Does anyone have any pointers on how much real memory and swap should be allocated to a linux guest for Websphere applications. We are running 500 mb real memory and about 1.1GB of swap. -Cameron

Wow! You've gotten some great responses already. Clearly, you need to think about your workload before anything else. You don't want to say "z/VM is better" and then throw a virus-scanning e-mail service on it and watch the thing tank because of CPU load. * the INTeL (and copycat) chip doesn't virtualize itself as well as the zSeries processor, so you get what I call higher "insertion loss", more of a hit relative to native performance when running PC software in a virtual machine * z/VM scales up better than VMware (probably related to the first point) * VMware controls are GUI oriented (but they do now have some early automation tools) * z/VM is HIGHLY automatable, configurable, and customizable but is (3270 and EBCDIC) really foreign to Windows people Cameron's report will be interesting, if they can share that. And what Adam and others have said is right on. Let me also play the opportunist and mention FreeVM-L. It is a LISTSERV discussion list for talking about things like this. Originally, the "free" part of the name was to indicate the goal of having an open standard for describing virtual machines, and that's still the central point of the list. But questions like yours are also the kind of thing we want to deal with there.
