How to install VirtualBox Guest Additions – Tutorial
I guess (just like any user of a Processing Virtualization solution) I experienced problems with time synchronization within my guest OS. I searched the web for that, and I came across the above article. In the VirtualBox context “Guest Additions” is the term. I wasn’t able to find the right hints on VirtualBox.org, but the above article pointed me to “Devices > Install Guest Additions” within the menu of the guest VM app. That brought a superb quality improvement, including the resizability of the guest VM app window. I really love that.
