Embodiment Construction

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0037] see figure 1 , is a schematic composition diagram of a system for realizing remote memory exchange provided by an embodiment of the present invention. The system includes a first physical host and a second physical host.

[0038] There are three address concepts in the virtual machine system:

[0039] Machine Address refers to the physical address of the real hardware, that is, the address signal that should appear on the address bus.

Abstract

The embodiment of the invention discloses a method for achieving remote memory swap, a device and a system thereof. The method comprises the following steps: a machine page is released from a machine memory of a virtual machine, and the machine page is mapped with a physical page; the content of the physical page mapped with the machine page is transmitted to remote swap space, wherein, the remote swap space is established on a remote physical host computer. The device for achieving the remote memory swap disclosed by the embodiment of the invention comprises a page reclaim module and a remote transmission module. Partial memory of the virtual machine is swapped to the free memory of the remoter physical host computer by the method, the device and the system, and the quantity and the execution efficiency of aggregate virtual machines on a group of host computers are improved to realize higher utilization rate of the physical host computers and the lower total cost of ownership at the premise of fully ensuring the page swapping performance of the virtual machines.

Description

technical field [0001] The invention relates to computer memory sharing technology, in particular to a method, device and system for realizing remote memory exchange of a virtual machine. Background technique [0002] The virtual machine technology originated in the 1960s. Its core idea is to virtualize multiple virtual computers on a physical host, on which multiple independent operating systems can run simultaneously. These guest operating systems Guest OS pass VMM (Virtual Machine Monitor, virtual machine manager) to access actual physical resources. [0003] The goal of multi-machine aggregation virtualization is to enable a virtual machine to utilize the computing resources of multiple physical hosts, so as to improve the capabilities of the virtual machine and effectively utilize the resources of the physical host. In multi-machine aggregation virtualization, how to enable a virtual machine to use memory resources other than the host physical host to improve the perf...
