Bug Description

Recently my system has been updated the kernel to 2.6.28-13-generic. After this upgrade my guest OS in kvm does not start. If I load the previous kernel 2.6.28-11-generic, then everything works fine. Usually, I start kvm with the parameters

kvm -no-acpi -m 256 /home/and/Windows/image -redir tcp:5555::80 -soundhw es1370

But even in this form

kvm -no-acpi -m 256 /home/and/Windows/image

the guest OS can not start.

My guest OS is Windows XP. It freezes right before it is supposed to show its logo (black screen with the sign "Windows XP" and a progress bar under the sign).

Here is some information from dmesg:
when I start kvm in 2.6.28-13-generic I get

kvm: 3293: cpu0 unhandled wrmsr: 0xc0010117 data 0

If I start kvm in 2.6.28-11-generic, dmesg prints

[ 78.304120] kvm: 3279: cpu0 unhandled wrmsr: 0xc0010117 data 0
[ 103.835431] kvm: emulating exchange as write

I can confirm same problem. After updating latest upgrades (13.7.) to Jaunty Windows stops running. It runs if booted in safe mode.

Related to bug 379991. I am able to run Windows if add '-cpu core2duo,-nx' to kvm options as pointed in bug 379991.

Thanks, HarriR
Indeed, it seems that my bug is just a duplicate of bug 379991. I used the option
-cpu qemu32
now it works OK.
