I think I found the culprit. When installing from ISO it installs HWE
kernel.
LXD 5.21 LTS uses the Virtio GPU by default but the ubuntu:22.04 image
uses 5.15 generic kernel which does not have virtio_gpu driver

Title:
spice-vdagent seems not to be working in jammy when connecting from
noble
Status in spice-vdagent package in Ubuntu:
New
Bug description:
Steps to reproduce
1. Create LXD VM desktop-jammy on Ubuntu 24.04 (Noble) host
lxc init --vm ubuntu:22.04 desktop-jammy
2. lxc start desktop-noble
3. lxc exec desktop-noble bash
4. Install ubuntu-desktop metapackage
apt update
apt install -y ubuntu-desktop
5. Set passwd for ubuntu user
$ passwd ubuntu
6. Disable systemd-networkd-wait-online.service (otherwise it will wait for
timeout)
systemctl disable --now systemd-networkd-wait-online.service
7. Reboot
8. Connect to the vga console
lxc console --type=vga desktop-jammy
Wait for login screen to load
Expected result
The GDM login menu should appear
The actual result
The screen is stuck.
I saw that the daemon is not running

but still when I retry connecting to vga console the screen is stuck on
loading and shows nothing
When you check the systemd status it says
root@desktop-jammy:~# systemd-analyze
Startup finished in 428ms (kernel) + 7.285s (userspace) = 7.713s
graphical.target reached after 7.141s in userspace
When you try the same for ubuntu:24.04 all works as expected and you
also see the system logs on loading before seeing the Login screen.
