I ran "tail -f /var/log/vdsm/vdsm.log |grep ERROR" while attempting a live migration and nothing is coming up, but
"tail -f /var/log/ovirt-engine/engine.log |grep ERROR" returns:

Subject: Re: [ovirt-users] Error creating Disks

Since LiveStorageMigration is a complicated and long task which divides 
into 4 different jobs I asked for the log with the echo before the task 
so we can easily follow the task from start to end.

however, I did grep for the task id in the logs you just attached and 
there is nothing there.
I'm adding Elad to try and see if he can reproduce ERROR populated by 
engine because of cache.
