Description of problem: With the latest stable kernel (2.6.16.6-79.fc9.x86_64) in a kvm virtual machine, starting X makes the machine go to 100% load, and the only way to recover is to destroy the vm and restart it. Older kernels have no problems. Not using X is also ok. Latest kernel + X == FAIL Happens only when the guest uses x86_64 afaics, a previous test with an updated vm with i686 didn't show any problem (but I deleted that vm so I cannot retest now). The host is a T60 laptop with this same x86_64 kernel.
