Right now in ubuntu precise, it's

    lxc-create -t ubuntu -n p1
    lxc-start -n p1


    lxc-create -t ubuntu-cloud -n p1
    lxc-start -n p1

If you want to deploy a bunch of cloned images, you can

    lxc-create -t ubuntu -n plain -B lvm
    < customize /dev/lxc/plain image if you like >
    for i in `seq 1 20`; do
        lxc-clone -s -o plain -n p$i

The only things different in Ubuntu are that a lxcbr0 bridge gets
installed by default (*1), and the release has been tweaked a bit so no
changes are needed to run in a container.  The first can't really
be done in lxc.git (because it's distro-dependent), and the second
is of course independent of lxc.


(*1) and if you don't specify a configuration file at creation time,
a default one using lxcbr0 is used.
