Virtualization Ahoy!!.

Looking at a lot of info about Virtualization, and especially Microsoft Viridian, I see there are various twists and turns to the whole issue..

PROS..

Same Hardware but multiple software roles.. Imagine Print Server, File Server, RADIUS Server etc all on the same machine but on different OSes.. So any admin repair to the File Server that needs a re-start or suspension of the service wont affect the other services.

CONS..

At the same time, the hardware proves to be a single point of failure. what if the parent OS goes down??
