Multiple Partitioned Kernels

[Young, Mike]

I know about IBM VM (we used to run it at work), and I used to run a little MSDOS partition manager named doubledos back in the 80's (gave me two 286's when I ran a BBS - very useful for managing files while the BBS was running).  I'm sure many of us remember DesqView (sp??) from around that same time as well.  But I haven't seen it done on Linux.  Does anyone have a reference they could point me to?

Thanks,
Mike.

I would tend to believe your friend.

IBM has been running virtual machines for over 30 years.  A VM is 
independent of each other instance on one computer, and each runs it's 
own kernel, in its own memory space and namespace.

DEC also ran their version of VM, though I'm not sure it ever made the 
big league debut.  The concept has been around for a long, long time.

This was back before the days of VMWare, Xen, and the like.  I'm having a hard time believing him, but hey - it's Linux - and most things are possible with it.  I haven't had a chance to discuss it in depth with him.
