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.

+ <h5><a name="elementsNICSHostdev">PCI/USB Passthrough</a></h5>
+
+ <p>
+ A PCI or USB network device (specified by the <source>
+ element) is directly assigned to the guest using generic device
+ passthrough, after first optionally setting the device's MAC
+ address to the configured value, and associating the device with
+ a VEPA or 802.1Qgh capable switch using an optionally specified
+ %lt;virtualport%gt; element (see the examples of virtualport
+ given above for type='direct' network devices).
+ <span class="since">Since 0.9.11</span>
+ </p>
+
+ <p>
+ Note that this "intelligent passthrough" of network devices is
+ very similar to the functionality of a standard <hostdev>
+ device, the difference being that this method allows specifying
+ a MAC address and <virtualport> for the passed-through
+ device. If these capabilities are not required, of if you are
+ using a version of libvirt older than 0.9.11, you should use
+ standard <hostdev> to assign the device to the guest
+ instead of <interface type='hostdev'/>.
+ </p>
+
+<pre>
+ ...
+ <devices>
+ <interface type='hostdev'>

+ <address type='pci' domain='0x0000' bus='0x00' slot='0x07' function='0x0'/>
