I've got a fairly complex script I use to fire up containers modeled largely on the OpenVZ model. The problem here is that you may want containers to start at boot and ones you DON'T want to start at boot. You may also have experimental containers you want set up and configured but will only started if you force them. You'll also discover that a little "load leveling" helps if you think you are going to fire up 3 dozen VM's all at once. You'll find out rapidly that it's not a good idea to just start everything blindly for a number of reasons. I have some parameters I add to the configuration files (commented out if running stock code) like this: lxc-boot.onboot = yes lxc-boot.disabled = no These correspond directly with the equivalent OpenVZ features. Then I have a script (which still needs a lot of cleanup) which will go through all the configuration files and start VM's. If it's started with a -b option (boot time) it will only start VM's that are set to: ".onboot = yes". If you run it manually, you can start one or more VM's but only if they are NOT disabled. A -f option will "force" firing up disabled VM's but only one at a time. When it starts a container, it dumps the output to a log file and forks it off as it's own process. The script use to use the iowait trick to restart containers and, now that's part of the base binaries, that's what needs cleaning up now. But this is all "high level" management stuff that needs to be looked at and decided upon. Maybe, one of these days, I'll finish cleaning it up and send it to Daniel. Regards, Mike -- Michael H.
