Newton Series Release Notes

1.1.0

New Features

• The ovs plugin has been extended to support vhost-user interfaces. vhost-user is a userspace protocol for high speed virtual networking introduced in qemu 2.1 and first supported in ovs 2.4 with dpdk 2.0

• The ovs plugin has been modified to ensure that the specified OVS bridge that the vif will be attached to has been created. If the OVS bridge does not exist, it will be created with the proper datapath_type.

Bug Fixes

• The OpenVSwitch plugin was registered with an entrypoint name of “ovs”, but its describe method mistakenly reported that its name was “ovs_hybrid”. The latter has been fixed to match the registered name.

• os-vif plugins were previously incorrectly registered in both the setup.py and setup.cfg. All plugin registration have been removed form the setup.py as they were not used and may have blocked registration of out of tree plugins.

• The ovs plugin now handles vifs of type VIFOpenVSwitch properly. Before, it would improperly create an extraneous linux bridge and veth pair attached to the target OVS bridge.
