[Xen-devel] Questions/Help with network/IP setup
Hi again I''d ideally like to let my vm''s/non-0 domains use DHCP (so I can reuse root-fs images etc), but I would also ideally like to specify the IP address when launching (xm create''ing) the domain. Is there an easy way to do this? I see that I can specify the MAC address in the set-up script, so I could presumably fiddle the ''normal'' DHCP server to serve up the appropriate IP address according to the MAC address. However, I''d prefer the Xen/domain-0 to intercept the DHCP request or something, so that I can keep things local. I''m also a little confused as to the exact semantics of the network settings in the xm create config files. I see there are fields to enable/disable (some level of) dhcp, and supply a gateway, net mask and host name, but I haven''t been able to nail down exactly what these do and how they interact with the normal DHCP process within the vm.

You should be able to just create a wrapper script that updates your dhcpd3.conf and rehups dhcpd...
