Subject: RE: [Xen-users] HVM and gplpv disk question

tap:aio works for all of my linux domU's just fine.  I'm looking for the answer 
of if I should use this for my Windows HVM's which are running gplpv.
So, if I am to get it to work, what should I be using for the disk line in the 
config file for the HVM?

Can you confirm that tap:aio works with a regular PV domain but not with
HVM+GPLPV drivers? What about linux HVM and PV drivers?

I could never get tap:aio working with GPLPV but then when I upgraded to
3.3.1 it all 'just worked'.
