Comment 6 for bug 1823309

This config item is found on nova_compute_context.py, "ctxt['live_migration_uri'] = 'qemu+ssh://%s/system'".

If we use the "libvirt-migration-network" config setting via juju we do get livemigration using the 'correct' url, as the nova.conf contains live_migration_inbound_addr which is updated to the correct new address. However, due to https://bugs.launchpad.net/charm-nova-compute/+bug/1860743, the ssh key exchange is not complete for connections targeting that address.
