I''ve been setting up the same thing today. For some reason,
I''m having
issues getting it to work by specifying the pci = in the domU config. When I
create a domain using ''xm create -c mydomU pci=12,04,01'' it
works. Though,
that is the second port on my SCSI card and for sanity I''m pretty sure
I
need to be assigning both to my domU. I can''t seem to get it to take
both
12,04,00 and 12,04,01 at the same time.
Also, I''ve setup a mythTV backend as domU before. It worked fine for a
while, passing the PCI tuner card through. When I added a second (different)
card, I could not get that card to pass through, so I had to go back to
stock Linux kernel on that machine. Too bad, it was great to have a test Xen
machine at home.
Anyone else doing this lately? I was starting to wonder if my issues are
SLES10 related, as I''ve only done Xen on Debian until now.
