Hi, After two months of stable usage of this 3.1 oVirt setup, here comes the first blocking issue for which I've no other mean to ask some hint. When I'm starting a VM, the start process is running fine. Being fast enough, we can ssh-connect to it, but 5 seconds later, the VM is paused. In the manager, I see that : 2013-03-22 09:42:57,435 ERROR [org.ovirt.engine.core.vdsbroker.vdsbroker.VdsBrokerObjectsBuilder] (QuartzScheduler_Worker-40) Error in parsing vm pause status. Setting value to NONE 2013-03-22 09:42:57,436 INFO [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (QuartzScheduler_Worker-40) VM serv-chk-adm3 3e17586d-bf8f-465b-8075-defaac90bc95 moved from PoweringUp --> Paused And on the host, I see one warning message, no error msg, and many looping repeated messages : * Warning : Thread-1968::WARNING::2013-03-22 09:19:18,536::libvirtvm::1547::vm.Vm::(_readPauseCode) vmId=`3e17586d-bf8f-465b-8075-defaac90bc95`::_readPauseCode unsupported by libvirt vm * Repeated msgs, amongst other repeated ones : Thread-1973::DEBUG::2013-03-22 09:19:20,247::libvirtvm::220::vm.Vm::(_getNetworkStats) vmId=`3e17586d-bf8f-465b-8075-defaac90bc95`::Network stats not available Thread-1973::DEBUG::2013-03-22 09:19:20,247::libvirtvm::240::vm.Vm::(_getDiskStats) vmId=`3e17586d-bf8f-465b-8075-defaac90bc95`::Disk hdc stats not available I made my homework and found some bugs that could be similar : https://bugzilla.redhat.com/show_bug.cgi?id=660598 https://bugzilla.redhat.com/show_bug.cgi?id=672208 and moreover : https://bugzilla.redhat.com/show_bug.cgi?id=695393 - I tried to restart the node's vds daemon : same behavior - I tried to reboot the node : same behavior - I tried to to restart the manager's engine : same behavior - I tried to run this VM on another node : same behavior - I tried to run another VM on the node I saw the issue : the other VM is running fine. I don't know if I have to conclude that this issue is specific to this VM, but I sounds like yes. Things to say about this VM : - it it a RH6 IIRC. It has already been successfully started, migrated, stopped and rebooted many times in the past. - it has 3 disks : one for the system and two for datas. - it has no snapshots - it has no different or complicated network setup My storage domain is a SAN, iSCSI linked, and doing good job since months. I must admit I'm a bit stuck. Last thing I haven't tried is to reboot the manager, though I'm not sure that would help. -- Nicolas Ecarnot
