[Users] Starting VM gets paused

[Nicolas Ecarnot]

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 :

by libvirt vm

* Repeated msgs, amongst other repeated ones :

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.
