[ovirt-users] Single VM Down After Attempted Snapshot

[Clint Boggio]

Greetings users;

I've got a single VM in a 3.6 environment that is in a down state after
and attempt at creating a snapshot via script, and  exporting said
snapshot to the export domain. I see some indications of what could
possibly be wrong in the filtered engine.log, and i'm at a loss on how
to repair the problem. Below is a "tailf" of the engine.log as i attempt
to run the VM in it's current state. Any guidance or wisdom would be
much appreciated.
