"VMWare is virtual machine software that lets you run multiple operating systems on a single-processor x86 machine. We talked with VMWare's cofounder and chief scientist, Mendel Rosenblum about VMWare's technology, users, and applications...."

"Sims: You know, it's interesting that you mention the slowdown. I have heard that it takes quite a bit of memory to VMWare. Is that your feedback also? How much memory do you recommend on, say a Linux running on a Pentium box?"

"Rosenblum: Well, I think the minimum memory you would even probably consider doing this is 64 megs and it runs very comfortably in a 128 megs. So we recommend is put as much memory as you can on your machine, but we have people write us all the time saying "I'm running with 64 megs and it's enough." The issue is that, you know, you're running this whole new environment with the applications. It will still run if you don't have the memory, enough physical memory on your machine, it's just that you end up having to go to disk and that can slow you down tremendously. The minimum requirements to actually run the software is even lower than 64 megs it's just that end-user experience, your disk light would be on most of the time, you'd be sitting there waiting for the disk."
