[Bug 1130007] [NEW] kvm guests stuck (not in io) and cannot be killed using -9

2013-02-19 Thread Corin Langosch
Public bug reported: I have two stuck kvm guests hanging in state R (for several hours now) on two different hosts. Actually they are not consuming any CPU and cannot be killed with kill -9. They are not responding to anything. Both systems are Ubuntu 12.10 Quantal running on a AMD II X4 965
