Background: I'm trying to get Openstack working with Juju. I'm testing it, so I either have to use KVM virtualization or LXC because I only have one (powerful) machine. I would prefer to use LXC because it's lighter and faster. But some openstack charms need to format /dev/sdb or insert a kernel module or mount a drive, and will fail to deploy in LXC.
So, is it possible to deploy some Openstack services in LXC and some on KVM virtual machines that are managed by MaaS and add relations between them?
