if you haven't tried OpenStack with LXC yet

First, thanks for all your notes because I'm learning OpenStack via
JuJu/Ubuntu myself.

I saw you mention:

>> I initially installed it in a VM, but there were some complex routing
>> issues with that, so now it's running on the main OpenStack host.

Your mention of VM didn't state whether that was KVM/Virtualbox etc but if
you've not experimented with LXC and OpenStack yet... take some time to.

Configure OpenStack for LXC
virtualization<http://docs.openstack.org/essex/openstack-compute/admin/content/lxc.html>

But JuJu makes this easy:

Configuring JuJu for "Local" (re LXC)
use<http://askubuntu.com/questions/65359/how-do-i-configure-juju-for-local-usage>

then use JuJu to deploy the OpenStack Charms.

I've been doing that for several reasons:

   1. Canonical provides a learning tool in the form of a Ubuntu Live-USB
   image that when booted from creates a full OpenStack environment using LXC
   that is great to learn how to operated/use OpenStack (although I don't
   think its persistent between reboots).
   2. With the coming support of Ubuntu on ARM next spring/summer and the
   fact that its already supported by ARM servers such as Calxeda... that will
   make an interesting Cloud environment for web services which is both
   inexpensive in CAPEX and OPEX (because of a 90% reduction in heat/energy
   use btwn ARM and x86).
   3. And that ARM 64 bit servers should start appearing late 2013 or early
   2014.
   4. JuJu supports deployment of OpenStack and the use of "local" re LXC
   virtualized environment

Since ARM doesn't have HW virtualization (yet) OpenStack can be used with
LXC instead on ARM without the overhead incurred by full hw virtualization.
