It seem pretty trivial to use Libvirt to manage LXC containers in addition to VMs, e.g. https://gist.github.com/scottslowe/7647800, so I think adding these is useful.

There are a few things to work out:

How PVC should treat these (still call them "VM"s? Make a new category?)
Whether Libvirt can live-migrate containers between hosts (is this a thing?).
How to do storage so that RBD is leveraged rather than host files.
How to handle multiple virtual networks.
How to provision LXC containers (lxc-create only way?) using the provisioner.

I think this should probably be a new API category/CLI group lxc rather than treating them exactly like VMs.
Seems like it is possible. This study investigated timing https://www.diva-portal.org/smash/get/diva2:1085809/FULLTEXT02.pdf and seems to indicate this is possible, but would need to be tested.

3-5 would need to be investigated.

Did more investigation, and this seems to be a pretty involved change that's quite a bit out of scope. Going to close.
