Restart a hanged virtual machine
Posted on June 29, 2012 at 16:19. Written by admin
Sometimes it may happen that your vm has hanged and XenCenter controls(Reboot and Force Reboot) do not work.
You may see an error when you try to force a reboot (The operation could not be performed because a domain still exists for the specified VM.).
This is a process to reboot the hanged vm from the XenServer host console.
To get the uuid of the VM that is hung:
Get the vm domain id by uuid:
Then destroy the domain of the vm:
/opt/xensource/debug/destroy_domain -domid <domid>
Now you can force a reboot on your vm:
xe vm-reboot uuid=<uuid> --force
If it has no effect you can also try:
xe vm-reset-powerstate uuid=<uuid> --force
Note that it may take up to 3 minutes to complete.
