systemd-nspawn - Airspy Mini (USB) in container


  • Fedora 26 host (Debian in container).
  • Find USB device and alias:
    # Bus and device number
    lsusb |grep Airspy
    Bus 001 Device 002: ID 1d50:60a1 OpenMoko, Inc. Airspy
    # Get device alias
    file /dev/bus/usb/001/002
    /dev/bus/usb/001/002: character special (189/1)
    grep 189 /proc/devices
    189 usb_device
  • Create plugdev group on host, GID must be the same on host and within container (ex. GID 46).
  • Create udev rule on host for USB device:
    cat /etc/udev/rules.d/airspy.rules 
    ATTR{idVendor}=="1d50", ATTR{idProduct}=="60a1", SYMLINK+="airspy-%k", MODE="660", GROUP="plugdev"

    sudo dnf install debootstrap
  • Install Debian in container:
    sudo debootstrap --arch=amd64 stable /var/lib/machines/debian
  • Create user, set root password and install dbus:
    sudo systemd-nspawn -D /var/lib/machines/debian
     useradd -d /home/$user -m -s /bin/bash $user
     passwd $user
     passwd root
     apt install dbus
     exit # or ctr-]]]

    sudo systemctl edit systemd-nspawn@debian.service
    ExecStart=/usr/bin/systemd-nspawn --quiet --keep-unit --boot --link-journal=try-guest --bind=/dev/bus --network-veth --network-bridge=virbr0 -U --settings=override --private-users=0 --private-users-chown --machine=%i
    DeviceAllow=char-usb_device rwm
  • Start container:
    sudo systemctl start systemd-nspawn@debian.service
  • Log in as root:
    sudo machinectl login debian
