Pull out the common parts of virDomainSnapshotDef that will be reused for virDomainCheckpointDef into a new base class. Adjust all callers that use the direct fields (some of it is churn that disappears when the next patch refactors virDomainSnapshotObj; oh well...). Someday, I hope to switch this type to be a subclass of virObject, but that requires a more thorough audit of cleanup paths, and besides minimal incremental changes are easier to review. As for the choice of naming: I promised my teenage daughter Evelyn that I'd give her credit for her contribution to this commit. I asked her "What would be a good name for a base class for DomainSnapshot and DomainCheckpoint". After explaining what a base class was (using the classic OOB Square and Circle inherit from Shape), she came up with "DomainMoment", which is way better than my initial thought of "DomainPointInTime" or "DomainPIT".

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.
Further information about the libvirt project can be found on the website:
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.
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:
