Hi All,

This might be a stupid question, but I have two PCI devices that I want to pass-thru to a PV domU. I can pass one of them, but not both. I'm sure it's a stupid syntax issue within my configuration file. When I do a "lspci" in the domU, (CentOS 5.1), only one of the devices shows up.

(e.g.) 00:00.0 Multimedia video controller: Internext Compression Inc iTVC16 (CX23416) MPEG-2 Encoder (rev 01)

The two devices are, (01:08.0) and (01:09.0) in dom0. If I do either of the following:

pci = [ "01:08.0" ] or pci = [ "01:09.1" ] in the configuration file, they'll show up.

I've tried:

pci = [ "01:08.0, 01:09.0" ]
pci = [ "01:08.0,01:09.0" ]
pci = [ "01:08.0", "01:09.0" ]
pci = [ "01:08.0","01:09.0" ]

No go on getting both passed. I'm sure I'm just doing something stupid with the syntax.

Any help would be appreciated!  Thanks!

P.S. Both devices are TV Tuner cards. I've verified the drivers for them in dom0 are not loaded/unbound and both devices exist in /sys/bus/pci/drivers/pciback/.
