Hi Ryan,

thanks for this set of instructions.
I was able to obtain the xswindrivers.iso file that way and install
it into my virtual Windows XP machine. Unfortunately, when trying to
reboot Windows immediately complained that it could not read from
the hard disk, even though I did change the 'vif' and 'disk' config
lines to

vif = [ 'mac=00:16:3e:00:00:66, bridge=xenbr0' ]
disk = [ 'file:/Data/xen/bat-xp.img,hda,w' ]

Actually I wouldn't even need to change the disk access method,
because access to the disk works well as it is (with hardware
virtualization). All I need is better network performance.

Is there a way to install only the PV network driver, leaving the
disk driver alone?
Or am I doing something else wrong here?
