This is the new interface type that sets up a PCI/USB network device to be assigned to the guest with PCI/USB passthrough after initializing some network device-specific things from the config (e.g. MAC address, virtualport profile parameters). Here is an example of the syntax:
<interface type='hostdev' managed='yes'> <source> <address type='pci' domain='0' bus='0' slot='4' function='0'/> </source> <mac address='00:11:22:33:44:55'/> <address type='pci' domain='0' bus='0' slot='7' function='0'/> </interface>
This would assign the PCI card from bus 0 slot 4 function 0 on the host, to bus 0 slot 7 function 0 on the guest, but would first set the MAC address of the card to 00:11:22:33:44:55.
Although it's not expected to be used very much, usb network hostdevs are also supported for completeness. <source> syntax is identical to that for plain <hostdev> devices, except that the <address> element should have "type='usb'" added if it's specified:
<interface type='hostdev'> <source> <address type='usb' bus='0' device='4'/> </source> <mac address='00:11:22:33:44:55'/> </interface>
If the vendor/product form of usb specification is used, type='usb' is implied:
<interface type='hostdev'> <source> <vendor id='0x0012'/> <product id='0x24dd'/> </source> <mac address='00:11:22:33:44:55'/> </interface> --- V2: address Eric's concerns from V1 - check for OOM after strdup - put in a NOP virDomainHostdevDefClear() rather than just commenting "there is nothing in the HostdevDef that needs to be freed" - eliminate inconsistent {} usage.

This looks odd to me; I mean why add this <interface> here but remove it in the very next patch? Maybe to prove/test that parsing and formatting works correctly even for this case. ACK Michal
