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.
