![]() ![]() Virtual Ethernet Port Aggregator ( VEPA), the default mode: data from one endpoint to another endpoint on the same lower device gets sent down the lower device to external switch. Like macvlan, any macvtap device can be in one of three modes, defining the communication between macvtap endpoints on a single lower device: Typically, this is used to make both the guest and the host show up directly on the switch that the host is connected to. The endpoint extends an existing network interface, the lower device, and has its own mac address on the same ethernet segment. A macvtap endpoint is a character device that largely follows the tun/tap ioctl interface and can be used directly by kvm/qemu and other hypervisors that support the tun/tap interface. It replaces the combination of the tun/tap and bridge drivers with a single module based on the macvlan device driver. Macvtap is a new device driver meant to simplify virtualized bridged networking.
