[Users] Starting VM gets paused

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
