;

Write the UPDATE and FLUSH statements each on a single line. The UPDATE statement
resets the password for all root accounts, and the FLUSH statement tells the server to reload the grant tables into memory so that it notices the password change.

4. Save the file. For this example, the file will be named C:\mysql-init.txt.

5. Open a console window to get to the command prompt: From the Start menu, select Run, then enter cmd as the command to be run.

6. Start the MySQL server with the special –init-file option (notice that the backslash in the option value is doubled):

C:\> C:\mysql\bin\mysqld-nt –init-file=C:\\mysql-init.txt

If you installed MySQL to a location other than C:\mysql, adjust the command accordingly.

The server executes the contents of the file named by the –init-file option at startup,
changing each root account password.

You can also add the –console option to the command if you want server output to appear in the console window rather than in a log file.

If you installed MySQL using the MySQL Installation Wizard, you may need to specify a —
defaults-file option:

C:\> “C:\Program Files\MySQL\MySQL Server 5.0\bin\mysqld-nt.exe”
–defaults-file=”C:\\Program Files\\MySQL\\MySQL Server 5.0\\my.ini”
–init-file=C:\\mysql-init.txt

The appropriate –defaults-file setting can be found using the Services Manager: From the
Start menu, select Control Panel, then Administrative Tools, then Services. Find the MySQL service in the list, right-click it, and choose the Properties option. The Path to executable
field contains the –defaults-file setting.

7. After the server has started successfully, delete C:\mysql-init.txt.

You should now be able to connect to the MySQL server as root using the new password.

Stop the MySQL server, then restart it in normal mode again. If you run the server as a service, start it from the Windows Services window. If you start the server manually, use whatever command you normally use.

cannot remediate host because it is part of HA Admission Control enabled Cluster

Problem:

Sometimes you will face an error while patching your esxi servers using VMware Update Manager(VUM). When you try to remediate your esxi host you get the error message:

“The operation is not supported on the selected inventory objects. Check the events for the objects selected for the operation”

Further when you check the event logs you will find following entry:

“cannot remediate host because it is part of HA Admission Control enabled Cluster”

You can also check logs on your VUM server.The log file is vmware-vum-server-log4cpp.log and is located at :

C:\Documents and Settings\All Users\Application Data\VMware\Update Manager

or

C:\Users\All Users\VMware\VMware Update Manager\Logs

you see an error similar to:

“[DATE’VciHostRemediateTask.VciHostRemediateTask{14}’ 2276 INFO]  [vciHostRemediateTask, 1313] Skipping [HostName] as it is part of HAC enabled cluster”

Cause:

This issue occurs because the admission control policy that has been set is preventing Update Manager from remediating the host.

vCenter Server uses admission control to ensure that sufficient resources are available in a cluster to provide failover protection and to ensure that virtual machine resource reservations are respected.

Admission control imposes constraints on resource usage and any action that would violate these constraints is not permitted. If an automated process needs to take actions, it might temporarily violate the failover constraints. For example, as part of an upgrade directed by VMware Update Manager.

Solution:

Before starting patching of your Esxi Servers that are part of the HA Cluster, make sure you disable “Admission Control” till the time when patching and rebooting of Esxi servers are completed.Once you patched all the servers you can re-enable Admission Control on your cluster.

Steps to disable Admission Control”

1: Right-click the cluster and click Edit Settings.

2: Under Cluster Features, click VMware HA.

3: Under Admission Control, select Disable: Power on VMs that violate availability constraints.

4: Click OK.

How to restrict Vmware Converter from using SSL to speedup conversion process

A protocol called NFC is used by VMware Converter for the cloning process.

In VMware Converter 5.0 encryption was introduced to increase security for the data transfer but at the expense of performance.

To improve the performance of the converter we can disable this feature.

To do so we need to edit the converter-worker xml file. The default location of this file is

“C:\Users\All Users\Application Data\Application Data\Application Data\VMware\VMware vCenter Converter Standalone\converter-worker.xml”

Open this file and go to the locate the section which contains

<nfc>

            <readTimeoutMS>120000</readTimeoutMS>

            <useSsl>true</useSsl>

</nfc>

Change the value of useSsl from true to false.

After this restart the vmware converter services from services.msc.

Relatively far down you will find the parameter for “nfc” – change the value in “useSsl” from “true” to “false”:

122 VMJuggler: The program is quite simple, it connects to VirtualCenter 2.x and you can select a VM and 2 hosts. After selecting this you can start the juggler and the VM will be moves every 10 seconds between the hosts.

