Abstract
A method for enforcing network bandwidth partitioning. The method includes verifying that a guest driver in a guest operating system (OS) is configured to enforce a resource usage policy, wherein the guest OS resides on a host, mapping a hardware receive ring (HRR) residing on a physical network interface card (NIC) operatively connected to the host to the guest OS, wherein after the mapping the guest OS is configured to receive packets directly from the HRR, determining, using monitoring information, that the guest OS should not receive packets directly from the HRR, and in response to the determination, creating a data path from the HRR to a host OS executing on the host, receiving packets for the guest OS from the HRR by the host OS over the data path, and forwarding the packets from the host OS to the guest OS.
