Daniel Henrique Barboza 167b5fd6a8 qemu_domain.c: post parse pSeries NVDIMM align with PARSE_ABI_UPDATE
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 c7d7ba85a6.

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.

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