I'll set any networking method if required. Main problem is to don't send dhcp requests from domUs to external network and don't accept dhcp requests from external network. In case of banal dhcpd xenbr0 it fails both purposes and i have to make firewall to drop those packets.
I thought about next config:
create virtual network with domUs on dummy0 interface, put dhcp there,
enable ip_forward, set dom0 as router for domUs using dhcp configuration.
this approach has only one flow: all my domUs got different cidrs, so i'll have to manually add them to dom0s routing table.
if i could make dhcpd to add routes according to static leases (looks stupid, i know, but i need 0-configuration networking) this approach would be the best.
