Re: [libvirt] RFC: setting mac address on network devices being assigned to a guest via PCI passthrough (<hostdev>)

(Note that even with *no new XML*, we already have a problem where just scanning all the <hostdev> entries won't tell us about all host devices that are currently assigned exclusively to guests - using a network device via macvtap in passthrough mode is effectively the same (although it's not directly exposed to the guest as the original PCI device, that device isn't available for use by any other guest, or by the host)).
