People seem to be thinking that Xen is only for sharing
a colo machine with somebody else. But it could just as
well be used for one organization to isolate each major
application to a single virtual server, i.e. email server,
general web server, wiki server, hot web app server,
Asterisk server, etc. This way, when one of the applications
justifies its own server, migration is somewhat simpler
because it is not entangled with other applications.
Now that is what I have in mind. For me this is esp important where I have something nasty like a guy hosting a bunch of forums that are always not getting updated and getting defaced or worse. Until now I have had a dirty machine for stuff I know could lead to problems like that. But that brings up another question, how far isolated are different instances from each other really?
