I have a similar experience using Xen 4.0.1, with linux pvops kernel
(2.6.32).
Somehow, i never seemed to get the 'Bios boot' to work, however, when
passing these cards through to the DomU, then the following
combinations
seem to work fine once started:
- Ubuntu Lucid (64bit) + Catalyst (10.7 or 10.8) (primary or
secondary)
- Windows XP (32bit) + Catalyst (10.7 or 10.8) (primary, have not
tried as secondary)
- Windows 7 (64bit) + Catalyst 10.9 (primary, have not
tried as secondary)
Note that when trying the opensource driver on ubuntu, it exits with
errors, which seem
to indicate it can't find the Bios.
I have a Asus P7P55D-Evo mainboard, with two Asus EAH4350 graphic
cards,
both cards are passed through to a domU, both don't show bios messages
on
boot (even when i use graphics passthru setting), but they work fine
with the installed drivers after the domains have booted.
For me, that's good enough ;-)
Regards,
Mark.
