networkAllocateActualDevice() is called for *all* interfaces, not just those with type='network'. In that case, it will jump down to its validate: label immediately, without allocating anything. After validation is done, two counters are potentially updated (one for the network, and one for any particular physical device that is chosen), and then networkRunHook() is called. This patch refactors that code a slight bit so that networkRunHook() doesn't get called if netdef is NULL (i.e. type != network) and to place the conditional increment of dev->connections inside the "if (netdef)" as well - dev can never be non-null if netdef is null (because "dev" is the pointer to a device in a network's pool of devices), so this doesn't have any functional effect, it just makes the code clearer.
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.
