Abstract

The embodiment of the invention discloses a cloud host creation method and device and a cloud service system. The method is applied to a target computing node in the cloud service system and comprisesthe steps that a creation instruction for a target cloud host is received; whether or not a target mirror file needed for creating the target cloud host is saved locally; if not, a target cache nodeis determined from cache nodes; a first request for acquiring the target mirror file is sent to the target cache node; target information fed back by the target cache node according to the first request is received; whether or not the target information is the target mirror file is judged; if yes, the target cloud host is created according to the target mirror file; if not, a second request for acquiring the target mirror file is sent to a mirror node; the target mirror file fed back by the mirror node according to the second request is received; and the target cloud host is created accordingto the target mirror file. According to the cloud host creation method and device and the cloud service system, the pulling time of the mirror file and the creating time of the cloud host can be shortened.

Description

technical field [0001] The present invention relates to the technical field of virtualization, in particular to a cloud host creation method, device and cloud service system. Background technique [0002] In cloud computing technology, a cloud host is a plurality of parts similar to independent hosts simulated on a physical machine through virtualization technology, and they share the hardware resources of a physical machine. The physical machine can also be called a host. With the popularization and commercialization of virtualization technology, more and more users need to create cloud hosts on host machines to improve the utilization rate of host machines. [0003] For example, in the OpenStack (cloud computing management platform) architecture, when creating a cloud host on a host machine, you first need to obtain the system disk image file of the cloud host. After obtaining the above system disk image file, the host machine can Create a cloud host based on the image fi...
