技术领域technical field
本发明涉及计算机虚拟化领域，尤指一种管理虚拟机的方法及装置。The present invention relates to the field of computer virtualization, in particular to a method and device for managing virtual machines.
背景技术Background technique
随着云计算、虚拟化等理念和技术的不断成熟，被越来越多的行业和用户接受认可，云计算生产环境部署规模的不断增长。在云平台中，虚拟机运行稳定性尤为重要，它直接关系着应用系统的稳定性和用户体验度。目前云平台已经存在众多技术来保证虚拟机运行的稳定性，包括主机集群、HA(High Available，高可用)、DRS(Distributed ResourceScheduler，分布式资源调度)、虚拟机迁移、FT(Fault Tolerance，容错)等等。通过这些技术可以实现虚拟机灵活、稳定、持续的工作在云平台上，提高用户应用系统稳定性。With the continuous maturity of concepts and technologies such as cloud computing and virtualization, they are accepted and recognized by more and more industries and users, and the deployment scale of cloud computing production environments continues to grow. In the cloud platform, the stability of virtual machine operation is particularly important, which is directly related to the stability of the application system and user experience. At present, there are many technologies in the cloud platform to ensure the stability of virtual machine operation, including host cluster, HA (High Available, high availability), DRS (Distributed ResourceScheduler, distributed resource scheduling), virtual machine migration, FT (Fault Tolerance, fault tolerance) )and many more. Through these technologies, the virtual machine can work flexibly, stably and continuously on the cloud platform to improve the stability of the user's application system.
但是在实际使用过程中发现，目前大部分的虚拟机高可用都是基于主机集群实现的功能，并不能针对单个虚拟机实现高可用。即便是FT技术，也需要针对源虚拟机设定影子虚拟机，当源虚拟机出现故障时，影子虚拟机直接接替源虚拟机进行工作，并且FT技术需要占用一定的物理资源才可以实现。对于虚拟机操作系统夯死(例如Windows操作系统蓝屏)的情况，云管理平台是无法感知的，也就无法实现自动监控和管理，高可用也就无从谈起。However, in the actual use process, it is found that most of the current high availability of virtual machines is based on the functions implemented by host clusters, and high availability cannot be achieved for a single virtual machine. Even with FT technology, a shadow virtual machine needs to be set for the source virtual machine. When the source virtual machine fails, the shadow virtual machine directly takes over the work of the source virtual machine, and the FT technology requires certain physical resources to be implemented. When the virtual machine operating system is dead (such as the Windows operating system blue screen), the cloud management platform cannot perceive it, so it cannot realize automatic monitoring and management, and high availability cannot be discussed.

It should be noted that, the embodiments in the present application and the features in the embodiments may be arbitrarily combined with each other if there is no conflict.
