Hi, today I've noticed that one of my VMs was paused. I took a look at the engine.log and found only this: 2014-09-09 04:00:09,017 INFO [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (DefaultQuartzScheduler_Worker-46) VM XXX 8ad326be-5103-498a-a11d-0ea1eee4bbf4 moved from Up --> Paused The vdsm log provides a better error message: libvirtEventLoop::INFO::2014-09-09 04:00:07,279::vm::4574::vm.Vm::(_onIOError) vmId=`8ad326be-5103-498a-a11d-0ea1eee4bbf4`::abnormal vm stop device ide0-0-1 error libvirtEventLoop::DEBUG::2014-09-09 04:00:07,279::vm::5176::vm.Vm::(_onLibvirtLifecycleEvent) vmId=`8ad326be-5103-498a-a11d-0ea1eee4bbf4`::event Suspended detail 2 opaque None Still, I don't know what exactly caused this. Only *one* VM was affected, so I doubt it was a general error on this host. Does anyone have an explanation for this? ovirt-engine-3.4.3-1.fc19.noarch vdsm-4.14.11.2-0.fc19.x86_64 Regards - Frank
