Converting from virObject to GObject is reasonably straightforward, as illustrated by this patch for virIdentity In the header file - Remove typedef struct _virIdentity virIdentity - Add #define VIR_TYPE_IDENTITY virIdentity_get_type () G_DECLARE_FINAL_TYPE (virIdentity, vir_identity, VIR, IDENTITY, GObject); Which provides the typedef we just removed, and class declaration boilerplate and various other constants/macros. In the source file - Change 'virObject parent' to 'GObject parent' in the struct - Remove the virClass variable and its initializing call - Add G_DEFINE_TYPE(virIdentity, vir_identity, G_TYPE_OBJECT) which declares the instance & class constructor functions - Add an impl of the instance & class constructors wiring up the finalize method to point to our dispose impl In all files - Replace VIR_AUTOUNREF(virIdentityPtr) with g_autoptr(virIdentity) - Replace virObjectRef/Unref with g_object_ref/unref. Note the latter functions do *NOT* accept a NULL object where as libvirt's do. If you replace g_object_unref with g_clear_object it is NULL safe, but also clears the pointer.

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 2.0 (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.
Contributing
The libvirt project welcomes contributions in many ways. For most components the best way to contribute is to send patches to the primary development mailing list. Further guidance on this can be found on the website:
