This is based on an earlier patch from Eric Biederman adding forwarding between macvlans. I extended his approach to allow the administrator to choose the mode for each macvlan, and to implement a functional VEPA between macvlan. Still missing from this is support for communication between the lower device that the macvlans are based on. This would be extremely useful but as others ha...

Using the same pktgen script (i.e with clone=0) I see that a veth-->bridge-->veth configuration gives about 400K PPS forwarding performance where

Hi, libvirt (0.9.11) refuses to start KVM based virtual machines on my system when changing the network connection from "host bridge" to "direct" (macvtap/macvlan), neither in "bridge" nor in "vepa" mode: "Cannot create macvlan devices on this platform" That's astonishing because I can easily setup working macvlan devices using the

Since we now have support for software CRC32c offload, turn it on for macvlan and macvtap devices so that guests can take advantage of offload SCTP checksums to the host or host hardware.
