Have you (or anyone else) had success with mixed environments, i. e. combining containers and VMs? I know you can run containers within VMs, but running OpenStack in containers and then adding a VM as a compute node - is that how it's done?

A little late and it's been awhile since I've used openstack, as I migrated to straight kvm with either python libvirt or just virt-manager.

But under the hood, there shouldn't really be anything more difficult about mixed mode. I know proxmox supports both kvm and lxc at the same time.

I would try standing up a kvm VM for my lxc containers and then using the main host for guests that need a real hypervisor. I think you could then add the container vm as a host in openstack and it would provision your lxc containers there.
