Bug Description

MAAS 3.0. Adding a LXD VM with 4 disks, 8 (boot), 32, 32, 8 G:
Pre commissioning, the 4 disks show up, except the boot disk specified during composure (sda) is on the first 32 GB drive (which is wrong). Total space for the machine shows 80 GB
During commissioning - the capacity drops to 8 GB for the machine, and only shows one drive.

Seems 100% reproduceable.

Hi, yes after upgrading LXD to latest (4.17 I believe), the issue went away with the disappearing disk.

And after upgrading MAAS to 3.1 beta, the correct boot disk was set. I don't know if we want to backport the MAAS fix.

The change has already been backported to 3.0, but not yet released. It will be once we release 3.0.1
