  Hi,

BTW: is there a tool (or pciutils patch) which can decode the virtio
capabilities?

Searched for a patch today, and all google found me was this mail asking
for one :-o

So I went ahead and coded one up.  Attached.

While hacking it up I've noticed spec doesn't match reality.  The
"Virtio Structure PCI Capabilities" section here ...

http://docs.oasis-open.org/virtio/virtio/v1.0/cs01/virtio-v1.0-cs01.html#x1-690004

... doesn't match what qemu is doing.  Huh?

Thanks a lot for the report, and the tool!
I sent patches to fix this all up.
You can try my qemu and linux virtio-net branches now,
they should be spec compliant.
