Comment 14 for bug 1733882

@wpk

I'd like to get your confirmation that what we're seeing are the expected result and whether I need to file new bugs for 3, 4 and 5.

1. upgrading a 2.3.1 model to 2.3.2 doesn't fix LXD, neither on old nor new machines.
2. creating a new 2.3.2 model fixes LXD: the container network is now host-only (local).

3. container-networking-method=fan and fan-config=10.10.0.0/16=192.168.0.0/8 results in the error "failed to start machine 0/lxd/0 (unable to setup network: host machine "0" has no available FAN devices in space(s) ""), retrying in 10s (8 more attempts)"

4. container-networking-method=provider and an external network without IP address breaks the networking of both the host and the container.
5. container-networking-method=provider and only internal network breaks the networking of the container.
  This is with "promiscuous mode", "MAC address changes" and "forged transmits" allowed. If I look at the `ifconfig` output, it seems as if there is more wrong; the `lxdbr0` interface still has `10.0.187.1` as ip; as if the container network mode is "local"..
