Docker virt-manager

GTK Broadway web UI for libvirt

What is it?

virt-manager: https://virt-manager.org/
broadway: https://developer.gnome.org/gtk3/stable/gtk-broadway.html

Features:

• Uses GTK3 Broadway (HTML5) backend--no vnc, xrdp, etc needed!
• Password/SSH passphrase support via ttyd (thanks to @obazda20 for the idea!) Just click the terminal icon at the bottom left to get to the password prompt after adding an ssh connection.

• Dark mode

Requirements:

git, docker, docker-compose, at least one libvirt/kvm host

Usage

docker-compose

If docker and libvirt are on the same host

services: 
  virt-manager:
    image: mber5/virt-manager:latest
    restart: always
    ports:
      - 8185:80
    environment:
    # Set DARK_MODE to true to enable dark mode
      DARK_MODE: false

    # Set HOSTS: "['qemu:///session']" to connect to a user session
      HOSTS: "['qemu:///system']"

    # If on an Ubuntu host (or any host with the libvirt AppArmor policy,
    # you will need to use an ssh connection to localhost
    # or use qemu:///system and uncomment the below line

    # privileged: true

    volumes:
      - "/var/run/libvirt/libvirt-sock:/var/run/libvirt/libvirt-sock"
      - "/var/lib/libvirt/images:/var/lib/libvirt/images"
    devices:
      - "/dev/kvm:/dev/kvm"

If docker and libvirt are on different hosts

services: 
  virt-manager:
    image: mber5/virt-manager:latest
    restart: always
    ports:
      - 8185:80
    environment:
    # Set DARK_MODE to true to enable dark mode
      DARK_MODE: false

      # Substitute comma separated qemu connect strings, e.g.: 
      # HOSTS: "['qemu+ssh://user@host1/system', 'qemu+ssh://user@host2/system']"
      HOSTS: "[]"
    # volumes:
      # If not using password auth, substitute location of ssh private key, e.g.:
      # - /home/user/.ssh/id_rsa:/root/.ssh/id_rsa:ro
