unable to find host bridge for space(s) "xxy" for container "0/lxd/0"

I'm trying to deploy OpenStack through Landscape. However, LXD container creation on nodes fail with the message unable to find host bridge for space(s) "xxx" for container "0/lxd/0".

The landscape logs are cryptic and don't really point me in any distinct direction:

Update: A manual installation via Juju models succeeds so this seems to be exclusively related to Landscape Autopilot.
