Sun Microsystems 3.0.0 user manual

4 Guest Additions

In addition to establishing the general mechanism of reading and writing values, a set of predefined guest properties is automatically maintained by the VirtualBox Guest Additions to allow for retrieving interesting guest data such as the guest’s exact op- erating system and service pack level, the installed version of the Guest Additions, users that are currently logged into the guest OS, network statistics and more. These predefined properties are all prefixed with /VirtualBox/ and organized into a hier- archical tree of keys.

Note: Currently this information is only available with Windows guests.

Some of this runtime information is shown when you select “Session Information Dialog” from a virtual machine’s “Machine” menu.

A more flexible way to use this channel is via the VBoxManage guestproperty command set; see chapter 8.24, VBoxManage guestproperty, page 124 for details. For example, to have all the available guest properties for a given running VM listed with their respective values, use this:

$VBoxManage guestproperty enumerate "Windows Vista III"
