NetBSD now has Xen 4.1 too. Recently committed patches have enabled HVM
guests to properly detect phy: storage. See recent port-xen (netbsd) for
more information.

If you're on NetBSD -current and not using LVM, keep in mind that's an
option too -- even though presently, renaming/destroying lvs doesn't
work (bin/44947).

If using XENHVM, you should see a xn0 interface on ifconfig output. Just
setup networking there instead.

By coincidence you're also using NetBSD as the dom0, please let us know
if you hit the same problem I did (see my recent post on this list).
