* SR-IOV is not integrated into the OpenStack Dashboard (horizon). Users must
use the CLI or API to configure SR-IOV interfaces.
* Live migration is not supported for instances with SR-IOV ports.
* Live migration support has been added to the Libvirt Nova virt-driver in the Train
release for instances with neutron SR-IOV ports. Indirect mode SR-IOV interfaces
(vnic-type: macvtap or virtio-forwarder) can now be migrated transparently to
the guest. Direct mode SR-IOV interfaces (vnic-type: direct or direct-physical)
are detached before the migration and reattached after the migration so this is not
transparent to the guest. To avoid loss of network connectivy when live migrating
with direct mode sriov the user should create a failover bond in the guest with a
transparently live migration port type e.g. vnic-type normal or indirect mode SR-IOV.
