There are any lists like Hardware Compatible List to Xen
Most NICs that are compatible with CentOS will also be compatible with Xen. I doubt your problem really is the card by itself. I'd rather think it's a driver or the way it's plugged into your PC. If I understand you correctly you already tried two cards and both failed in some way. I think that might point to the latter cause I mention. It might also help if you would tell about your hardware. Nowadays the NIC is usually embedded on the mainboard, so you must be either using old hardware or using the external NIC for a good reason.
