Hello,
I am having an intermittent issue where one of my KVM guests is locking up and when checking the process its running @ 100% cpu. The host is CentOS 6.4 running the kernel kernel-2.6.32-358.0.1.el6.x86_64.
Would it be worth attempting to compile a 3.2 kernel and use the latest qemu-kvm package instead ?
Thanks.

This problem still persists :( I have read a few articles about setting the clocksource to acpi_pm and the guest was stable for a couple of days, then low and behold the CPU on the guest started to climb too 100% and completely froze. Only way to recover it was hard reset on the guest machine :( Any thoughts ?

Froze again :( would it be worth upgrading to a new kernel on the host instead of using the stock once from CentOS 6.4 ? I am not overcommitting memory of the machine so believe that is ruled out. I installed watchdog on the guest as-well to reboot it this happened again but that did not work :( Any thoughts on how to resolve the problem ? Here is how the guest is being started:
