Restart a hanged virtual machine | XenLens

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:

xe vm-list

Get the vm domain id by uuid:

list_domains

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

linux - Determine which guest is running on XEN: HVM or PV guest - Server Fault
A quick note, there are actually 3 modes, not two when it comes to the drivers in use:
```
HVM: unmodified kernel and drivers using software emulated devices
PV-HVM: unmodified kernel with paravirtualized (Xen specific) disk and network drivers
PV: modified kernel and drivers
```
For a Xen guest/DomU you can do a very basic uname and lsmod with a grep to list the modules in use:

uname -a
lsmod | grep xen

If uname -a lists a kernel with the string "xen" in it, then you have a modified kernel and it's likely a PV guest, and you will see output from the lsmod command to confirm it. If you have output from the grep on lsmod but no sign of a modified kernel then you are PV-HVM. Without any sign of either, it's a straight HVM.

Note: Generally you can do more with VMs that have the PV tools installed, so that can be quite an obvious pointer, however you can fake the presence of the PV tools to allow suspend/resume etc. so you cannot rely on that in general.
