Screenshot of kernel dump
Comment 3 Martin Betak 2013-04-26 11:42:47 UTC 
Hi, I may have experienced similar issue during high memory load (compiling oVirt, running ecipse, chrome, .. etc) and running nested virtualization via qemu-kvm. It usually happens when the compiler enters the most memory intensive phase of compilation (also swapping heavily, I have only 8GB of RAM). 

In the attachment I include a screenshot of the kernel dump. Sorry for the bad quality.

Martin,

Can you reproduce with the instructions at https://bugzilla.redhat.com/show_bug.cgi?id=924916?

Marking this bug as a duplicate of that one.
