Wrong bridge selection at LXC creation/unable to choose

Hi, trying to clone or deploy a new LXC container on pre-LXC 3.0, the creation completes correctly since it still uses the lxc.network directives, but then container fails to start because the wrong bridge is selected. The creation process always sets br0 as the bridge for the container, even if default bridge is set to br1. br0 bridge does not even exists on host.

I don't have the option to choose which bridge to use at container creation.
