vMotion failing at 10% with error ” Necessary module isn’t loaded”

If you encounter this problem of  vMotion failing at 10% with error “Is not Necessary module loaded.”

then here are the steps to restore vMotion functionality:

To workaround this issue:

  • From ESXi command line, run this command to load the module: esxcli system module load -m migrate 

Note: It may be necessary to run this command on the source and destinations ESXi hosts.

  • Connect to vCenter Server through the vSphere Client.
  • Select the ESXi host and click the Configuration tab.
  • Click Software > Advanced Settings.You see that Migrate.Enabled is set to zero because the module was not loaded earlier.
  • Set Migrate.Enabled to 1 and click OK.

After this your problem will be resolved.
