  • List system level packages (works only of a full Guix system):
        guix packages --list-installed --profile=/run/current-system/profile

Additional channels

In ~/.config/guix/channels.scm:

  (name 'nonguix)
  (url "")
     "2A39 3FFF 68F4 EF7A 3D29  12AF 6F51 20A0 22FB B2D5"))))

Run Guix in VM

qemu-system-x86_64 \
   -nic user,model=virtio-net-pci \
   -enable-kvm -m 2048 \
   -device virtio-blk,drive=myhd \
   -drive if=none,file=guix-system-vm-image-1.4.0.x86_64-linux.qcow2,id=myhd

Install Guix in VM

gpg --verify guix-system-install-1.4.0.x86_64-linux.iso.sig
# Ako nemam GPG javni ključ
wget -qO - | gpg --import -

# Copy on a USB stick
dd if=guix-system-install-1.4.0.x86_64-linux.iso of=/dev/sdX status=progress

# Run in VM
qemu-img create -f qcow2 guix-system-igord.qcow2 50G
qemu-system-x86_64 -m 1024 -smp 1 -enable-kvm \
  -nic user,model=virtio-net-pci -boot menu=on,order=d \
  -drive file=guix-system-igord.qcow2 \
  -drive media=cdrom,file=guix-system-install-1.4.0.x86_64-linux.iso
  • Follow installation instructions.
  • After the installation is complete run the image in VM as described in a previous node.
          qemu-system-x86_64 -m 1024 -smp 1 -enable-kvm \
          -nic user,model=virtio-net-pci -boot menu=on,order=d \
          -drive file=guix-system-igord.qcow2
  • System config is in /etc/config.scm. To change configuration run:
      guix pull
      sudo guix system reconfigure /etc/config.scm

See the manual.

Mount local folder inside QEMU

qemu-system-x86_64 -m 2048 -smp 1 -enable-kvm \
-nic user,model=virtio-net-pci -boot menu=on,order=d \
-drive file=guix-system-igord.qcow2 -virtfs local,path=/home/igor/repos/config/guix/,security_model=passthrough,mount_tag=host0,id=host0
  • Inside the guest:
          mkdir config
          sudo mount -t 9p -o trans=virtio,version=9p2000.L host0 ~/config

Running Guix Shell

guix shell --container python coreutils procps grep less util-linux bash -- bash
  • or simply:
          guix shell -e '(@ (gnu) %base-packages)'
  • or with isolation just to the current folder:
          guix shell --container -e '(@ (gnu) %base-packages)'

Interesting install config with non-free stuff

Configure new system inside QEMU from Arch

  • Configuration in ~/repos/config/guix.
  • Mount the folder inside QEMU and run the image.
  • Reconfigure with sudo guix system reconfigure ~/config/system.scm

Copy paste with QEMU

Use sway/wayland inside QEMU

  • Interesting try. It kinda works.
          qemu-system-x86_64 \
          -m 2G -smp 1 -enable-kvm \
          -nic user,model=virtio-net-pci \
          -boot menu=on,order=d \
          -drive file=guix-system-igord.qcow2 \
          -virtfs local,path=/home/igor/repos/config/,security_model=passthrough,mount_tag=host0,id=host0 \
          -device intel-hda \
          -device hda-duplex \
          -device virtio-vga-gl \
          -display gtk,gl=on
