I was doing some reading, and came across info that the EULA for Vista (Ultimate), specifically allows using the OS as both a host OS, and a guest OS inside a VM, on the same machine, with the same license. (*)
(*) If this is not correct, let me know.
I was just thinking, and trying to figure out how that would work to bootstrap a system such as that, using a retail upgrade copy of XP Home, and a retail upgrade Vista Ultimate DVD.
Since MS (allegedly) has closed the "hole" that allowed one to do a double-install with a Vista upgrade DVD, without putting XP on first, then that rules out being able to do this with just the Vista DVD (easiest solution).
So that would imply that one needs to install (and activate?) XP on the machine before installing Vista. The problem comes from needing two installs of XP, one on the host, and one on the guest. Conceivably, if you first installed XP on the host, and then upgraded to Vista, then you could re-install that same copy of XP (and activate?) it as the guest OS in the VM, before upgrading that OS to Vista Ultimate.
The big question seems to be, if you use a valid XP CD-key to activate XP, and then install an upgrade to Vista, does that invalidate that CD-key in MS's system, such that you are prohibited from using it to install again?
If so, this directly implies that in order to use a Vista Ultimate upgrade DVD to do dual (host + guest) OS installs, then you need TWO retail copies of XP to upgrade from. This means extra $$$, to take advantage of capabilities that supposedly come with Vista Ultimate.
If this is true, then I am a rather disappointed MS customer.
