RE: [Xen-devel] multicast?

["Andrew Warfield" <andrew.warfield@xxxxxxxxxxxx>]

Multicast certainly does not have explicit support within Xen at the moment
-- the current zero-copy code kind of implies single-sender,
single-receiver.  If you are just trying to get a single guest to
participate in a (physically) external multicast group though it should work
fine.  You'll just need to add vfr rules to map the multicast address in to
(and out of) that domain.

Copying packets and allowing multiple-guest delivery is on the list of
things to address in the next iteration of the network code, as it's
something we would like to have for i.e. traffic logging.  This is pretty
unlikely to happen until the I/O subsystem reorganization is complete
though.
