Abstract: The present disclosure provides a virtual machine data flow management method. The method includes: receiving, by a host by using a specified network interface of an SR-IOV network adapter, an IP packet sent by a communication peer terminal, a target MAC address and a target IP address in the IP packet respectively being a MAC address of a specified network interface of the host and an IP address of a target virtual sub-machine; and forwarding, by the host according to the target IP address, the IP packet to a virtual connection function of the target virtual sub-machine in the same SR-IOV network adapter. Also disclosed is a virtual machine data flow management system. By means of the present disclosure, network communication performance of a virtual machine can be improved.

Abstract: A packet flow control method, an apparatus, and a computing node are disclosed. The method may include: negotiating, between a virtual machine and a host, an executor of a flow control policy based on a flow control capability of the virtual machine; if it is determined that a negotiated executor of the flow control policy is the virtual machine, performing, by the virtual machine, forward processing on a to-be-forward-processed packet based on the flow control policy; and if it is determined that the negotiated executor of the flow control policy is the Host, sending, by the virtual machine, the to-be-forward-processed packet to the Host, so that the Host performs forward processing on the received packet based on the flow control policy. The technical solutions provided by embodiments of the present invention help reduce address space, of the Host, occupied for processing an outbound packet flow of the virtual machine.
