Hi
This is my system: Fedora 19 libvirtd (libvirt) 1.0.5.7 ( I downgraded to this kernel version trying to solve the problem, but no luck.)
------------- This is the error message:

I was running a virtual machine using qemu-kvm.
What i already tried: - memtest -> no error. - formatted and installed only the base system (no DE). - downgraded kernel: 3.9.5-301.fc19.x86 - swapped the disk with another server (no error with kernel 3.9.5 but i could only test during some hours, i dont have an extra machine anymore)
Any suggestions? Thanks, and sorry my not-good english
