In view of the discussion on SCSI passthrough, it seems to me that
this should be attached to an <interface> element:
<devices>
<interface type='hostdev'>
<source>
<address type='pci' bus='0x06' slot='0x02' function='0x0'/>
</source>
<mac address='00:16:3e:5d:c7:9e'/>
<address type='pci' .../>
</interface>
</devices>
BTW, another advantage of defining these in <interface> rather than
<hostdev> is that it makes it easier to decide when to auto-generate a
MAC address - if there's an <interface>, libvirt knows that if a MAC
address isn't given, it should always generate one. <hostdev> currently
has no concept of <mac address>, so we would have to come up with some
syntax hack to indicate that one should be created, e.g. if <mac
address=""/> is given (or maybe just an empty "<mac>"), then a mac
address should be autogenerated. That's inconsistent with existing
practice in other places that mac address is used, though.
