I wouldn't say *way* down. I mostly use my hvm for multimedia that wine or
mplayer/xine can't handle, and that's a real cpu hog on an hvm guest,
especially video.

What log file in particular? (c:\windows\...) I've just recovered from a bad
chkdsk relocation of my home directory, plus some anti-virus & anti-trojan
checker files, but that happened after I installed 0.6.5. (Which reminds me,
you never answered whether it's better to do an upgrade with Device Manager,
or straight copies to c:\windows\system32\drivers?)

disk=[ 'file:/var/lib/xen/images/winxp,ioemu:hda,w',
'phy:/dev/cdrom,hdc:cdrom,r' ]
tap:aio: (actually tap: for hvm guests) stopped working after the upgrade from
fc7 to fc8.
