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: https://www.redhat.com/archives/libvir-list/2012-February/msg00309.html 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.
