Unless those WinXP installations were made using an Academic ("For
Students and Teachers") License, then you were pirating two of those
installations, and were lucky enough to not get caught. (Civil fines for
copyright infringement can go as high as $50,000 per illicit copy,
should the copyright holder choose to enforce his legal rights.)

You need to purchase a separate Vista license for each computer on
which you install it. (As long as you have multiple identical licenses,
it doesn't matter if you use the same CD for the installations, as long
as you use a different license each time.)
Just as it has *always* been with *all* Microsoft operating
systems, it's necessary (to be in compliance with both the EULA and U.S.
copyright law http://www4.law.cornell.edu/uscode/17/117.html
), if not
technically) to purchase one WinXP license for each computer on which it
is installed. (Consult an attorney versed in copyright law to determine
final applicability in your locale.) The only way in which WinXP and
Vista licensing differs from that of earlier versions of Windows is that
Microsoft has included a copy protection and anti-theft mechanism,
Product Activation, to prevent (or at least make more difficult)
multiple installations using a single license.
> and if not, what do I do?
If you have Vista installed on two computers, then you need to own two
licenses. Do you? If so, then you needn't buy another license. If
not, then either buy another license, or remove one of the Vista
