Subject: [PATCH v5 03/11] pci: mark devices partially unplugged
Date: Wed, 23 Oct 2019 10:27:03 +0200 [thread overview]
Message-ID: <20191023082711.16694-4-jfreimann@redhat.com> (raw)
In-Reply-To: <20191023082711.16694-1-jfreimann@redhat.com>
Only the guest unplug request was triggered. This is needed for
the failover feature. In case of a failed migration we need to
plug the device back to the guest.
