The capped-cpu resource provides an absolute fine-grained limit on the amount of CPU resources that can be consumed by a project or a zone. When used in conjunction with processor sets, CPU caps limit CPU usage within a set. The capped-cpu resource has a single ncpus property that is a positive decimal with two digits to the right of the decimal. This property corresponds to units of CPUs. The resource does not accept a range. The resource does accept a decimal number. When specifying ncpus, a value of 1 means 100 percent of a CPU. A value of 1.25 means 125 percent, because 100 percent corresponds to one full CPU on the system.
The capped-cpu resource and the dedicated-cpu resource are incompatible.
