I should add a highly recommended alternative to using VirtualBox is virt-manager. Some very hard working OM contributor was kind enough to put this how to article in our Forum Resources section:
How to install and use virt-manager
I do not mean to be telling other people what to do, I describe what I do in case other users find it helpful. I use virt-manger in my Cooker hardware system. I use VirtualBox 7.1.8 in my Rome hardware system. I do not do much work in Rock, that is mostly for testing or sorting out user reported problems specific to Rock.
