Abstract:
A hypervisor calculates the total number of processor cycles (the number of processor cycles of one or more physical processors) in a first length of time based on the sum of the operating frequencies of the respective physical processors and the first length of time for each first length of time (for example, a scheduling initialization cycle T1, which will be explained further below). The hypervisor calculates for each virtual computer the number of possessing cycles, which is a value obtained by the total number of processor cycles being distributed in proportion to the service ratios of multiple virtual computers. In virtual processor scheduling, the hypervisor runs a virtual processor inside a virtual computer on any physical processor based on the number of hold cycles of each virtual computer.
