CPU Cap

A parent partition can specify a CPU cap (upper limit) for each child partition. The hypervisor then guarantees that the fraction of CPU time that each virtual processor within the partition consumes will not exceed this upper limit.

The CPU cap is specified as a fraction of a logical processor's capacity. A cap value of 0.5 indicates that each virtual processor will be restricted to using 50% of a logical processor. Valid cap values range from 0 to 1 (in which case the cap has no effect).

The CPU cap value cannot be less than the CPU Reserve.

The cap value is expressed as an integer ranging from 0x00000000 to 0x00010000. For example, the value 0x0000C000 indicates 0.75, or 75% of a logical processor.

By default, a partition's cap is set to 0x00010000, which indicates that there is no cap.
