Patent attributes
Examples of the present disclosure provide a VM packet controlling method and apparatus, applicable for an OpenStack network. The OpenStack network includes an OpenStack controller node, an OpenStack compute node, and a virtual network system. The OpenStack network is communicatively connected with an SDN controller, the virtual network system includes a VM and a virtual network apparatus responsible for forwarding packets of the virtual machine. The OpenStack controller node creates a port for the VM, informs the SDN controller of a port UUID and a forwarding rule applied on the port; the OpenStack controller node receives a port ID, and transmits a corresponding relationship between the port ID and the port UUID to the SDN controller, the SDN controller generates a flow table according to the forwarding rule applied on the port, and issues the flow table to the virtual network apparatus according to the corresponding relationship.
