Maybe i have to define the VM first? Is > "virsh save dom" shutting down the VM? 'virsh start' would resume a managed-save guest, but we aren't using managed save. You want 'restore'. And yes, 'virsh save' shuts down the guest (we might enhance it in the future to leave the guest running after the save image has completed, now that we have a use case for doing so, but that won't help you with current versions of libvirt). -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
