[ovs-dev] [ovs-discuss] OVS 2.12/2.13 compilation on Ubuntu Bionic

[Maciej Jozefczyk]

Hello,

Thank you for your responses!

Is there any reason not to use the in-tree openvswitch kernel module

Yes. QoS for OVN wasn't really working before until the OVN team started
using OVS meter actions. Those type of actions are not working properly
with OVS kernel module shipped by Ubuntu Bionic (up to kernel 4.18.0 [1]),
so to test this functionality in Neutron upstream gates we compile the
module from OVS source.

This patch is actually on branch-2.12 and branch-2.13.

That is great news. Thank You!
