Commit 57f5621f modified nwfilterInstantiateFilter to detect when a filter binding was already present before attempting to add the new binding and instantiate it. Additionally, the change to nwfilterStateInitialize to call virNWFilterBindingObjListLoadAllConfigs (from commit c21679fa3f) to load active domain filter bindings, but not instantiate them eventually leads to a problem for the QEMU driver reconnection logic after a daemon restart where the filter bindings would no longer be instantiated. Subsequent commit f14c37ce4c replaced the nwfilterInstantiateFilter with virDomainConfNWFilterInstantiate which uses @ignoreExists to detect presence of the filter and still did not restore the filter instantiation call when making the new nwfilter bindings logic active. Thus in order to instantiate any active domain filter, we will call virNWFilterBuildAll with 'false' to indicate the need to go through all the active bindings calling virNWFilterInstantiateFilter to instantiate the filter bindings.

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.

License
The libvirt C API is distributed under the terms of GNU Lesser General
Public License, version 2.1 (or later). Some parts of the code that are
not part of the C library may have the more restrictive GNU General
Public License, version 2.1 (or later). See the files COPYING.LESSER
and COPYING for full license terms & conditions.
Installation
Libvirt uses the GNU Autotools build system, so in general can be built and installed with the usual commands. For example, to build in a manner that is suitable for installing as root, use:
$ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
$ make
$ sudo make install
While to build & install as an unprivileged user
$ ./configure --prefix=$HOME/usr
$ make
$ make install
The libvirt code relies on a large number of 3rd party libraries. These will
be detected during execution of the configure script and a summary printed
which lists any missing (optional) dependencies.
