It just occurred to me that virHostdevManager (which is used by the node 
device driver to keep track of PCI and USB devices) maintains not only 
the domain name of the current owner of a device, but also which 
hypervisor driver that domain is in. Most of the time a host will only 
be using one hypervisor driver, but there may be cases where someone is, 
e.g., using qemu and lxc on the same host, and they could theoretically 
each have a domain with the same name. I wonder if we should add this to 
the <owner> element. (If it's useful here, it may also be useful for 
nwfilter bindings). It can always be added later though, so no need to 
think about it too much now...
