The minimal test simply boots Xen (built from previous build stages) and Dom0. The test needs a working kernel and minimal initrd for dom0. Instead of building our own kernel and initrd, which would mean maintaining one or two more builting scripts under automation/, we borrow a kernel and initrd from distros. For the kernel we pick the Debian Bullseye kernel, which has everything we need already built-in. However, we cannot use the Debian Bullseye initrd because it is 22MB and the large size causes QEMU to core dump. Instead, use the tiny busybox-based rootfs provided by Alpine Linux, which is really minimal: just 2.5MB. Note that we cannot use the Alpine Linux kernel because that doesn't boot on Xen.
