Understandably, I was burning with a desire to upgrade the Windows 10 virtual machines in my Testlab to the latest and greatest from Microsoft. To my dismay, my old Asus G771JM Arch Linux-powered host did not meet (by a long shot) the highly artificial requirements to run Windows 11.
With the latest Red Hat release I experienced an issue with increasing the screen resolution above 1027×768. After checking out the VirtualBox forums, I found my answer and a solution to the issue.
