11.10 detects no NICs running in Xen domU

[Alan McKay]

He folks,

I've been working on this problem for quite some time now

dom0 is running on RHEL5.7 and I want to install Ubuntu 11.10 in a domU

So I've done a considerable amount of googling and reading the last 2
days, and finally figured out how to configure dom0 xen for 2 NICs.
For the longest time I was not seeing what I was expecting to see
doing 'ifconfig' on dom0.  Now I see :

eth0, eth1, lo, peth0, peth1, vif0.0, vif0.1, vifX.0, vifX.1, xenbr0, xenbr1

And I have confirmed with a CentOS 5.8 domU that the NICs are working.

But damned if I can get them working under Ubuntu 11.10.   And more
googling is not getting me an answer.

Does someone have a quick link at-hand to help me out here?

This does not help - it assumes the NICs are there :
https://help.ubuntu.com/community/Xen#Network_for_DomU

I do "lshw | grep -i eth" and get nothing.
