When I restart a busy server (running several containers, creating 100%
IO load for about 10 mins after start), my lxd containers do not
autostart reliably.
If I start them manually later on, they start fine (although "lxc start
containername" needs a while to return).
Is there a way to make lxd autostart more reliable? Perhaps it's some
kind of timeout which needs to be increased somewhere?
In the log, I can see:
lxc 1453630080.796 ERROR lxc_cgmanager -

not send a reply, the message bus security policy blocked the reply, the
reply timeout expired, or the network connection was broken.
