Re: [ovs-discuss] OVN DNS support questions

So as I understand it OVN DNS is not operating as either an iterative or recursive DNS resolver. It won't respond  with a referral to another DNS server nor will it do iterative requests to root, top level and  authoritative servers to find the response. It essentially intercepts the DNA requ

[ovs-discuss] options for OVN mailing lists, with a survey

Hi! TL;DR: please answer the simple question at the end of the email. Since Open vSwitch and OVN are now separate projects, it would be a good idea to separate their mailing lists as well. This is easier said than done for at least two reasons: * Mailing lists are troublesome to manage

Re: [ovs-discuss] RFC - OVN end to end packet tracing - ovn-global-trace

Skydive would be awesome, but that's a lot of work to integrate. I'd love to see it more widely deployed, but that hasn't happened. For starters, ovn-kubernetes should probably come with some kind of ovn-trace wrapper that has a bit more logic around it. I could imagine it looking something like

[ovs-discuss] [OVN] ovsdb replication of cluster mode DB

Hi, In ovsdb.7, it says " OVSDB can layer replication on top of any of its service models". I am trying to figure out how to setup the ovsdb replication for a raft OVSDB cluster. My initial thought is that --sync-from would take the 3 endpoints (for a 3 node cluster) and ovsdb-server directly
