    Reload systemd: systemctl daemon-reload

    Get a list of your VM's VBoxManage list vms:

$ VBoxManage list vms
"Ubuntu" {1ba32309-d4c4-420a-a9c8-a38177f00bc4}
"Windows" {573df054-0e33-4389-896a-1234f10e25ad}

    Use the name returned in step 3 to manage the VM via systemd. For example, to manage the "Ubuntu" VM you would run:

sudo systemctl start vbox@Ubuntu     # Start the VM
sudo systemctl enable vbox@Ubuntu    # Start the VM on boot
