Hi,
I've installed the latest version kvm-33 on my PC. All guests (tested
with several knoppix version and SuSE 10.1 install dvd image) hanging on
reboot. In the host syslog I found a lot of messages (>1000): "kernel:
kvm: unhandled wrmsr: 0xc0000083"
I've tested with the original kernel kvm modules and with the modules
delivered with kvm-33, I tried the version kvm-32 - no success - every
time the same behaviour!
Can you try the attached patch?
