We have several win2008 std (not r2) installations. Many of them 
suffered of system hangs (blue screen) or cpu 100% hangs while other 
guests were still running fine. Updating the bios solved all those issues.

We found out though that the most stable setup is using IDE and e1000 
(no virtio devices). Have you tried this?

Also, have you tried to put "args: -no-hpet" in the vm config file?
