Yes, you can use "lxc-autostart -g "groups" to start and stop groups of
containers but you also either have to use the -A option (not generally
recommended) or add the following option to the individual config files
as well:

lxc.start.auto = 1

Optionally, you can set the boot order in the group using
lxc.start.order and a delay after each container begins to initialize
with lxc.start.delay.  Starting 10 or 20 container all at once can be
rather (cough) harsh on the load average.  :-P

You can not destroy them as a group, though.

I'm working on code to assist with and control the autoboot process
using this mechanism when the host boots.  Currently, it will only
autoboot containers that are not contained within any group at the time
the host boots.
