More Information
Summary:The invention discloses a virtual machine hot upgrade method and device, and the method not only optimizes the service interruption time caused by the interruption of a network virtual device in the hot upgrade process through introducing a network virtual protocol re-negotiation mechanism, but also realizes the rollback of the network virtual device after the hot upgrade fails based on the re-negotiation mechanism, thereby improving the user experience. The network virtual device after hot upgrading can be rolled back to the state before upgrading, and the risk that hot upgrading affects customer services is greatly reduced. 本申请公开了一种虚拟机热升级的方法及装置，其方法通过引入网络虚拟协议重协商机制，不仅优化了热升级过程中因网络虚拟设备中断而造成的业务中断时间，而且基于重协商机制实现了热升级失败后网络虚拟设备的回滚，可以将热升级后的网络虚拟设备回滚到升级前的状态，大大降低热升级影响客户业务的风险。
