[libvirt] [RFC v2 0/3] update NVDIMM support

Hi libvirt experts, This is the RFC v2 for updating NVDIMM support in libvirt. There are some gaps between qemu and libvirt, libvirt has not supported several config options about NVDIMM memory while qemu is ready now, including 'align', 'pmem', 'unarmed' and 'persistence'. I have already reworded and recoded my patches according to some feedback comments from community. Besides I keep all testcases divided, since every option is independent. Before you experts review, please let me clarify one point: 'persistence' option I investigated this option, it is used to add platform-supported features about NVDIMM data persistence to guest. I did not change this part in this RFC v2, because I'm not sure where I should put it in domain config xml file. What about in <features> elements? Or kick it out of this patch set, because it seems like another type option which is different from other three options here. I'd like you give some suggestions. Thank you in advance.
