udevadm device info and DBus UDI of devices

The get the freedesktop UDI (Unique Device Identifier) of a device, forget about hal, lshal, hal-find-by-property etc, as HAL is long deprecated!

Use the DBus instead. The easiest way to use DBus without having to type a gazillion of commands is to use the qdbus command (or qdbusviewer for a GUI, but a gui won't make things any easier unless you want to navigate through different options):

To get a list of the available freedesktop (because we grep for it) system services (i.e. services provided by the operating system and also by any system daemons):

$ qdbus --system | grep freedesktop
 org.freedesktop.systemd1
 org.freedesktop.Avahi

org.freedesktop.NetworkManager

Necessary scripts and procedure to start libvirt VMs in a provided order, with an given delay before starting each subsequent VM.

  1. Ensure that your VMs can shutdown gracefully when the power-button is pressed.

  2. Place the file vm-boot-order.py in /opt directory

  3. Make it executable: chmod +x /opt/vm-boot-order.py

  4. Check that the script starts and shuts down your VMs as expected. The script can be executed as follows:

     /opt/vm-boot-order.py start
 /opt/vm-boot-order.py stop
 /opt/vm-boot-order.py status

  5. Make a systemd service to execute the script when booting or shutting down the hypervisor:
