I was trying to say, but not very well, that when qemu-kvm is running a
guest and X is running, whether it's on the local video hardware or not, I
get a kernel panic.

So now I've found I can run X without problems and I can run qemu-kvm
without problems, but I cannot run both at the same time.

I wonder if an older version of the kvm package would work around this, or
maybe an older version of the kernel.

kernel: 2..18-274.3.1.el5
kvm: 83-239.el5.centos

 A vncserver session not attached to the local console should also
