[Users] attempted live snapshot, machine paused, wouldn't restart

[Haim Ateya]

Hi Erik, 

in order to debug it, we need some more details, such as engine and vdsm logs, can you please attach those logs from the moment you took the snapshot?
from the log below, it seems as if vm resume operation succeeded and vm state changed to powering up.
btw, did you have an operating system installed on this vm ? what was the status of the vm prior to the live snapshot attempt?

Thanks.
Haim
