Hi Han,
I'm not sure which release my patches will merge into. How about
adding the patch to update the release news after my last version
of these patches. Waiting for more reviews and comments.
Regards,
Luyao Zhong

Hi libvirt
experts,
This is the RFC for updating NVDIMM support in libvirt.
QEMU has supported four more properties which libvirt has
not introduced
yet, including 'align', 'pmem', 'nvdimm-persistences' and
'unarmed'.
The 'align' property allows users to specify the proper
alignment. The
previous alignment can only be 4K because QEMU use pagesize
as alignment.
But some backends may require alignments different from the
pagesize.
The 'pmem' property allows users to specify whether the
backend storage of
memory-backend-file is a real persistent memory. Then QEMU
will know if
it needs to guarrantee the write persistence to the vNVDIMM
backend.
The 'nvdimm-persistence' property allows users to set
platform-supported
features about NVDIMM data persistence of a guest.
The 'unarmed' property allows users to mark vNVDIMM
read-only. Only the
device DAX on the real NVDIMM can guarantee the guest write
persistence,
so it's suggested to set 'unarmed' option to 'on' and then
vNVDIMM device
will be marked as read-only.
Libvirt introduces 'alignsize', 'pmem', 'persistence' and
'unarmed' config
elements into xml corresponding to 'align', 'pmem',
'nvdimm-persistence'
and 'unarmed' properties in QEMU, and update xml parsing,
formating and
qemu command-line generating process for NVDIMM.
Thanks,
Zhong, Luyao
