After a build configuration is complete, I want my unit test configuration to be triggerred in such a way that 3 jobs start on 3 different operating systems (Linux, XP and Vista). I have several agents of each of these operating systems. I want only one instance to run on Linux and one on XP and one on Vista. Currently, I am thinking of creating 3 configurations to achieve this - but that seems like a waste. I want just one configuration to be triggered on one of Linux, XP and Vista.
The marketing docs seem to indicate that this is possible - but I could not figure this out from the UI. May be I am missing something simple.
