NOTE: answers are working on the assumption that you are trying to
deploy the charms on the local provider using LXC.

The nova-compute and quantum-gateway charms can't be deployed into LXC
containers using the Juju local provider as the container is limited
in what it can do; both of these charms will want to manage network
resources and compute wants to interact with the hypervisor, neither
of which will work with LXC in its default, out-of-the-box configuration.

Using KVM as the container technology will work you through this issue
(as running nested is generally OK).  However, you will need a second
network interface on the quantum-gateway node; so its still fiddly!

Also note that the OpenStack charms themselves do support using LXC as
the virtualization choice instead of KVM - this is a configuration
option in the nova-compute charm - but this is different to running
OpenStack itself under LXC.
