juju boostrap to lxd fails

[james beedy]

Freshly provisioned vm, snap installed juju and lxd, ran lxd init, try to bootstrap localhost with juju and get:

$ juju bootstrap localhost
ERROR profile "default": no network device found with nictype "bridged" or "macvlan"
 the following devices were checked: eth0
Note: juju does not support IPv6.
Reconfigure lxd to use a network of type "bridged" or "macvlan", disabling IPv6.

Looking in the lxd default profile I see:

devices:
  eth0:
    name: eth0
    network: lxdbr0
    type: nic

I was able to bootstrap once I modified the default profile to reflect:

devices:
  eth0:
    name: eth0
    nictype: bridged
    parent: lxdbr0
    type: nic

Looks like this may be on the lxd side of things, so tagging lxd.

$ lsb_release -a

$ juju --version

I submitted this bug a while back. I thought we already had a 2.7 fix for it

This is odd.

We had this come up already, see:
https://bugs.launchpad.net/juju/+bug/1867886

My own LXD profile looks like the first you listed, from when I was testing. It still works fine.

However, when I tried installing LXD 4.0 on a fresh machine, the profile was in the traditional form after "lxd init". I then tried installing from the 3.22 channel (where we first saw this) and it now also creates in that form. Furthermore, LXD prevents attempts to change it to the new one.

I've sought info via the Canonical LXD IRC, but nothing is forthcoming so far.

OK. Replicated.
