I'm still wondering why there's nothing to take advantage of these  
multi-core processors to allow someone to run multiple oses  
simultaneously using one core for each os.  No reason you can't use  
task switching, and run dos, windows, linux, and others all on the  
same machine, simply dropping each os on it's own processor, and  
letting it loose.  No need for emulation, and no need to virtualize  
anything (except possibly the video) since keyboard input wouldn't be  
an issue unless you switched specifically to that cpu.
I'm really puzzled why such a system doesn't exist.
I haven't a clue how such a thing could/would be implemented, but it's  
obviously possible, so why hasn't it been done?
I realize there's not a huge demand for multiple oses on a single  
machine, but having linux/windows on the same pc, each booting from  
it's own hd, using it's own cpu, and not interfering with the other  
operating systems on the computer would be a huge boon for some, since  
there'd be no emulation required, no virtualization, and 100 percent  
native code execution.
I think some of the bare metal hypervisors come close to this  
implementation, but they still have emulation layers instead of  
granting direct cpu access, so they don't really fit the bill.
