Depends on what you do. As you are emulating a full OS- it needs the full ammount of memory requitred for its job. For example- Windows runs best with at least 32M, so I would give a VM running windows 32M. How does it allocate memory? I havnt run VMWare in a while, but seems to me it just took the full chunk of requested memory out of the host memory, and allowed the guest OS access to it. Someone correct me if I am wrong.
