No, there are about 15 VMs on this Host. There are Vista, W2k3, w2k8 and debian linuxes running. I think all OSs are x64-systems. If I look at the time, when this error shows up in the kernel-log, it matches exactly the time, when the machine is rebooting. Currently I try to use the windbg-tool.. but no success so far.. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
