;; This is an operating system configuration template
;; for a "bare bones" QEMU setup, with no X11 display server.

;; To build a disk image for a virtual machine, do:
;;
;;     ./pre-inst-env guix system image --image-type=hurd-qcow2 \
;;         gnu/system/examples/bare-hurd.tmpl
;;
;; You may run it like so:
;;
;;     guix shell qemu -- qemu-system-i386 -m 2048                \
;;       --enable-kvm                                             \
;;       --device e1000,netdev=net0                               \
;;       --netdev user,id=net0,hostfwd=tcp:127.0.0.1:10022-:2222  \
;;       --snapshot                                               \
;;       --hda /gnu/store/...-disk-image
;;
;; and use it like:
;;
;;     ssh -p 10022 root@localhost
;;     guix build -e '(@@ (gnu packages commencement) gnu-make-boot0)'
;;
;; or even, if you build the image with at least --image-size=3G:
;;
;;     guix build hello
