[one-users] Relationship of cpu usages

Hello,

I have a new question about that.

On http://opennebula.org/documentation:rel3.8:kvmg, I read about cgroups:

"So, thanks to cgroups a VM with CPU=0.5 will get half of the physical CPU
cycles than a VM with CPU=1.0."

How can a second VM get half of the physical CPU cycles of a first VM if
the first VM is defined to use 100 % of the CPU cycles?
