The word "same" never occurs in the text, which never contemplates multiple installs.
It says you can't use it in a virtual machine. End of story. End of discussion.
Vista Business and Ultimate include
additional licenses to also run the
same licensed copy of Vista running natively on the licensed device in a virtualization environment as well.
In other words, if you purchase or build a PC with Windows Vista Ultimate, you can use that same installation and license to install it in a virtualization environment on that same platform. That goes beyond what has been done on any other platform for virtualization, and why the limitation is specifically delineated on Vista Home:
You may not use the software installed[1] on the licensed device[2] within a virtual (or otherwise emulated) hardware system.
[1] This means "the software" (i.e., Vista Home Basic or Premium) is
already installed on a licensed device.
[2] The "licensed device" is the device that Vista Home is
already installed on, and that license may not be reused to also install it in a virtualization environment, which you CAN do with Vista Business and Ultimate, because Microsoft includes additional licenses specifically for virtualization use, which is why there are all these specifics about virtualization use on the lower end Vista versions in the EULA in the first place.
The Vista Business/Ultimate EULA on the same topic states:
6. USE WITH VIRTUALIZATION TECHNOLOGIES. You may use the software installed on the
licensed device within a virtual (or otherwise emulated) hardware system on the licensed device. If
you do so, you may not play or access content or use applications protected by any Microsoft digital,
information or enterprise rights management technology or other Microsoft rights management
services or use BitLocker. We advise against playing or accessing content or using applications
protected by other digital, information or enterprise rights management technology or other rights
management services or using full volume disk drive encryption.
This is because Vista Business and Ultimate include
additional licenses so that you can use the
same copy, legally ALSO within a virtualization environment on that same system.
This is more than is possible with any other commercial OS, from a licensing perspective. The restrictions on Vista Home are ONLY restricting you from using it in a VM on the device where it's
already installed. If you buy Vista Home standalone as a retail box, and it's not installed anywhere else, you are free, legally and technically, to use it in a VM to your heart's content.
