This patch series supports the forward mode='hostdev'. The functionality
of this mode is the same as interface type='hostdev' but with the added
benefit of using interface pools.
The patch series also contains a patch to support use of interface names
and PCI device addresses interchangeably in a network xml, and return
the appropriate one in actualDevice when networkAllocateActualDevice is
called.
At the top level managed attribute can be specified with identical results
as when it's specified for a hostdev.
Currently forward mode='hostdev' does not support USB devices.
Since the hostdev-hybrid patches are dependent on the hostdev patches,
I have also included the support for interface-type="hostdev-hybrid" and
forward mode="hostdev-hybrid" in this patch series.
The hostdev-hybrid mode makes migration possible along with PCI-passthrough.
I had posted a RFC on the hostdev-hybrid methodology earlier on the libvirt
mailing list.
The RFC can be found here:

Shradha Shah (15):
Prerequisite Patch. virDomainDevicePCIAddress and respective
functions moved to a new file called conf/device_conf.ch
Moved the code to create implicit interface pool from PF to a new
function
RNG updates, new xml parser/formatter code to support forward
mode=hostdev
Code to return interface name or pci_addr of the VF in actualDevice
Forward Mode Hostdev network driver Implementation
Forward Mode 'Hostdev' qemu driver implementation
RNG updates, new xml parser/formatter code to support interface
type=hostdev-hybrid
RNG updates, new xml parser/formatter code to support forward
mode=hostdev-hybrid
Hostdev-hybrid mode requires a direct linkdev and direct mode.
ActualParent is used to store the information about the NETDEV that
contains HOSTDEV in hybrid case.
Hybrid Hostdevs should be marked as ephemeral.
Hostdev-hybrid network driver Implementation
Hostdev-hybrid qemu driver implementation
Using the Ephemeral Flag to prepare for Migration Support.
Migration support for hostdev-hybrid.
