That's already covered by my proposal and I believe covered in the use cases listed within it. "lxc-stop -g any" That'll stop all containers that are in the "any" group. "any" is documented as being a special group that contains all containers even if they have lxc.group set. As you're not passing the "-a" flag, then the stop command will affect all containers even if lxc.start.auto is 0. > For my own part, if I want to stop the LXC server, then I > don't care whether the containers were started manually or > automatically.

Indeed and that's specifically why I added the "any" group to my proposal. > And one question: > > Do lxc-start -a ... and lxc-stop -a ... start/stop all LXC > containers in parallel, if their order and group are the > same?

The usual STOPPED => RUNNING or RUNNING => STOPPED time is < 1s, so no, we'll be doing that in serial order, but you won't really notice it because of how quick it's. That's assuming lxc.start.delay isn't set. If it's set, then obviously startup will take longer because we'll wait of lxc.start.delay before starting the next container (parallelizing would make the whole priority/delay idea completely pointless obviously). > Many thanx > Harri -- Stéphane Graber Ubuntu developer http://www.ubuntu.com
