this is from a different day and/or a wrong log.
I need to know which error you are referring to

Comment 7 Michal Skrivanek 2013-03-06 13:41:48 UTC
moving to beta2 until it's clarified this is a real issue or not.
Need to get time of the failure and all of engine, vdsm, libvirt and qemu logs

Comment 11 Saveliev Peter 2013-04-02 15:59:30 UTC
Elad, can you point me to the exact timestamp of the case?

I see several qemu crashes in logs, but no one that can be interpreted as a bug description.

Comment 15 Elad 2013-04-03 13:50:02 UTC
Closing the bug for now because of reproduction difficulty issue. 
Will reopen as soon as we will manage to reproduce.
