Well I'm all for sanity checks, not having realized that anything beyond
"vt support" was needed. This is new territory for me, but based on my
host lspci output (below), I'm guessing that I've got a 3100 chipset,
which seems not to support vt-d, leaving me SOL.
Can you confirm I'm interpreting this properly, or offer some other
means to determine vt-d support? Many thanks!

I've got a Digium PCI telephone card that I'm trying to use with an
AsteriskNow guest, on a CentOS 5.2 host. I've tried setting up the pciback
stuff, and think I've done it right, but the card does not show up in the
guest. I'm obviously missing something, so any help (including ways to
debug this!) would be greatly appreciated.
Here's some more info:
The guest is fully virtualized, so I'm assuming that nothing should need to
be configured within the guest.
Just a sanity check, proper IOMMU support, such as Intel VT-d, is needed
for passing devices to fully virt guests. Does your system support VT-d?
Cheers,
Todd
