Update:
I made several errors while setting the vm up.

1.
I had not checked that the dom0 was able to setup interfaces on the dual
port card. It wasn't. It turned out that udev assigned "eth1" to both
nics. Once that was rectified the first interface showed up in the vm.

2.
In the domU configfile I specified the nic this way:
[ '0000:06:00.0' '0000:06:00.1' ] and not the correct way:
[ '0000:06:00.0', '0000:06:00.1' ].

Once I put the comma in the pci line, the second interface showed up in
the vm.


So: mission accomplished, time to go to bed.
