Vanilla version of Xen. Uses forks of Qemu and Seabios bundled
with Xen. This gives vanilla experince, but wastes space and
build time: typical NixOS setup that runs lots of VMs will
build three different versions of Qemu when using this (two
forks and upstream).

Slimmed-down version of Xen that reuses nixpkgs packages as
