Abstract

The invention provides a processing method and equipment during virtual machine scheduling. The method comprises the following steps: receiving a cache address message accessed by a virtual machine; according to the cache address message, determining a source group where data to be accessed by the virtual machine is positioned; confirming a cooperative group corresponding to the source group; when both the source group and the cooperative group miss, judging whether the source group and the cooperative group meet a cooperative condition; when the source group and the cooperative group meet the cooperative condition, storing a message which does not belong to a cache line of the virtual machine into the cooperative group; and storing the message corresponding to the virtual machine into the source group. The embodiment of the invention can be used for reducing an access delay.

Description

technical field [0001] The invention relates to storage technology, in particular to a processing method and device for scheduling virtual machines. Background technique [0002] Cloud computing data centers involve a large number of servers, which are usually built using multi-core processors. A prominent problem it faces is the low average utilization rate of servers. In order to improve the average utilization rate of servers, virtualization technology can be used. In a cloud computing data center, a physical server can be divided into multiple isolated virtual machines to provide services, and a virtual machine monitor or hypervisor (Hypervisor) acts as a firmware layer to complete the division and management of the underlying physical resources . [0003] The hypervisor can periodically schedule virtual machines to physical processor cores, or relocate virtual machines to other physical processor cores, so as to improve the utilization rate of physical processors and ...
