While we generally expect libvirt objects to be defined using the appropriate APIs, there are cases where it's reasonable for an external entity, usually a package manager, to drop a valid configuration file under /etc/libvirt and have libvirt take over from there: notably, this is exactly how the default network is handled. For the most part, whether the configuration is saved back to disk after being parsed by libvirt doesn't matter, because we'll end up with the same values anyway, but an obvious exception to this is data that gets randomly generated when not present, namely MAC address and UUID. Historically, both were handled by our build system, but commit a47ae7c004e9 moved handling of the former inside libvirt proper; this commit extends such behavior to the latter as well. Proper error handling for the virNetworkSaveConfig() call, which was missing until now, is introduced in the process.

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
