Hi, everyone! This patch supports VLan by '8021q' kernel module other than by OVS. The way of '8021q' is simpler and more robust. Mode 'vlan' is like mode 'route' except these major differences: - mode 'vlan' inserts a vlan-device between the specified host's interface and the internal bridge. The vlan-device is based on '8021q' kernel module. - mode 'vlan' has no routed iptables rules but has other common iptables rules It can simplify the work of management apps whose developers want to implement VLan but don't want to introduce OVS into their project. Thank John for his comments in v1. v1 here: https://www.redhat.com/archives/libvir-list/2018-July/msg00331.html since v1: - Change docs/formatnetwork.html.in - Change docs/schemas/network.rng - Add tests/networkxml2* - Other code fixes Besides, I have post two patches followed by John's suggestions. - Replace 'if' type conditions with 'switch' for VIR_NETWORK_FORWARD_* https://www.redhat.com/archives/libvir-list/2018-July/msg01537.html This has been accepted. - Introduce timeout mode for virKModLoad to solve the potential problem of the 'strange delay' when loading '8021q' module https://www.redhat.com/archives/libvir-list/2018-August/msg00605.html This has been rejected and I don't know wether I should continue to solve this problem. Now I just check the INIT process code of '8021q' module and I think this module should not cause delay now. The loading time of '8021q' by virKModLoad on my PC is about 30 milliseconds.
