Yes, that's what I'd expect (although you can choose one of three
different network card types [at least in the latest version(s)]. 

It is currently not possible to connect a real network card to a HVM
domain, as that requires address translation from the guest to the
machine memory addresses. If you look for a recent post by me in the
Xen-devel mailing list, you'll see what I mean. 

Note that the 10Mbps is irrelevant, as this is a FAKE network card
supplied by the device model that the virtual machine uses to "simulate"
the hardware inside the virtual machine.

That's news to me, as I think Xen enterprise actually uses the same
Xen-kernel as the open source version, but has other add-ons.

I wouldn't know that - there is a mailing list for Xen enterprise.
