This repo provides a nix flake for automating the setup and running of 9front virtual machines. Virtual machines are run using qemu and connecting to them is done with drawterm.
These are made as a sort of demo, to reduce the friction for trying out the system without needing to futz with qemu and configuration. They are not (really) intended to be used generally for running 9front servers, but may serve as a good starting point for those interested in doing so.
The vms are configured in a way where a read only "parent" qcow2 is kept in the nix store and used as the backing file for the writable COW image. As such a first time setup needs to be run to create this new writable qcow2 image first.
nix run github:majiru/9front-in-a-box#setup-vm
Will download the source qcow2, configure it and place a
9front.amd64.qcow2 in to the current directory. Because
the parent is read only and kept around, if for some reason
you have imploded your disk you may rerun the setup without
needing to redownload and configure the parent qcow2.
nix run github:majiru/9front-in-a-box#run-vm
Will then start the new virtual machine and run drawterm to connect to it. The password for glenda is 'password'.
Instructions for using rio for first timers may be found in the 9front FQA.
This flake also provides scripts for using cwfs instead of hjfs and also is capable of running the arm64 virtual machines of 9front as well.
These different configurations are exposed via different packages, the convention
is setup-vm-$FS-$ARCH and run-vm-$FS-$ARCH. So to run a cwfs arm64 install you
may use run-vm-cwfs-arm64.
Drawterm is the graphical program used to connect to the virtual machine.
This flake will use a copy of drawterm from nixpkgs that is built for
X11 and pulseaudio. Nixpkgs also contains a drawterm build (drawterm-wayland) for wayland
and pipewire. The drawterm binary used by run-vm may be changed by passing a -dt flag.
# Use the wayland drawterm
nix-shell -p drawterm-wayland
# or with nix shell
nix shell 'nixpkgs#drawterm-wayland'
nix run 'github:majiru/9front-in-a-box#run-vm' -- -dt drawterm
