If you are running a host kernel with the skas patch, then each UML should
only take up a couple of processes (regardless of the number of processes
running inside the UML instance).
Thus, if your server is pretty much only running UML instances, then each
UML will get about the same CPU access as other UML instances needing CPU.
If no other UML requires CPU, then the CPU will get it all. If 3 other UML
instances require CPU, then each CPU will get about 33% of CPU.
This is probably a better use of resources than limiting any particular UML
instance to xxx% CPU (since if the CPU is otherwise idle, then you're
'wasting' available processing power).
You can use 'nice' to affect which UML is selected/has priority.
