Abstract
Systems and methods for virtual machine networking can include detecting, by a virtual machine (VM), a primary virtual Network Interface Controller (vNIC) configured with a first media access control (MAC) address assigned to the VM by a hypervisor running on a host computer system, and detecting a standby vNIC configured with a second MAC address. They can further include binding a software Network Interface Controller (NIC) configured with a third MAC address to the primary vNIC and the standby vNIC, and selecting a vNIC from among those two vNICs for use by the software NIC for communicating network data packets. Additionally, they can include assigning the third MAC address to the selected vNIC, and communicating network data packets through the software NIC using the third MAC address.
