Experimental: virtualisation with Xen on GNU Guix
This is for x86_64. It requires familiarity with GNU Guix, and virtualisation.
Here, this is the list of packages for GNU Guix that are at an early stage and that could be looked at like this:
guix environment --load-path=./here --ad-hoc xen-0-tools guix environment --load-path=./here --ad-hoc xen-0-docs guix environment --load-path=./here --ad-hoc xen-0-boot guix environment --load-path=./here --ad-hoc xen-0-qemu guix environment --load-path=./here --ad-hoc grub-hybrid-xen
guix environment --load-path=./here --ad-hoc xen-0-busybox guix environment --load-path=./here --ad-hoc linux-for-x501u guix environment --load-path=./here --ad-hoc linux-firmware-for-x501u
The GNU Guix package xen-0-boot provides the hypervisor to start the Xen Dom0. A snippet for
a grub.cfg might look like this:
multiboot2 /gnu/store/...-xen-0-boot-.../boot/xen.4.12.1.gz module2 /gnu/store/...-linux-libre-.../bzImage ... module2 /gnu/store/.../initrd.cpio.gz
The tool that the grub-hybrid-xen package provides can make a bootloader which may be used as the kernel
for a Xen DomU and start a machine that is instantiated as a GNU Guix --full-boot VM image. (Other
disk images may also be used to create such a virtual machine.)
Package xen-0-tools gives the tools to start the Xen daemons, and to work with the domains of
the virtual environment.
Here is a shell function that may start the necessary daemons.
d___ ()
{
local D="xen-0-tools: init.d/xencommons [start|stop|...]";
local a=$( dirname $( dirname $( readlink -e $( which xl ))));
sudo $a/etc/init.d/xencommons ${1:-start}
}
