to add user experience: I tested on 3 VM's: 1 migrated with no errors, one was put in pause and I tried to start it became non-responsive and the third failed migration
Note that the source shows all kinds of errors, due to bug 701106. Federico, any idea why vdsm/utils:526 does not log any backtrace?
Dan, I suppose the problem is in the SimpleLogAdapter (logUtils.py:5). The backtrace is back if in vdsm/vm.py:492 you comment out: self.log = SimpleLogAdapter(self.log, {"vmId" : self.conf['vmId']})
Dafna, please reproduce this with the next vdsm build, where we added useful logging.
