A system includes a host computer executing virtual machines under the control of a hypervisor. A network interface card is coupled to the host machine. The network interface card implements a virtual switch with virtual ports. Each (one or more) virtual port is associated with a virtual machine. The network interface card may operate as a co-processor for the host computer by managing selected traffic flow policies, such as QoS and bandwidth provisioning on a per virtual machine basis. |
