Realtek ALC662 not found on Xen DomU HVM

[kubla]

Hi folks,

I have just loaded Windows 7 on a Xen HVM DomU (Solaris Dom0)
There appear to be a couple of issues I need to figure out, one of
which is that the Realtek ALC662 / VIA® VT1708S / VT1705 on
the ASRock N68-S motherboard isn't being detected.

I can see it from the Dom0 Solaris:

pci bus 0x0000 cardnum 0x05 function 0x00: vendor 0x10de device 0x03f0
nVidia Corporation MCP61 High Definition Audio
CardVendor 0x1849 card 0x3662 (ASRock Incorporation, Card unknown)
STATUS 0x00b0 COMMAND 0x0006
CLASS 0x04 0x03 0x00 REVISION 0xa2
BIST 0x00 HEADER 0x80 LATENCY 0x00 CACHE 0x00
BASE0 0xfbff8000 SIZE 16384 MEM
BASEROM 0x00000000 addr 0x00000000
MAX_LAT 0x05 MIN_GNT 0x02 INT_PIN 0x02 INT_LINE 0x0b

The Device Manager does show problems with a PCI device on
bus 0 device 3 function 0 which is odd since there isn't anything
reported by Solaris bus 0 device 3.

Could this be my missing audio?

Anyone encountered anything similar?

Anyone know of a PCI scanner that will run under Windows 7?

Kind regards,

Kubla

Turns out it's actually "Xen Platform Device (rev 01)"

Sadly it appears the problem is that the Solaris Dom0 doesn't
support PCI pass through yet & isn't likely to for some time :-(

It's live with no audio in DomU or install a variant of Linux
for the Dom0 rather than Opensolaris. <sigh>
