title: Is it possible to create Portable VM?
body: <p>I want to know that is it possible to create a fully portable virtual machine using any of the VMWare like products? My objective is to create a virtual machine (XP as guest OS), install some app in it, put the vm in a usb2 drive (performance is not a matter), and run it in any windows os (xp, vista, 7) without installing anything in host, using any host account (admin, guest, limited).
  Is it possible to do that using any vmware like product? If possible then which one is my best bet?</p>
