Embodiment Construction

[0055] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0056] like figure 1 As shown, it is a schematic diagram of the architecture of the virtual host security patch upgrade system provided by the embodiment of the present invention. In the host virtualization scenario, the tenant's virtual machine may miss the key security patch upgrade due to long-term shutdown / sleep, resulting in an unsafe state during the time window after the virtual machine is started and before the security patch is up...

Abstract

The embodiment of the invention discloses a method and device for upgrading security patches of a virtual machine. The method and device are applied to a virtual host. The virtual machine is contained in the virtual host and has an image file for providing an operating system. The method includes the achievement steps of copying the image file, and obtaining an image file backup; starting the image file backup in the safe environment, and carrying out security patch upgrading on the image file backup to obtain a target image file; after the security patches are successfully upgraded, replacing the image file with the target image file. In the process, as the patches are upgraded in the safe environment, the time window problem is solved, the virtual machine does not need to be matched with versions of operating systems in all types and all the patches of the operating systems, and therefore the workloads generated by upgrading the security patches are small. In conclusion, the embodiment provides the safe virtual machine security patch upgrading scheme capable of being widely applied.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for upgrading a security patch of a virtual machine. Background technique [0002] Host virtualization is a virtual technology for realizing host functions; in the host virtualization scenario, the host includes virtual machines (Virtual Machines, VMs) of tenants. A variety of software can be installed in the virtual machine of the tenant. The software may miss key security patch upgrades due to the long-term shutdown / sleep of the virtual machine, resulting in an unsafe state during the time window after the virtual machine is started and before the security patch is applied. Vulnerable to hacking or virus infection within the time window. There are extensive discussions and demands in the industry on this issue. [0003] One of the solutions is as follows: based on a dedicated application programming interface (Application Programming Interface, API) prov...
