[Bug 850309] Re: libvirt fails to autostart VM attached to a bridged port

[Serge Hallyn]

For natty, the linked ifupdown tree (a compiled package of which is at
http://people.canonical.com/~serge/ifupdown_0.6.10ubuntu4.1_amd64.deb)
works for me.  Installing that, and then changing the 'start on' line in
/etc/init/libvirt-bin.conf to

start on (runlevel [2345] and static-network-up)

makes libvirt wait for all network devices to really be up and have ip
addresses.  As discussed on irc, if dhclient times out, then libvirt
will start anyway, but this is still a big improvement.

I'm assigning this to smoser for a quick sanity check.  smoser, if you
think it better than SpamapS take a look, please assign him, or assign
to me to bounce back to me.

Bug description:
  I have assigned my eth0 as the sole bridge port on bridge device br0.
  I have my VMs set to connect to br0.  When I manually start them,
  everything works well.  I have set one VM to autostart on bootup, but
  it fails.

  I found bug #495394, particularly comment 49 to be what I see
  happening.  In that bug, the person who wrote comment 49 was told to
  file a new bug report, but it seems he did not do that.  I am now
  filing the report.

  Attached is a syslog snippet that shows autostart failing.