124 Virtual MAC Tools: The tool was originally developed because of the way we manage IP addresses of our servers – every server (physical and virtual) is configured for DHCP and has a fixed reservation for its MAC address. So we require MAC addresses on our VMs that won’t change. I wrote this little app to make it easier and faster to do this, instead of having to SSH into the host and edit .vmx files by hand, and hope that VirtualCenter doesn’t want to overwrite your changes. Since then it’s been easier for me to add extra little features than write separate apps for everything – so now it also has a basic reporting feature. Overall, the application is very simple. It was designed and built in VB.NET 2005, and uses the VI3 SDK. There is limited error-handling in a few places, but in most cases it will probably just crash. It should be quite safe to use though – all it knows how to do is submit a VM_Reconfigure task with a modified virtual network device – it won’t delete VM’s or anything dangerous. There is no support offered with this tool. Download
125 VM Time: A small utility that measures the time within a Virtual Machine and the time of the Host it is running on. It will report on any time differences between the two. Nice for testing and checking if the VM really knows what time it is and detect any ‘time drifting Download

How to Install and configure vSphere Data Protection

vSphere Data Protection

vSphere Data Protection is a new backup and recovery solution designed for VMware vSphere. It provides advanced deduplication and is included with vSphere 5.1. vSphere Data Protection is powered by EMC Avamar, leveraging years of backup and data recovery expertise and production-proven quality and performance. vSphere Data Protection provides easy setup and management, deduplication, and high-performance virtual machine image-level backup and recovery.

It is ideally suited to protect smaller environments of up to 2 TB or 100 virtual machines. Larger environments can be protected by scaling out multiple vSphere Data Protection appliances or by deploying vSphere Data Protection Advanced.

I am sharing a video on how to install and configure vSphere data protection virtual appliance:

After completing the installation of VDP Virtual appliance it’s time to configure it.

For login into VDP, point your browser to http://<IP-DAddress&gt;:8543/vdp-configure/

Follow the steps mentioned below to solve the issue:

– Shutdown the VM

– Right click the VM and select Remove from Inventory.

– Go to the Datastore Browser and browse to VM folder which you just removed.  Right-click the .vmx file and select Add to Inventory.

That’s it. Now when you try to edit the settings of VM that error will not bother you.

Vmware Certification Roadmap

There are multiple path in the VMware certification and its based on the product it allows us to choose a product and allow to get certified in the master level. Currently vmware have the certification for the below platforms

Cloud – This is Certification is for the vCloud Products

Data Center Virtualization – This is for the vSphere suite and its the standard certification which is there for long time

End user Computing – This is for the desktop products (View, Horizon)

Now lets see about the different levels of certification on the about the platform

VMware Certified Associate (VCA) – This is new certification program launched by VMware and there is no mandatory training required for this certification. This is for the entry level people who are looking to start their carrier in the VMware technologies. This certification can be registered online and the exam can be taken from home. The Associate exam is available for the below platforms

VMware Certified Professional (VCP) – This certification is there for a long time now and you need to attend a mandatory training from a authorized VATC to sit for this exam. One has to have some hands on experience on the product before sitting for the exam. The VCP certification is available on DCV, Cloud and EUC.

VMware Certified Advanced Professional (VCAP) – This is the advanced certification of the VCP and once has to be a VCP and need to required for authorization from VMware before registering for this exam. And in VCAP we have two exams DCA and DCD. The

Data Center Administration (DCA) exam is a 4 hr lab based exam on the day to day vSphere Administration task and Data Center Design (DCD) is objective and visio based exam from vSphere design perceptive. the VCAP is a per-requisite for
the VCDX exam.

VMware Certified Design Expert (VCDX) – This is the highest level of the certification from the VMware and one has to spend considerable amount of time for VCDX preparation. One has to be a VCP and VCAP certified before they can actually submit the application for the VCDX .

There are total of 15 different exams which one can take in Vmware and is described as follows:
VMware Certified Associate – Data Center Virtualization (VCA-DCV)

Hardening of SSH server

Openssh options are controlled through the /etc/ssh/sshd_config file. This article explains the 7 default options in sshd_config file that you should change to harden your ssh server.

Options that uses the default values contains a commented line with the option and its default value. This makes it easier for us, as we can see the Openssh option name and the default value without having to lookup somewhere else.

For example, sshd_config file contains the following commented line. This indicates that the PubkeyAuthentication option contains “yes” as the default value.

$ grep -i pubkey /etc/ssh/sshd_config

#PubkeyAuthentication yes

If you like to change this, you should remove the comment and change the value (from yes to no)

$ vi /etc/ssh/sshd_config

PubkeyAuthentication no

1. Disable Root Login (PermitRootLogin)

By default you can ssh to the server as root. It is best not to allow root to login directly to the server. Instead, you should login to the system as your account and then do ‘su -’ to login as root.

