A macvtap endpoint is a character device that largely follows the tuntap ioctl interface and can be used directly by kvmqemu and other. Containers in the macvlan network, while they are indeed natively accessible, do not populate the published NetworkSettings. Additionally, the source IP and MAC address can be identified by using an external web server access test. Macvtap interfaces in host, can tap on different physical interface, changing to different physical interface is done in host. Interaction between layers is through function calls defined in the netdev interface. Macvlan works as expected and I was successful in assigning specific IP to each container. This demonstration shows you the MAC address of the parent is kept in the pod network namespace. KVM Getting Bonding, Bridges, VLANs and Macvtap Playing Nice Together. Virtual networking TUNTAP, MacVLAN, and MacVTap Purpose. Macvlan makes it possible to create virtual network interfaces that "cling on" a physical network interface. This is conceptually very similar to the macvlan driver with one major exception of using L3 for mux-ing demux-ing among slaves. Oct 22, 2018 With MACVLAN, you can create multiple interfaces with different Layer 2 (that is, Ethernet MAC) addresses on top of a single one. When you create a macvlan network, it can either be in bridge mode or 802. 1q trunk bridge mode, traffic goes through an 802. One VM uses one dedicated Macvtap interface on host with same MAC address. It replaces the combination of the tuntap and bridge drivers with a single module based on the macvlan device driver.
