[libvirt] Workaround to start xen inside a buggy kvm

[Thomas Fricke]

Buggy kvm crashes with kernel panic if xen started inside a kvm machine.
kvm needs the -no-kvm-pit, this argument is not available with libvirt.

I have tested the following workaround on ubuntu 9.04

Rename kvm

cd /usr/bin
mv kvm kvm.orig

Use the following script instead the original  kvm

#!/bin/sh
exec kvm.orig -no-kvm-pit $*

Do not forget chmod +x kvm

Have fun,
Thomas
