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.
