Victoria Series Release Notes

2.2.0-4

Bug Fixes

  • Linux kernel 5.8 changed the sysfs interface that is used to discover the interfaces used for OVS offloads for certain NIC models. This results in network plugging failure, as described in bug #1892132. This release fixes the plugging issue by properly handling the new sysfs structure.

2.2.0

Upgrade Notes

  • os-vif now uses the native ovsdb driver instead of vsctl driver. This reduces the number of privileged call that os-vif need to make and generally improves plugging performance. In future release the vsctl backend will be removed.

Deprecation Notes

  • The vsctl ovsdb driver is now deprecated for removal. The default ovsdb interface has now been updated to native. This will use the ovs python binding instead of invoking the ovs-vsctl CLI. The native backend both outperforms the vsctl backend and require no elevated privileges to configure the ovsdb. This both improves security and reduces plug and unplug time.
