guest traceback after crash

Description of problem:
I had a RHEL-6 guest running for months on rhev-2.2.z (host kernel 2.6.18-272.el5). Recently, the guest was transferred to rhev-3.0-beta2, and started to halt after several hour of use.

Version-Release number of selected component (if applicable):
host kernel-2.6.32-131.12.1.el6.x86_64
guest kernel-2.6.32-71.18.2.el6.x86_64

How reproducible:
after several hours of usage

Steps to Reproduce:
1. start my guest
2. run gerrit inside it for several hours
3. crash

Sasha suspected that this is related to my guest having virtio NIC, changed it to rtl8139, but the problem persists.

qemu commandline for my guest is

Comment 2 Dor Laor 2011-09-21 08:43:52 UTC
There is not enough info in the stack trace. Was anything saving the the guest?
Can you import the guest outside so Gleb will play w/ it? or configure serial to collect the guest log? Was there any significant host logging?
