METHOD FOR PROCESSING MESSAGE AFTER MIGRATION OF VIRTUAL MACHINE VM AND DEVICE THEREOF

摘要

Disclosed is a method for processing a message after the migration of a virtual machine VM, comprising: after the migration of a VM, applying a security policy corresponding to the VM to a network security device corresponding to the VM after the migration. Also provided are a corresponding network security device and network device. After the migration of a VM, by applying a security policy corresponding to the VM to a network security device corresponding to the VM after the migration, the technical solution of the embodiments of the present invention does not need to forward a message sent by the VM after the migration to the network security device corresponding to the VM before the migration for processing, thus improving the message forwarding efficiency of the VM.
