Previously all networks were composed of bridge devices created and managed by libvirt, and the same operations needed to be done for all of them when they were started and stopped (create and start the bridge device, configure its MAC address and IP address, add iptables rules). The new network types are (for now at least) managed outside of libvirt, and the network object is used only to contain information about the network, which is then used as each individual guest connects itself. This means that when starting/stopping one of these new networks, we really want to do nothing, aside from marking the network as active/inactive. This has been setup as toplevel Start/Shutdown functions that do the small bit of common stuff, then have a switch statement to execute network type-specific start/shutdown code, then do a bit more common code. The type-specific functions called for the new host bridge and macvtap based types are currently empty. In the future these functions may actually do something, and we will surely add more functions that are similarly patterned. Once everything has settled, we can make a table of "sub-driver" function pointers for each network type, and store a pointer to that table in the network object, then we can replace the switch statements with calls to functions in the table. The final step in this will be to add a new table (and corresponding new functions) for new network types as they are added. |

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
