Again, this is Gentoo specific. The network-bridge script tries to
figure out what netdev is by "ip route list default scope global"
and take the last word. On gentoo, the output of the command ends
with "... eth0 metric 2000". Therefore I use explicitly
(network-script 'network-bridge netdev=eth0').
If I don't make the links to net.vifN.0, I see in /var/log/messages
(on dom0) net.agent[pid]: add event not handled
and the vifN.0 is not brought up (but IS added to the bridge) and
it won't try dhcp.

On dom0, /etc/conf.d/dhcpd contains DHCPD_IFACE="eth0"
and the relevant part in /etc/dhcp/dhcpd.conf:

host CARDHU {
        hardware ethernet 00:16:3e:00:00:03;
        fixed-address 10.0.0.3;
}

There is no specific configuration for net.vifN.0 (not on dom0 and not
on domU) and therefore it defaults to dhcp.
It also makes no difference if I include dhcp="dhcp" in the domU
configuration file om dom0, or not.

Hans.
