With the latest MAAS and Juju releases (available for 12.04 from the Cloud Tools archive), its possible to mix LXC containers with physical servers to support your OpenStack deployment on a smaller number of servers. Its possible to run the following charms in LXC containers:
- cinder (so long as you are using a Ceph backend)
Once you have deployed the charms that need physical servers (nova-compute, quantum-gateway, ceph and swift-storage), you can add LXC containers to specific machines:
juju add-machine lxc:1
The example above will create a LXC container on physical machine 1.
You can then target a charm to a specific LXC container - for example:
juju deploy --to 1/lxc/0 nova-cloud-controller
Deploys nova-cloud-controller to the first LXC container on physical machine 1.
We have some work currently pending final testing that will allow you to deploy ceph/swift-storage and nova-compute on the same physical machines - allowing you to have shared storage/compute servers within your deployment.
