ovs-vsctl compatibility matrix #258

Closed jshen28 closed 2 years ago

jshen28 commented 2 years ago

Hello community,

I am looking for a matrix describing compatibility between different versions of ovs-vswitchd daemon and ovs-vsctl tool. Our use case is to access ovs-vswitchd service on host from a container, and the host daemon is not cotainterized yet. Is this setup problematic and is there any link to the issues? Thank you very much for help.

Best, Jiatong Shen

It's not something we test. The goal is for interoperability between versions. This should ordinarily come down to:

When ovs-vsctl is older than ovs-vswitchd, it should work but it won't be able to work with tables or columns added after the ovs-vsctl version.
When ovs-vsctl is newer than ovs-vswitchd, it should work but attempts to configure anything based on tables or columns that are missing will fail.

(The real question is the database schema version, not the ovs-vswitchd version, but ordinarily one would keep ovs-vswitchd and its database in sync.)

Thank you for reply. Will ovs-ofctl be compatible with old ovs-vswitchd?

Yes
