Title:
COMPUTER, HYPERVISOR, AND METHOD FOR ALLOCATING PHYSICAL CORES
Document Type and Number:
WIPO Patent Application WO/2015/118679
Kind Code:
A1
Abstract:
The present invention provides a computer, a hypervisor, and a method for allocating physical cores for maintaining the operation of an OS without changing the number of logical cores even when the physical cores become an obstacle, and suppressing the performance of a virtual computer from deteriorating. The hypervisor allocates a first physical core to a first logical core possessed by a first virtual machine, and allocates a plurality of physical cores to one or more logical cores possessed by a second virtual computer. When an obstacle occurs in the first physical core, the hypervisor allocates, to one or more logical cores, the physical cores other than the second physical core among the plurality of physical cores allocated to the one or more logical cores possessed by the second virtual computer. The hypervisor changes the physical core allocated to the first logical core from the first physical core in which the obstacle occurred to the second physical core.
