Strange behaviour of launching of ubuntu with cloud init with different pools

LXD
1

I have a strange situation on a system with two storage pools, when I launch installation with:

lxc launch -s one images:ubuntu/jammy/cloud test --vm -c limits.cpu=2 -c limits.memory=2GB -c cloud-init.user-data="$UC"

cloud-init is being run as it should, but when I use the other storage which is default:

lxc launch -s default images:ubuntu/jammy/cloud test --vm -c limits.cpu=2 -c limits.memory=2GB -c cloud-init.user-data="$UC"

cloud init is ignored and I can see in the log:

cloud-init.log:2023-01-29 16:09:32,065 - modules.py[INFO]: Skipping modules 'wireguard,snap,ubuntu_autoinstall,keyboard,apt-pipelining,ubuntu-advantage,ntp,timezone,disable-ec2-metadata,runcmd' because no applicable config is provided.

Could you please point me what can be wrong and how to debug it eventually?

($UC content is identical in both cases of course)
(both storage pools are on ZFS, on two different zfs pools)

Hi, @RandomUser,
Can you post the output of those commands?

lxc storage list
lxc storage show one
lxc storage show default

Regards.

I have another interesting observation, on both pools cloud-init works correctly when I launch the ubuntu-daily:jammy but in a container, not a VM, with the same cloud-init config on all instances as above.

OK, so following my previous post, instead of using images:ubuntu/jammy/cloud, I used to create a VM on both pools ubuntu-daily:jammy. It works as it should.

So my problem is solved, as there is no difference between functionality of both images for my purposes - but the images:ubuntu/jammy/cloud is definitely somewhat broken.

Yes, probably, fine you have solved the issue.

@monstermunchkin sounds like there maybe a cloud init issue in the distrobuilder ubuntu vm images.
