OK - I'm relatively new to LXC (couple of months), I also use Debian not Ubuntu, but to me, it looks like your container is executing a whole bunch of init-scripts that it shouldn't be executing. (or really doesn't need to) In my containers, I just have /etc/init.d/rcS with nothing more than a line to create a default route (as the network is already created with lxc-start). The line exec /etc/init.d/rc S is commented out. That's the ones in Debian that'll normally do stuff with hardware like activate swap, fsck, etc. > Also - lxc looks exactly what I want to isolate some app servers into > individual units.

I've jumped in at the deep end - did a lot of local testing myself including running 50 containers on an old server, starting/stopping, running applications, etc. each running a standard LAMPy type thing - and Asterisk... And was happy enough with it to start to migrate a lot of remote hosted servers over to it, and have decided to build all my server from now on with containers in-mind.
