[Pkg-xen-devel] Xen support patch for package `bridge-utils' available

[Thomas Schwinge]

Hello!

One month ago I created a patch and submitted it to the Debian
`bridge-utils' package's tracker: <http://bugs.debian.org/405215>.


I thought it may be helpful for others to know about it and wanted to
inform you this way, as the `bridge-utils' maintainers didn't make any
attempts so far to comment on it or even include it.


I use it this way:

dom0's `/etc/network/interfaces':

#v+
auto lo
iface lo inet loopback

auto br0
iface br0 inet dhcp
        bridge_ports regex (eth|vif).*
#v-

I.e. I have a bridge `br0' where all available `eth*' and Xen-created
`vif*' interfaces are added to and that is configured by dhcp.

In `/etc/xen/xend-config.sxp' I use ``(network-script network-dummy)''
and ``(vif-script vif-bridge)''; the former because the bridge is already
set-up and need not be maintained by Xen.

Instantiating domUs (with ``vif = [ 'bridge=br0' ]'') will then get their
virtual interfaces added to the `br0' bridge and -- and that's where my
patch to `bridge-utils' comes into play -- this will even surevive a
``/etc/init.d/networking restart'' (or similar actions) on the dom0: all
`vif*' interfaces will be re-attached to the bridge `br0'.


Regards,
 Thomas
