Create an Ubuntu VM with desktop using LXD provider in Terraform

[Tony Arnold]

Hello All,

If there are better places to ask this, then please let me know.

I'm using Terraform to create a virtual machine using the LXD provider.
I'd like to the VM to have a desktop environment so I can use it to
test a PyQt application.

I can create such a VM using the lxc CLI with this:

lxc launch images:ubuntu/noble/desktop ubuntu --vm -c limits.cpu=4 -c limits.memory=4GiB --console=vga

but I'm trying to figure out how to do this in Terraform with the LXD
provider. I currently have this to specify the image I want to use:

resource "lxd_cached_image" "envtest" {
  source_remote = "ubuntu"
  source_image = "noble"
  type = "virtual-machine"
}

Taking a clue from the CLI example above, I tried changing the
source_image entry to "noble/desktop" but that failed with this:

Failed getting image: The requested image couldn't be found for
fingerprint "noble/desktop"

I've googled this but not found any answers. Has anyone on here got any
ideas either how to fix this or where I can look to find an answer?

All help gratefully received.

Regards,
Tony.
