Sometime on Feb 12, Harshal Vaidya assembled some asciibets to say:
if you run two distros on a dual cpu machine at the same time (one distro per cpu), you will need two separate swap partitions --
How will you do this? I've never heard of this thing. Logically thinking, at one time you will run one distro which will take command of both the CPU's (if its an SMP).
The point of two processors is that you can run two processes simultaneously, at exactly the same time. It has nothing to do with whether you have 1, 2 or 3 distros running simultaneously (time shared).
In fact, the more I think about this, the more I'm convinced that it's even possible to run multiple distros simultaneously on a single processor machine. All you need to do is segregate memory and swap correctly. I think IBM does this on their big machines.
