Actually, SLES was being used as both dom0 and domU. At first, I was
running with full-virt and then by the time the reply to my request had
come, I had already switched to para-virt. My results via pra-virt are
exactly as you have described. I am able to pick up 1Gbs nics
automatically. This is puts me closer to where I want to be and livable for
the time being. I am still looking for any ideas on achieving the link as a
10Gbs connection, though.
