Embodiment Construction

[0043] The technical solutions in the embodiments of the present invention will be clearly described below in conjunction with 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.

[0044] In the embodiment of the present invention, cross-site virtual machine HA (High Availability, high availability) is mainly realized through the combination of management equipment, site control equipment and server clusters, and virtual machine re-creation and start up.

[0045]High availability HA refers to improving the availability of systems and applications by minimizing the downtime caused by routine maintenance operations (planned) or sudden system crashes (unplanned)...

Abstract

The embodiment of the invention discloses a method, device and system for managing virtual machines. The method comprises the steps that a first control device monitors the running state, in a first station, of the first virtual machine running on a first server, wherein the first server is connected with a storage device, and an LUN on the storage device is mounted on the first virtual machine and used as a virtual disk of the first virtual machine; when the state of the first virtual machine is monitored to be abnormal, the LUN mounted on the first virtual machine is dismounted by a first control device; the first control device sends starting requests of the virtual machines, and the starting requests are used for enabling a second control device to start a second virtual machine on a second server in a second station according to the starting requests of the virtual machines. By the adoption of the method, the virtual machine HA of across-physical cluster stations is achieved, data duplication between the two storage devices is not required, the investment in the network resources and storage resources is saved, and the across-station switching of the virtual machines is more efficiently achieved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a method, device and system for managing virtual machines. Background technique [0002] A single virtualization platform site generally manages a cluster including two or more servers, providing continuous monitoring for virtual machines and server hosts where virtual machines are located. When the virtual machine or the server where the virtual machine is located fails, it will automatically switch to another server to restart the virtual machine. However, if the server resources in the site where the virtual machine is located are insufficient (currently, the amount of servers in a single cluster is limited, for example, a cluster only supports 32 servers), you need to restart the virtual machine at another site to achieve cross-site high availability ( High Availability, HA). [0003] In the prior art, in order to realize cross-site HA of a virtual machin...
