Well after upgrading 0.9.6 (actually, first uninstalled those with the 
pre-0.9.0 instructies because of bsod when doing normal upgrade) I get 
instant lockups when doing anything I/O intensive! The domU will use 
100% CPU and just hangs forever as it seems (destroyed it after 5 min). 
The previous 0.9.6 seemed to be pretty stable, no lockups or whatsoever 
(and I'd already liked it's HD performance!) So not sure what's going 
wrong here, but in the meantime I get back to 0.9.6 (or I'll might also 
test 0.9.7 to clear things up).
