Actually, I use UML on one server in my firm. I want to migrate my server
on a new machine which have 2 processors. Is UML can use all processors ?
My kernel version is 2.6.12.2 with skas mode on host.
My understanding is that each UML instance will see only one processor. You
can run twice as many UMLs on a machine (at least as far as CPU time), but
each machine only gets one CPU.