If you have multiple sysadmins in your organization, and if they all login to the server directly as root, you might not know which sysadmin logged in as root. Instead, if you disable login as root, sysadmins are forced to login as their account first, before they can do ‘su -’, this makes the auditing easier.

Add the following entry to sshd_config to disable root to login to the server directly.

$ vi /etc/ssh/sshd_config

PermitRootLogin no

2. Allow Only Specific Users or Groups (AllowUsers AllowGroups)

By default anybody who is authenticated successfully are allowed to login. Instead you can restrict which users (or groups) you allow to login to the system.

This is helpful when you have created several user accounts on the system, but want only few of them to login.

This is also helpful when you are using NIS, openLDAP (or some other external system) for authentication. Every user in your company might have account on NIS, OpenLDAP etc. But, on a specific server you want only few of them to login. For example, on production system you want only sysadmins to login.

Add the following entry to the sshd_config file to allow only specific users to login to the system. In the example below only ramesh, john and jason can login to this system. Usernames should be separated by space.

$ vi /etc/ssh/sshd_config

AllowUsers ramesh john jason

Add the following entry to the sshd_config file to allow only the users who belong to a specific group to login. In the exampe below only users who belong to sysadmin and dba group can login to the system.

$ vi /etc/ssh/sshd_config

AllowGroups sysadmin dba

3. Deny Specific Users or Groups

Instead of allowing specific users (or groups), you can also deny specific users or groups.

Add the following entry to the sshd_config file to deny specific users to login to the system. In the example below cvs, apache, jane cannot login to this system. Usernames should be separated by space.

$ vi /etc/ssh/sshd_config

DenyUsers cvs apache jane

Add the following entry to the sshd_config file to deny users who belong to a specific group to login. In the exampe below users who belong to developers and qa group cannot login to the system.

$ vi /etc/ssh/sshd_config

DenyGroups developers qa

Note: You can use combination of all the Allow and Deny directivies. It is processed in this order: DenyUsers, AllowUsers, DenyGroups, and finally AllowGroups

 4. Change SSHD Port Number (Port)

By default ssh runs on port 22. Most of the attackers will check if a server is open on port 22, and will randomly use brute force to login to the server using several username and password combination.

If you change the port # to something different, others need to know exactly what port to use to login to the server using ssh. The example below uses port 222 for ssh.

$ vi /etc/ssh/sshd_config

Port 222

From your logs (/var/log/secure), if you see lot of invalid logins using ssh for accounts that don’t exist on your system, from the ip-address that you don’t recognize, it might be some brute-force attack. Those kind of ssh invalid login will stop, if you change the port number.

Please note that this causes little inconvenience to your team who login to the system, as they need to know both the ip-address and the port number.

5. Change Login Grace Time (LoginGraceTime)

When you ssh to a server, you have 2 minutes to login. If you don’t successfully login within 2 minutes, ssh will disconnect. 2 minutes time to login successfully is too much. You should consider changing it to 30 seconds, or may be 1 minute.

Add the following entry to the sshd_config file to change the login grace time from 2 minutes to 1 minute.

$ vi /etc/ssh/sshd_config

LoginGraceTime 1m

6. Restrict the Interface (IP Address) to Login (ListenAddress)

If you have multiple interfaces on the server that are configured to different ip-address, you might not want everybody to login to the server using all those ip-address.Let us assume that you have the following 4 interfaces on the server:

  • eth0 – 192.168.10.200
  • eth1 – 192.168.10.201
  • eth2 – 192.168.10.202
  • eth3 – 192.168.10.203

By default ssh will listen on all of the above ip-addresses. If you want users to login only using ip-address 200 and 202, do the following in your sshd_config

$ vi /etc/ssh/sshd_config

ListenAddress 192.168.10.200

ListenAddress 192.168.10.202

7. Disconnect SSH when no activity (ClientAliveInterval)

Once you’ve successfully logged in to the system, you might want to get disconnected when there are no activities after x number of minutes. This is basically idle timeout.

In Bash, you can achieve this using TMOUT variable.

In OpenSSH, this can be achieved by combining ClientAliveCountMax and ClientAliveInterval options in sshd_config file.

  • ClientAliveCountMax – This indicates the total number of checkalive message sent by the ssh server without getting any response from the ssh client. Default is 3.
  • ClientAliveInterval – This indicates the timeout in seconds. After x number of seconds, ssh server will send a message to the client asking for response. Default is 0 (server will not send message to client to check.).

If you want ssh client to exit (timeout) automatically after 10 minutes (600 seconds), modify the sshd_config file and set the following two parameters as shown below.

