I see MPS Uniprocessor PC.  This image was installed with kvm.

It works under KVM-16 (which is the version that ships with Feisty) and 
up to kvm-24 (I did a manual binary search so a few versions were 
skipped).  versions 25, 26, 27 stall at boot (I wait several minutes but 
Windows never starts) and crashing with "unhandled vm exit: 0x9" happens 
with KVM-33.  I'm not on which precise version where the crashing begins 
(let me know if that would be useful).

A possibly unimportant note, I noticed that the later versions (above 
27) compile the executable as "qemu-system-x86_64" where as earlier 
versions build it as "qemu".  My system is a Centrino Duo, so it's a 
i386.  I'm not sure if this matters but I just thought I would mention it.

Let me know if you have any more questions,

Cam
