Victoria Series Release Notes¶
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.
os-vif now uses the
nativeovsdb driver instead of
vsctldriver. This reduces the number of privileged call that os-vif need to make and generally improves plugging performance. In future release the
vsctlbackend will be removed.
vsctlovsdb 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
nativebackend both outperforms the
vsctlbackend and require no elevated privileges to configure the ovsdb. This both improves security and reduces plug and unplug time.
