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.
