Dhcp makes migrating domU''s from real hardware to a Xen domU?
Interesting, I thought it''s just delivering IP configurations :)

The "ip", "gateway" and "netmask" settings only
affect the Xen
networking scripts, mainly in routed, but probably also in nated mode
(never used natted mode myself). They do not actually change the
configuration of your DomU''s interfaces.

That is the way to go - configure a static IP in the domU itself.

Apart from the things said, look at the "vif" config line - why did
you comment it out?
If you tell Xen that your VM shouldn''t have a network interface, it
will not have one.
Read the Xen manual about configuring network cards, and look at the
example configs to correct this (hint: try just commenting the vif
line back in).
