I’m trying to get this going before hammering on real hardware. First gotcha – yes, probably my fault, again, but I’ll mention it: if you run
sudo apt-get purge -y *lxd* *lxc*
then it removes maas-3.5! Now that was… unexpected. In fairness the page does say to run that if you’re on an old version of Ubuntu, and I’m not, but still.
In the LXD init stage, there’s a reference to
Name of the existing bridge or host interface: br0 - br0 is the name of the bridge the user configured (see sections above) which is connected to a MAAS-managed network.
but I don’t see where setting up br0 is actually discussed. If I’m just overlooking something obvious please feel free to point it out.
