So I've attempted configuring a new VM with a cloud-init drive, and just using the basic options in the UI for the cloud-init config (user, pass, DNS, SSH key, upgrade packages, IP info).
I'm using an Ubuntu 24.04 cloud image. I've tried changing the boot order. Nothing works. I'm officially stumped.
