Virtualization host time management method and virtualization host system

Abstract

The invention discloses a virtualization host time management method and a virtualization host system. The method comprises the following steps: a first-grade server side host taking a clock server as a time calibration object, and carrying out time calibration on the first-grade server side host; sending a time calibration instruction to the next-grade server side host in sequence through server side hosts of all grades, so as to control the server side host of each grade to carry out the time calibration in sequence; sending the time calibration instruction to a client host belonging to the lowest-grade server side host through the lowest-grade server side host, so as to control the client host to carry out the time calibration. According to the virtualization host time management method and the virtualization host system, disclosed by the invention, the clock server is used as a time calibration basic point, and the time calibration is carried out on each grade of the host through a hierarchy framework management method, so that cooperative management of time of a virtualization host is realized, and synchronization and unification of the time of each virtualization host can be realized.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a virtualization host time management method and a virtualization host system. Background technique [0002] With the rapid development of computer technology and virtualization technology, the number of virtualization hosts continues to increase, and there are higher requirements for time management between virtualization hosts. In some application fields, the uniformity and accuracy of time between hosts Very demanding. [0003] For example, in an urban traffic monitoring system, each area is monitored by different hosts. If the hosts in each region cannot be synchronized in time, it will cause a huge loophole in the security of the monitoring system of the entire city; moreover, the monitoring systems between cities also need to be managed collaboratively, and time synchronization requirements must also be met. As another example, for scientific research activities such as ...