$ vi /etc/ssh/sshd_config

ClientAliveInterval 600

ClientAliveCountMax 0

ESXi hosts failing to authenticate against Active Directory

You may noticed ESXi host may fail to authenticate to AD when lsassd service fails

To resolve the issues

  1. Place the host in Maintenance mode
  2. Connect to host using SSH
  3. Stop the lsassd services by runing  /etc/init.d/lsassd stop
  4. Copy the file /etc/krb5.conf from one host where the authentication works fine
  5. Start the lsassd services /etc/init.d/lsassd start

1. As you can see it fails to clone the following files:

e:\found.000\dir0004.chkold\

>4

>6

>8

“[2010-04-17 19:37:31.796 ‘App’ 1964 info] [stub,42] [Pcopy] Source file ‘e:\\found.000\dir0004.chkold\>4’ could not be copied (123)” 

The clone will not suceed until this is resolved.

 2. When trying to delete the files booted into the Windows OS presents the following error:

“The filename, directory name, or volume label syntax is incorrect.”

Windows cannot delete the files due to the special characters in the filename “>” which Windows does not allow.

Ironically it was windows check disk (chkdsk) that created these files.

You have to use Linux live CD to fix the problem. Windows got itself into that was stopping my P2V from working.

3. Download the KNOPPIX Live CD ISO and burn to CD.

4. Boot from the KNOPPIX Live CD

5. Once booted and logged in, open a terminal.

6. Now mount the NTFS drive in read/write (rw):

mount

(this will display current mounted drives – all are mounted read only)

 umount /mnt/sdc1

(this will unmount the required disk/partition – changed if yours is different)

vim /etc/fstab

add rw,

(edit fstab and on the line for your disk/partition change add rw)

mount /mnt/sdc1

(mount the disk/partition again – this time it is read/write)

rm -rf /mnt/sdc1/found.000/

7. Shutdown the server.

8. Boot from the VMware Converter CD and Continue your P2V.

Turn On Linux Servers Remotely Without Physical Access

Wakeonlan enables you to switch ON remote servers without physically accessing it. Wakeonlan sends magic packets to wake-on-LAN enabled Ethernet adapters and motherboards to switch on remote computers.

By mistake, when you shutdown a system instead of rebooting, you can use Wakeonlan to power on the server remotely. Also, If you have a server that don’t need to be up and running 24×7, you can turn off and turn on the server remotely anytime you want.

Overview of Wake-On-LAN

  • You can use Wakeonlan when a machine is connected to LAN, and you know the MAC address of that machine.
  • Your NIC should support wakeonlan feature, and it should be enabled before the
    shut down. In most cases, by default wakeonlan is enabled on the NIC.
  • You need to send the magic packet from another machine which is connected to the same network (LAN). You need root access to send magic packet. Wakeonlan package should be installed on the machine.
  • When the system crashes because of power failure, for the first time you cannot switch on your machine using this facility. But after the first boot you can use wakeonlan to turn it on, if the server gets shutdown for some reason.
  • WakeonLan is also referred as wol.

Check whether wol is supported on the NIC

Execute the following command in the server which you want to switch ON from a remote place.

# ethtool eth0

Settings for eth0:

Supported ports: [ TP MII ]

Supported link modes:   10baseT/Half 10baseT/Full

100baseT/Half 100baseT/Full

Supports auto-negotiation: Yes

Advertised link modes:  10baseT/Half 10baseT/Full

100baseT/Half 100baseT/Full

Advertised auto-negotiation: Yes

Speed: 100Mb/s

Duplex: Full

Port: MII

PHYAD: 1

Transceiver: internal

Auto-negotiation: on

Supports Wake-on: pumbg  [ Note: check whether flag g is present ]

Wake-on: g [Note: g mean enabled. d means disabled]

Current message level: 0x00000001 (1)

Link detected: yes

If Supports Wake-on is g, then the support for wol feature is enabled on the NIC card.

Enabling wol option on the Ethernet Card

By default the Wake-on will be set to g in most of the machines. If not, use ethtool to set the g flag to the wol option of the NIC card as shown below.

# ethtool -s eth0 wol g

Install wakeonlan package on a different machine

Install the wakeonlan package in the machine from where you need to send the magic packet to switch on your server.

Note down the MAC address of the remote server

Note down the MAC address of the server that you wish to switch on remotely.

# ifconfig

eth0     Link encap:Ethernet  HWaddr 00:16:k5:64:A9:68  [ Mac address ]

inet addr:192.168.6.56  Bcast:192.168.6.255  Mask:255.255.255.0

Finally, Switch ON the machine remotely without physical access

When the server is not up, execute the following command from another machine which is connected to the same LAN. Once the magic packet is sent, the remote system will start to boot.

# wakelan 00:16:k5:64:A9:68
