If you provide me with an example (and some description of

lxc-create -n ubuntu -f ~/mynetwork.conf -t ubuntu

I'm not there yet, but found something interesting. If lxc-checkconfig
reports full green, clone(NEWNS|NEWUTS|NEWIPC|NEWPID|NEWNET) in
lxc-start shouldn't fail. Who's wrong here?
Cheers,

$ lxc-checkconfig
Kernel config /proc/config.gz not found, looking in other places...
Found kernel config file /boot/config-2.6.26-2-686
2.6.26 ? Mmmh, You need at least a 2.6.29 for a system container (better
to have a 2.6.32).

Bah ! Looks like the lxc-checkconfig is buggy (fix in attachment).
