Hi,

We have a SR-IOV guest whose xml looks like shown below:

------
 <interface type='hostdev' managed='yes'>
      <mac address='fa:16:3e:3d:72:18'/>
      <driver name='vfio'/>
      <source>
        <address type='pci' domain='0x0000' bus='0x01' slot='0x12'
function='0x7'/>
      </source>
      <vlan>
        <tag id='2'/>
      </vlan>
      <alias name='hostdev0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x05'
function='0x0'/>
    </interface>
