Launch QEMU Virtual Machines with LXD

Since version 4.0 LXD also natively supports virtual machines and thanks to a built-in agent, they can be used almost like containers.

lxc image list images: | grep VIRTUAL-MACHINE

lxc launch images:ubuntu/21.04 vm2104 --vm
lxc launch images:ubuntu/21.04/cloud vm2104c --vm
