Hi,
on one of our servers, windows 2008 KVM suddenly crashed. I see following
in libvirt log:

I guess this is not of much use, since I didn't have debuginfo package installed
in time of crash. Is it possible to obtain more debuginfo after I installed it?
Is there something else I should check to find where the problem could be?
The system is quad core x86_64 with 32GB RAM, centos 6, running 3.0.51 kernel,
qemu-kvm 1.2.0
I'd be very grateful if somebody could have a look at this.
With best regards
