Quoting Steven Hatfield
VMWare doesn't require kernel mods, and will run several different x86 based OS's, including all versions of Windows, BeOS, Linux, and BSD. Probably some others that I can't think of right off of the top of my head. It is also much slower than Win4Lin is, running at roughly 1/2 of your native processor speed.
VMware runs at near native speed, if you have enough memory, at least 256MB. I now have 384MB and can run Win98 and FreeBSD 4.2 at the same time from within Linux. Starting both at the same time often leads to the virtual machines crashing. At 128MB memory, I had to train myself to push a button and wait until I saw it depress before releasing the mouse button. With more memory, no such problem. It was really impressive to just pop the FreeBSD CD-ROM into the drive and watch it boot and install without a hitch.
