Subject: [PULL 06/14] qapi: add failover negotiated event
Date: Tue, 29 Oct 2019 19:00:33 -0400	[thread overview]
Message-ID: <20191029225932.14585-7-mst@redhat.com> (raw)

From: Jens Freimann <jfreimann@redhat.com>

This event is sent to let libvirt know that VIRTIO_NET_F_STANDBY feature

associated with, is now hotplugged by the virtio-net device.
