document how to run a quick test via qemu / incus

[leggewie]

sudo apt install ovmf qemu-system-x86
wget https://dl.armbian.com/uefi-x86/Noble_cloud_minimal-qcow2
qemu-system-x86_64 -bios /usr/share/ovmf/OVMF.fd -m 2048 -display gtk,gl=on -device virtio-net,netdev=net0 -netdev user,id=net0,hostfwd=tcp::5800-:22 -drive if=none,id=root,file=./Noble_cloud_minimal-qcow2,format=qcow2 -device virtio-blk,drive=root

success!

not sure where this should go in the docs, so opening a ticket instead for now.

maybe good to explain the various switches just a little bit.

I'm open to using any of the other virtualisation options, notably incus.

In close proximity, we should document how to produce your own qcow2 or other kind of images for this kind of testing.

Is any of this done yet to test for example at least "boots, has network and ssh (root:1234)" running correctly. That could be a nice unit test.
