No, this is from rpi4 board (4GB), not qemu. The CI is a little
complicated here, lava boots the board with the new kernel and will
then trigger the openQA job. openQA will then connect to the board
using vnc to test the desktop. This is the last link that I sent to
Linus when he asked for it.

And this is the lava job for today -

Its the default ubuntu config. I can send you the config if you want.

Like I said, its not on qemu.

I am using the official ubuntu image downloaded from
https://cdimage.ubuntu.com/releases/21.04/release/ubuntu-21.04-preinstalled-desktop-arm64+raspi.img.xz
