As I have it in my head, the hypervisors wouldn't access the log directly, but there'd a facade process which handles it. This facade could easily do filtering to avoid having the whole log go to all clients. TBH, I don't fully understand the semantics of ovsdb yet, and it's interaction with OVN, so I'm not 100% that this approach would work. It's something I plan to study next week though.
