Abstract

The invention discloses a virtual machine security policy migration system based on an SDN. The virtual machine security policy migration system is composed of a security policy management module, a controller cluster control module and a virtual machine migration monitoring module. The invention further discloses a virtual machine security policy migration method based on the SDN. By the adoption of the virtual machine security policy migration system and method based on the SDN, a great number of resources are saved in the whole migration process, and synchronous and flexible transferring of a security policy of a virtual machine is guaranteed automatically, rapidly, easily and conveniently along with the migration of the virtual machine.

Description

technical field [0001] The present invention relates to the technical field of virtualization, in particular to a system and method for migrating virtual machine security policies based on SDN. Background technique [0002] Virtual machine migration technology provides a convenient method for server virtualization. Currently popular virtualization tools such as VMware, Xen, HyperV, and KVM all provide their own migration components. Migrating servers can save users money on management, maintenance, and upgrades. The advantage of migration is to simplify system maintenance and management, improve system load balance, enhance system error tolerance and optimize system power management. [0003] However, the migration also brings some security policy implementation issues. For example, once the VM virtual machine is migrated, the network layer information corresponding to the VM virtual machine can be automatically migrated to the new location following the VM virtual machine...
