the Exo sounds like the way to go but im curious if it c= ould be built to work with the existing linux world without rewriting every= thing for it. since i have no programming knowledge im just curious what yo= u guys think about it if you have given it any thought.

It is definately the ideal for hypervisors and with what little i hav= e read thus far feels like it manages hardware usage like containers but wi= thout most of the kernel overhead to do so.=C2=A0

= Im getting tickled about this exo kernel. think i will go find more on it.<= /div>
