if the volume was in use by the vm you'll have to reboot it to  
properly release all open files. As far as I know a snapshot of an  
instance booted from volume will only snapshot the respective volume.  
That should still be possible, but I guess it would be inconsistent  
because of the open files. Is reboot not an option?
