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

[Serge Hallyn]

What we need is to have the static-network-up (plus subsequent fixes)
SRUd to lucid..natty, and to have libvirt-bin wait on static-network-up
rather than on 'stopped networking'.

@Robert,

as a workaround, I would suggest you change your /etc/init/libvirt-
bin.conf to add a 'sleep 5'.

So in place of

# If you used to set $libvirtd_opts in /etc/default/libvirt-bin,
# change the 'exec' line here instead.
exec /usr/sbin/libvirtd $libvirtd_opts

You would now have

# If you used to set $libvirtd_opts in /etc/default/libvirt-bin,
# change the 'exec' line here instead.
script
    sleep 5
    exec /usr/sbin/libvirtd $libvirtd_opts
end script

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.
