xen is a tool that enables one to run several virtual computers on one
real computer. For example, I can boot the Xenified kernel for F8 and
the run Windows on that (with newer CPUs).

The grub configuration specifies Xen as the kernel, then has two modules
title Scientific Linux SL (2.6.18-8.1.15.el5xen)
        root (hd0,0)
        kernel /xen.gz-2.6.18-8.1.15.el5
        module /vmlinuz-2.6.18-8.1.15.el5xen ro
        module /initrd-2.6.18-8.1.15.el5xen.img

I've used my 64-bit F8 system to run a couple of 32-bit Debian systems
for special purposes, and tried some things with Windows.

I have not used VMWare so I cannot comment on its  performance. I did a quick google search on VMWare  vs. Xen  and got a few hits  but most look like opinion pieces.  I am just starting to use virtualization with Fedora and i installed the Xen kernel and wasn't to impressed with the performance of the virtual machine(winXP). At this point I am not sure why it was so sluggish. It could have been something I did or didn't do. I know there is a mailing list for fedora virtualization stuff (that's not the official name) but I haven't found the time to play with it much so please add a grain of salt to my pronouncements. In the coming weeks i will be getting into it alot more and will have more info. If we can keep the thread alive then I will report back here. What has your experience with VMWare been?
