Can You share some thoughts/ideas or some clues regarding migration from linux bridge to ovs ? Does this migration is posible without interrupting traffic from VMs ?
I asked a similar questions back in August - https://lists.openstack.org/pipermail/openstack-discuss/2022-August/030070.h..., maybe there are some insights there.
Thank You, this thread is quite good in this case :)
We did not replace the SDN in place, but as actively looking into setting up a new cloud. Not that we do not believe in the idea of being able to replace the SDN, but we intend to change much much more and migrating through many big changes is too inefficient compared to replacing the cloud with a new one.
It looks the best way... Anyway - there is chance to make live migration between lb and openvswitch, but need to add flows by hand and add proper tag into br-int - and this 'solution' works only for external/provider network. As Sławek pointed out - in case of vxlan connection there is no opportunity to connect neturon ovs controller with linuxbridge compute nodes. -- Pozdrowienia, Lukasz
