A method for managing a guest OS executing on a host. The method includes receiving, from the guest OS associated with a first MAC address, a second MAC address, wherein the first MAC address is associated with a first guest VNIC, wherein the second MAC address is associated with a second guest VNIC; configuring an intermediate VNIC executing on the host OS to forward packets associated with the second MAC address to the guest OS, wherein packets associated with the first MAC address and received by the intermediate VNIC are forwarded to the guest OS; and forwarding the second MAC address from the intermediate VNIC to a device driver associated with a physical NIC, wherein the device driver configures a classifier on the physical NIC to forward packets associated with the second MAC address to a first HRR located on the physical NIC associated with the intermediate VNIC.
