Hello=2C
I upgraded oVirt yesterday from 3.4.2 to 3.4.3 and performed a yum upgrade =
on all ovirt nodes as well without rebooting any of them.
After completing the upgrade=2C I tried to perform manual migration of VMs =
to a different host. The result was that all Windows 2003/2008 and CentOS =
5 VMs were migrated successfully without any issues but all CentOS 6.5 VMs =
crashed although migration was completed successfully.
By looking the console of the CentOS 6.5 VMs I noticed that a few seconds a=
fter migration was complete=2C all the processes were killed=2C many out of=
memory errors were thrown as well as messages like "virtio_balloon virtio3=
: Out of puff! Cant' get 256 pages" and the VM ended up in kernel panic so =
I had to perform a manual poweroff and start the VM again.
Any ideas of what might be the cause? I have opened an urgent Bug for this =
(https://bugzilla.redhat.com/show_bug.cgi?id=3D1123274)
Thank you=2C
Sokratis
