What this patch allows you to do is to create a table of IP address to host (defined by its hardware / MAC address) for each virtual network. Optionally you can also assign a hostname. When a host starts up and requests an IP address through DHCP, if it is in this table then it gets the fixed IP address from the table and, optionally, a fixed hostname.
Four new API calls are added. Two are required to list the contents of the mapping table. Two more allow you to add and delete a mapping.
The mapping table is semi-permanent. It is stored in /var/lib/libvirt/hosts-<networkname>.conf and survives across libvirtd restarts.
Cool stuff, but why isn't this just an addition to the network's XML definition?
Well indeed. It's essentially because this implementation was thought to be easier. I haven't tried the other implementation so I'm not categorically sure that is true.
