Abstract

The invention discloses a virtual machine thermal migration method and system. The method comprises the following steps: bridging a source virtual machine on a source server to generate a first network card, and binding the first network card with a second network card virtualized by using a single input / output virtual SR-IOV technology; establishing the connection between the source server and atarget server through the first network card; sending the virtual machine memory data to the target server through the first network card by the source server in order to generate a target virtual machine on the target server according to the virtual machine memory data, thereby finishing the thermal migration between the source server and the target server. The method disclosed by the invention has the following advantages that the network card generated through bridging in the virtual machine thermal migration process is used for performing the data interaction, the virtual machine thermal migration can be stably realized so that a user cannot feel the interruption of the virtual machine service, and the migration range is extended to the whole network.

Description

technical field [0001] The invention relates to the technical field of virtualization of network server equipment, and specifically designs a method and system for hot migration of a virtual machine. Background technique [0002] Migration in a virtualized environment is divided into static migration and dynamic migration. Live migration of virtual machines is also called dynamic migration and real-time migration. Compared with dynamic migration, the biggest disadvantage of static migration is that during the migration process, the services in the client are obviously unavailable for a period of time. Therefore, static migration has many restrictions in networks with huge traffic and high real-time requirements. . Dynamic migration plays an important role in load balancing, removing hardware dependence, saving energy, and realizing remote migration of clients in geographical locations. [0003] In a server virtualization environment, business loads are on virtual machines...
