Please remember to CC the xen-users list!

According to the NIC's page:
http://www.realtek.com/products/productsView.aspx?Langid=1&PNid=13&PFid=5&Level=5&Conn=4&ProdID=12

Your controller does not have SR-IOV! AFAIK, only some Intel
controllers have SR-IOV:
(Pause at 9:09, SR-IOV is on the right side of that list, not the left side)

You can check which controller has SR-IOV by checking its page at
http://ark.intel.com

Hope this helps
