--- features: - The nova Hyper-V driver can now plug OVS VIFs. This means that neutron-ovs-agent can be used as an L2 agent instead of neutron-hyperv-agent. In order to plug OVS VIFs, the configuration option "vswitch_name" from the "hyperv" section must be set to the vSwitch which has the OVS extension enabled. Hot-plugging is only supported on Windows / Hyper-V Server 2016 + Generation 2 VMs. Older Hyper-V versions only support attaching vNICs while the VM is turned off.
