dafna, can you please clarify the scenario? what is "once snapshot is created"
when we move a disk we create a live snapshot. once snapshot is created -> after the live snapshot is created for the live migration.
the error will not occur in that scenario after bug 872277 resolution. still worth catching this Monitor timeout exception and set the correct message in VDSM error object
mistakenly closed it. proposed patch for VDSM and engine: http://gerrit.ovirt.org/#/q/topic:878064,n,z

there is CanDoAction added to the live storage migration + live migration. I tested after the CanDoAction and after the live storage migration ended + live migration of the vm. we cannot connect to the graphic server after the vm migrated but no exception moving to verified.
