Xen vs VMware

[Matthew Dillon]

:1) What is the difference beetwen Xen and VMware?
:2) What is the better choice: Xen or VMware?
:3) Why does it exist a project of porting for Xen on
:DragonFly, and why it doesn't exist the same project
:for VMware?

    VMWare is a machine emulator.  Operating systems running under VMWare
    think they are running on the actual hardware (generally speaking).

    Xen is an operating environment.  Operating systems running under Xen
    have to be aware that they are running under Xen.

    Generally speaking I prefer the VMWare concept over the Xen concept.
    Xen actually has to run two operating systems, one serving as the
    master and the other as the 'guest' OS, and this compounds the 
    number of potential bugs you might run into a lot more then a machine
    emulator does.
