In situations like this, we usually write a script that changes
virtual IPs or other configuration details between the tests and then
reboots the boxes. If you are using Unix, take a look at "expect"
command that is very handy when talking to other devices/interfaces
with deterministic behavior (such as a configuration interface of a
switch). There might be a similar tool for MS Windows (as a part of
Visual Basic package?), not sure.

If you can avoid changing virtual IPs and other things outside of
Polygraph, then you can run a single test with multiple phases; one
phase per one request rate versus average response curve point.
