Greetings, For testing purposes, we need to place Windows 2000 Server, Linux RedHat 9, RedHat Enterprise Linux 3 AND Fedora 1 on ONE server. We want to easily switch from one OS to another OS on the same machine without rebooting. Our questions are: 1. Does any one know any Virtual Machine Application out there that we can use (other than VMWare)? 2. Does any one use VMWare for RedHat Enterprise Linux 3 AND Fedora 1? VMWare does not list RHEL 3 and Fedora 1 as supported OS. Best regards, Ibnu.
