Description of problem:
Restoring a snapshot works but I cannot access via spice fails with "Error while executing action SetVmTicket: Unexpected exception". Also the engine shows an error starting the vm even though it starts successfully.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create a VM with an OS, start it, make a snapshot and stop it.
2. start the vm and start a process (in my example: cat /dev/zero)
2. Create a RAM snapshot
3. Shutdown the vm
5. Restore the RAM snapshot
6. Start the vm and open spice console

Actual results:

Raz, how is this storage related? I'd say it's more virt

Raz, are you sure the VM is properly up and running?

2015-11-03 22:24:13,346 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-19) Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: VM vm_ram_snapshot_nfs is down with error. Exit message: Wake up from hibernation failed.

Which VM is the problematic one in the logs?
Comment 3 Raz Tamir 2015-11-05 08:51:44 EST

Yes, I successfully ssh to the vm to make sure the cat proc (step 2) is still running.
The problematic vm is vm ram_snapshot_nfs
