Method and device for obtaining operation system types and versions of virtual machines

Abstract

The invention discloses a method for obtaining types and versions of virtual machine operation systems. The method comprises the following steps of: obtaining a virtual machine identifier of a target guest virtual machine and determining the target guest virtual machine at a virtualization platform interface according to the virtual machine identifier; determining a virtual disk mirror image file carried by the target guest virtual machine; loading the virtual disk mirror image file to a host machine / or management domain; and analyzing operation system type and / or version information of the target guest virtual machine from the virtual disk mirror image file loaded in a memory of the host machine / management domain. According to the method, operation system type and version obtaining can be carried out on different virtual machines or different types of virtual machines, the operation does not need to start up a target computer and is independent of application programs of the target computer, the application programs can be used in different operation systems, resources of the target computer is not consumed, and the target computer does not perceive the operation.

Description

technical field [0001] The present invention relates to the field of virtual machines, and more specifically, to a method and device for obtaining the type and version of a virtual machine operating system. Background technique [0002] Regardless of whether it is a Windows operating system or a Linux operating system, their operating system type and version information are stored in specific locations on the disk through files. The disk here refers to a physical hard disk in a physical environment; it refers to a virtual disk image file in a virtualized environment. This article mainly deals with virtual disk image files. The specific location on the disk of the file storing the operating system type and version information is related to the specific operating system, and the location is different for different operating systems. For example, the Windows operating system is usually placed in a folder named config in the C drive; while the Linux operating system is usually...

Problems solved by technology

However, this method includes many disadvantages: the operation of obtaining information depends on the running state of the target computer, and only the computer in the power-on state can obtain the above-mentioned system type and version information; the operation of obtaining information depends on the application programs provided by the target computer, and must pass these Only provided application programs can obtain the above system type and version information; the application program used on the target computer to obtain system type and version information cannot be used across operating systems; the operation of obtaining system type and version information needs to consume the resources of the target computer; obtaining system The operation of type and version information needs to be performed on the target computer, and the target computer is aware of the operation

[0006] In view of the problems in the prior art that obtaining the type and version of the virtual machine operating system requires the target computer to be turned on, depends on the application program of the target computer, the application program cannot be used across the operating system, consumes the resources of the target computer, and the target computer has perception, etc., there is no effective solution at present. s solution
