While downloading the latest versions of Boinc, I saw that we now have the choice between Boinc and Boinc + VirtualBox. It's not clear to me what this VirtualBox is.
Does PrimeGrid use it for anything useful?
Can we do anything useful with VirtualBox if we are only crunching for PrimeGrid?
Or is it just another piece of software that will eat up memory and performance?
