Mike,
Sorry for the mixup... KVM's are used to switch between multiple
physical computers... for instance I have a laptop and three towers.
These are all stand alone machines that use the KVM so I don't need 4
monitors, 4 mice and 4 keyboards.
Xen on the otherhand lets you run multiple Virtual machines.... that is
you would use FEDORA as your main operating system and Xen would allow
you to have virtual machines. The Windows equivalent would be VMware to
create virtual machines.
If you have one box (ie computer) and you want to run multiple operating
systems two main choices to consider would be
1. as you pointed out Xen. But you should have a workhorse of a computer
to do that. Think of what the minimum requirements for XP and Fedora are
and add those requirements together than add 10%... that is how I would
think about it. Xen is a convenient way to run multiple operating
systems but not the most effecient. Virtual machines (such as created
through Xen) are bloated as you require the whole operating system (as
aposed to option 3). Virtual machines are often used by windows
developers and programers. if something messes up then they just close
the virtual machine instead of rebooting. I find it funny how window
developers use linux boxes to increase their productivity.
2. Do some research into using GRUB to setup a dual boot system so you
have a Fedora Partition and an XP partition. This means the system
resources are alocated sepratedly, but only one OS can run at a time. to
switch OS's means a reboot.
3. If you want to run Windows applications inside Linux then think of
researching Linux WINE... or take a look at Crossover office. these are
options to run your favourite windows application in a linux
enviornment. WINE is a runtime environment that clones windows and some
of its libraries. So fo instance you have a good copy of Adobe
photoshop, or dreamweaver or office XP, then WINE is your ticket to
using those. A virtual machine is verry bloated.
Mike... ask yourself what you need to run two OS's for... I came from a
full MS background and the only Windows thing I am still tied to is a
driver for my wireless card. As a digital photographer,professional
geographer, ski instructor and tech junkie I have found everything I
need in the open source realm. Think these decisions out carefully.
Cheers

A switck between computers but able to use one (K)eyboard (V)ideo and

For my setup between 4 computers I have one PS2 keyboard, one usb mouse
with ps2 adapter... and one monitor with SVGA
they all plu into a BOX... then when I double tap SCROLL LOCK followed
by numbers 1 through 4 I can switch between computers. For $20 I use a
generic brand that came with all the necessary cables and powers off os
ps2 ports. there is also a mnaul botton that I can use if keyboard
freezes.
Linux gets a little fritzy sometimes when I do a lot of switching and
moving around. the fix is a simple re-plug of keyboard usualy or mouse
if its realy bad.
This is a good setup if you are experimenting with several boxes or
fixing computers or just a geek.
if you are networking there is a network version you can use put out by
the people at realVNC.
Does that answer your question.

You see I need to be able to run Windows so I could use certain pieces
of software. That sounds very easy just being able to press scroll
lock and then change to another OS, I think that is what you are
saying?
Could I run Windows while using Linux using KVM or should I use Xen?
Which is faster? Is there a way to install either using yum? How do
they work?
