[one-users] How to manage vm created by opennebula by virsh tools?

[Sharuzzaman Ahmat Raslan]

Hi Dennis,

When Opennebula shutdown a VM, it will destroy the XML file on the host,
and unregister the VM from KVM.

If you just want it to stop, so that you can do something to the image, eg.
making a backup, you can use the command

onevm suspend <vmid>

then the VM will still be available in the host, and can be queried by
virsh list command.
