I've got a (longish) bugreport about qemu-kvm not working on an AMD bulldozer CPU. In particular, winXP guests which worked fine before, after upgrade of the host CPU stopped working with a BSOD, and no new winXP install can be completed due to installer freezing somewhere in process.
I don't have any bulldozer CPUs anymore to verify (I had access to two machines briefly and haven't noticed any issues when ran my old "rescue" XP guest). We tried different -cpu options, and neither appears to work fine. We also tried qemu-kvm 1.0 and 1.1, 1.1 works a bit better but some questions remains. The whole report is at http://bugs.debian.org/676950 . So, the question is: has anyone tried running this stuff on a bulldozer cpu? And, any hints about debugging this? Thanks, /mjt
