摘要
A method for providing support for multi-tenancy in single root input/out virtualization (SR-IOV) enabled physical network interface controller (NIC) is provided. The NIC is associated with a host. The SR-IOV provides a physical function (PF) and a set of virtual functions (VFs) for the NIC. The method at a VF of the physical NIC, receives a mapping table of an overlay network which associates an identification of each of a set of virtual machine (VM) of a tenant on the host to an identification of a tunnel end point on the overlay network. The method receives a transmit packet from a VM connected to the VF and performs a lookup in the mapping table to identify source and destination tunnel end points associated with source and destination VMs in the packet. The method encapsulates the packet, for transmission through the tunnel end point associated with the source VM.
