XCP-NG few basic command lines- CLI

Run the following command to list VMs and their UUIDs:

xe vm-list resident-on=<uuid_of_host>

Try the shutdown command with force:

xe vm-shutdown uuid=<uuid_of_vm> force=true

Restart the toolstack on the host by using the following command:

xe-toolstack-restart

Restart the host.

shutdown -r now

If the VM is still not shutdown, you might need to destroy the domain. However, the steps given below can cause problems for your VM and should only be done as a last resort.

Run the following command using the domain ID from the output of the previous step:

xl destroy <domain_id>

After destroying the domain, reset the power state.  The force is required on this command.

xe vm-reset-powerstate uuid=<uuid_of_vm> force=true
