Hmmm... well according to the logs the fact that it is tap:aio doesn't
seem to be a problem - it's past where it crashes on my system when I
try with tap:aio.

I have uploaded a version of xenvbd.sys with a whole load of debug
statements in it which should give me more of an idea about what is
going on.

I have uploaded xenvbd-xp-debug.zip to
http://www.meadowcourt.org/downloads, please put the xenvbd.sys file in
c:\windows\system32\drivers and reboot and send me the debug output from
that.

Thanks

James
