Two were file servers that replaced two physical machines that had
hardware failures and rather than re-map login scripts etc it was easier
to just setup a virtual server and restore the data to that. A couple of
hours downtime was all that was needed for normal service to be resumed.
One is running a specific application and to be honest even with all
four in constant use I have barely seen the CPU usage go beyond 25%
Not only that, as I had no choice but to use NT4, a vritual machine was
the perfect solution since the NT4.0 isn't a supported operating system
on the new hardware. So it is a nice solution if you need to run some
legacy servers.
