[kvm-devel] guest reboot hanging - kvm: unhandled wrmsr: 0xc0000083

[tadomeit <tad...@co...>]

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!

My startup command (without problems if using using the -no-kvm option):
qemu-system-x86_64 -boot d -m 384 -cdrom
/data/temp/SUSE-Linux-10.1-GM-DVD-i386.iso
