You can certainly get network functionality in DomU - you just can't get
directly to the actual physical PCI device.
Generally, the DomU is linked to the rest of the world through a
"bridge" device - which is just a piece of software that transfers the
data to Dom0, where Dom0 decides whether it's going to send it to the
Ethernet card or just transfer it to another domain - or perhaps answer
itself (in case you ping dom0 for instance).
But if you really want to have direct access to the real hardware from a
DomU, then you need to use either Xen 2.0.x, or wait for the PCI
assignment feature in 3.0 to appear - I did see some patches a few days
ago, but I'm not sure if they are applied to unstable or not. There were
several comments and a bit of toing and froing on the patch, IIRC.
