autostart on boot not working

[Florian Engelmann]

Description: Ubuntu 14.04.4 LTS
Release: 14.04

lxc:
  Installed: 1.0.8-0ubuntu0.3
  Candidate: 1.0.8-0ubuntu0.3

Upstart service /etc/init/lxc.conf should start all LXC containers having set "lxc.start.auto = 1" if /etc/default/lxc got LXC_AUTO="true".

This does not work on a "reboot"/"shutdown -r now" but it does work after a reboot using "restart lxc".

It fails because of missing network devices (early boot up stage):

lxc-start: conf.c: instantiate_veth: 3105 failed to attach 'vethMCUSEO' to the bridge 'lxcfr258': No such device
lxc-start: conf.c: lxc_create_network: 3388 failed to create netdev
lxc-start: start.c: lxc_spawn: 856 failed to create the network
lxc-start: start.c: __lxc_start: 1121 failed to spawn 'xxxxxxxxxx'
lxc-start: lxc_start.c: main: 341 The container failed to start.
lxc-start: lxc_start.c: main: 345 Additional information can be obtained by setting the --logfile and --logpriority options.

We do use a special veth setup but the lxc upstart service should still cover this case.

any news?

This is fixed in modern versions of LXC using systemd.
