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.
Shi Lei (3):
add functions: load 8021q module, create/destroy vlan-dev
support new forward mode 'vlan' for virtual network
tests and docs for new forward mode 'vlan'

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.
First off - apologies no one has even looked at your v2 yet. If after a
week no one looks, please feel free to just ping the cover letter and
usually that helps get someone to look or direct at the right person.
August is a month where many take vacations so series do get lost in the
volume of upstream postings at times. Generally for network things like
this I defer to Laine as he understand the comings and goings in that
space much more so than I do.
Considering your other changes, could you just update this series with
all the changes to use switch's instead of if/then logic and repost one
you ensure that for each patch you can 'make check syntax-check'. I
have a feeling patch3 just merges into patch2.
Some of the text you put in here could be used to beef up the commit
messages for each patch which are too sparse... The commit message text
should describe the change or addition and not just be a single line header.
I think you would need to add a docs/news.xml article. But wait until
4.8.0 opens in order to repost. Should be soon anyway.
Tks,
John
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.

add functions: load 8021q module, create/destroy vlan-dev

Okay.

Okay. I'll rewrite them.

Okay.

Thanks for your directions. And I will wait and post v3 until v4.8.0 opens. :-)
