Do not touch Virtual Box with a barge pole.
I have never met such rude, obnoxious , head up their own *** forum moderators and members in my whole life!
I tried it, had a few issues, went to the forums, and wish I'd never heard of Virtual Box.
VMWare forums members are far nicer, friendlier, and more helpful!
Virtual Box = Nothing but trouble & rudeness!
VMWare = Easy, peasy, lemon squeezy!
You only want to run a virtual XP to unlock mobile phones, you're not running the Kenedy space centre!
Of course YMMV, but personally I'd avoid them like the plague!
