I can = confirm this as I also loose any network connection to the VM and the ability to connect a console. Also, the only thing witch 'fixes' the issue is right now 'kill -9 <pid = of qemu-kvm process>' As far as I can tell the VM became unresponsive at around Sep 15 = 12:30:01; engine logged this at 12:34.
