Using the 'uuid' element for ppc64 NVDIMM memory added in the

it over to QEMU.
Another ppc64 restriction is the necessity of a mem->labelsize,
given than ppc64 only support label-area backed NVDIMMs.
Finally, we don't want ppc64 NVDIMMs to align up due to the
high risk of going beyond the end of file with a 256MiB
increment that the user didn't predict. Align it down
instead.

I think this should go into virDomainMemoryDefValidate() instead,
because this is not strictly a parse error (e.g. like invalid UUID or
missing element).
The rest looks good. Can you please post a v3 of just this patch? I will
handle the review and merge. Sorry for delayed review.
No problem,. I'll send a v4 with this change (v3 is already in the ML with other
changes).
Thanks,
DHB
