Supported Agents Linux
This check uses VBoxControl to query the version and revision of the guest additions installed in a VirtualBox Linux guest. If no guest additions are installed at all, the check will get critical. if the version and revision of the guest additions do not match the version and revision of the virtual box host, the check will warn.

Discovery

One service is created on each Linux VBox host having guest additions installed(!). If you want to force the check on {all} of your Linux guests, you need to configure explicit checks using {checks=}.
