I think those first 4 ports should pass thru, but the last ones Im not sure about because those appear to be a sub device and I haven't had much luck passing just the sub piece. You should be able to pass 1:00.0 or 2:00.0 etc and it should show up as ethX in your DomU at which point it is 100% regular linux networking.

  So it should work when I set up my networking as described
 in the Manual, 5.3.1 ?

are you using PCI passthru? If you are passing each device directly to
the DomU, then it will just be standard linux networking.  Being onboard
though, I suspect you are dealing with some sort of realtek switch
fabric that shows up as a single PCI device (roboswitch type) and you
would not be able to pass that thru.  Can you do an lspci and show us
how those devices present themselves?

  I have a hardware here with 9 NICs (8 of them on-board)
 and I want to set up 8 NICs as real network interfaces,
 one for each xen domain. The 9th NIC should be Domain-0
 which is working well. Currently I have only set up
 one domain which is running in bridged mode at the moment.

  I am currently trying to set up a second domain which
 uses eth2 but I didn't succeed. I want to get the
 system run with 8 domains in which every guest is
 using one NIC.

  Is there some documentation or FAQ about how to set up
 this configuration?
