is the vm preallocated or thin provision disk type? also, can you please attach engine, vdsm, libvirt and the vm's qemu logs? On 03/22/2013 11:59 AM, Nicolas Ecarnot wrote:
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

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.
