[0022] The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] A pre-processing flow manner is proposed, a flow mirror table is issued by a controller to mirror flow to a target CVK, during the live migration process, if the current virtual machine is copying disk data and has not been migrated to the target CVK, at this time, the control plane issues a flow mirror table to copy flow to the target CVK, if the virtual machine is still on the old CVK, the copied flow has no effect on the target CVK, the flow is discarded. When the underlying virtual machine migrates, the copied flow can hit the target and continue to process business, after the subsequent network topology migrates, the flow directly reaches the target CVK, and the control plane simultaneously revokes the flow mirror table to clean up the configuration.

[0024] The steps are as follows:

[0025] 1. During the virtual machine live migration process, enter the migration mode.

[0026] 2. Notify the control plane to issue a flow mirror table to mirror the flow of this virtual machine to the target CVK.

[0027] 3. The target CVK does not match the flow and directly discards it, which is processed by the original virtual machine.

[0028] 4. After migration, external flow directly reaches the target CVK, and during the underlying business model migration process, there is continuous business flow input.

[0029] 5. Close the migration mode and clean up the flow mirror table.
