A previous patch removed the pSeries NVDIMM align that wasn't being done properly. This patch reintroduces it in the right fashion, making it reliant on VIR_DOMAIN_DEF_PARSE_ABI_UPDATE. This makes it complying with the intended design defined by commit c7d7ba85a624. Since the PARSE_ABI_UPDATE is more restrictive than checking for !migrate && !snapshot, like is being currently done with qemuDomainAlignMemorySizes(), this means that we'll align the pSeries NVDIMMs in two places - in post parse time for new guests, and in qemuDomainAlignMemorySizes() for all guests that aren't migrating or in a snapshot. Another difference is that the logic is now in the QEMU driver instead of domain_conf.c. This was necessary because all considerations made about the PARSE_ABI_UPDATE flag were done under QEMU. Given that no other driver supports ppc64 there is no impact in this change. A new test was added to exercise what we're doing. It consists of a a copy of the existing 'memory-hotplug-nvdimm-ppc64' xml2xml test, called with the PARSE_ABI_UPDATE flag. As intended, we're not changing QEMU command line or any XML without the flag, while the pseries NVDIMM memory is being aligned when the flag is used.

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.
