So what I'm asking is "Is it possible to create a xen VM that has two virtual ethernet interfaces on a host that has only one real NIC"?

IMHO you can create an empty* bridge interface on a virtualization host.

*By 'empty' I mean no IP address and no real interfaces bridged.

By the way, there's KVM already on CentOS 5.8, so if you're going to move to CentOS 6 you'd better try KVM now. The solution I proposed earlier works for me with KVM. KVM in C5.7 was not production-ready, but it did work.

KVM absolutely requires CPU hardware virtualization extensions and requires 64bit CPU for any real production use due to RAM requirements.
