I'm in the process of building a fairly hefty (4 cpu) 
workstation.  The intended use is primarily as a development 
workstation for heavily multi-threaded code, including 
significant amounts of opengl and other graphic/multimedia 
operations.  It would be convenient for me if I could virtualize 
a few of my existing systems and only keep the one piece of 
physical hardware running, but I don't want to compromise opengl 
or multimedia performance.  

I assume, perhaps falsely, that there would be a significant 
performance loss for those specific areas by running those 
tasks on a virtualized system.

>From what I understand of the Xen installation directions on 
xensource.com, you install the xen hypervisor like you would an 
operating system, and effectively ALL oses running on the machine 
are virtual.  

If the "xen host" can be the main workstation with access to the 
full power of the system, I will cheerfully virtualize a few 
older servers.  But if installing the xen hypervisor on the 
system means I won't get the benefits of (for example) 
accelerated opengl displays, that's a deal killer.  

Is it possible to run the xen hypervisor within a normal Linux 
distribution (preferably Debian)?
