I've got a small cut down XP Virtual machine, I originally used it with the free Virtual box player on 64bit Windows 10, I then transferred the VM to my Mac when I swapped and have since imported the VM into VMWare Fusion.

VM Ware fusion is very worthwhile if you're using an Intel Mac as it allows you to use a Bootcamp windows installation as a VM when booted to MacOS but still allows you to boot the same OS if you want Windows natively.

VMWare Fusion has fairly recently gone free for personal use which makes it very attractive, especially compared to Parallels Desktops sub mod.
