[one-users] libvirt unstalbe with open nebula

Thu Mar 24 23:07:12 PDT 2011

Hi,

I have install opennebula vers. 2.0.1-1 with libvirt vers. 0.7.7

When I create a virtual machine, it's working fine but few minutes after,
libvirt crash.

If I don't run any virtual machine, libvrit has no problem.

If I start a machine manually using virsh:
   - if opennebula is working: libvirt has the same  problem.
   - if opennebula is stop: libvirt has no problem

If seems that every 10 minutes, when opennebula try to monitor the virtual
machine, libvirt crash at the same moment.

In oned.log I have:

Fri Mar 25 14:59:02 2011 [ReM][D]: HostPoolInfo method invoked
Fri Mar 25 14:59:02 2011 [ReM][D]: VirtualMachinePoolInfo method invoked

Fri Mar 25 14:59:32 2011 [ReM][D]: VirtualMachinePoolInfo method invoked

And if I run libvirt in gdb + debug:

( I can provide more logs if necessary )

Does anyone met this situation or have any clues concerning the origin of
this problem?

Cheers,
