Zed Series Release Notes

21.0.0-4

New Features

  • The new ovn::controller::ovn_ofctrl_wait_before_clear parameter has been added to resolve an issue with dataplane downtime during upgrades that involve OVN schema changes. It will delay delting and re-adding openflow rules by the configured time in ms to give ovn-controller time to handle db connection / reconnection that can happen in this case. The default of 8000ms is based on upstream OVN testing with 200k openflow rules. Since it involved a change in behavior, the upstream OVN value defaults to unset.

21.0.0

New Features

  • The new ovn::controller::encap_tos parameter has been added. This parameter controls the ovn-encap-tos external id.

Upgrade Notes

  • CentOS 8 Stream is no longer supported by this module.
