hi.

for domain migration, this is an obvious procedure in order to announce
the relocation of the guest being bridged on a different host.

i've been grepping around the xen build tree to see whether and where
this is covered. haven't found anything yet. is this covered by linux
kernel bridging already, or is it just missing [read: left as a
scripting exercise to administrators]?

hints welcome.

thanks,
daniel
