No. It doesn't. Basically, we need the version check because we are
waiting for Dan's patch to get in:

http://lists.nongnu.org/archive/html/qemu-devel/2017-03/msg00636.html

There will be no way for us to detect that. I mean, other than version
check. It sucks still, I agree on that. Therefore, even though some
older qemus do support nvdims, libvirt claims no support because they
are lacking the Dan's fix. It was discussed somewhere on the list, but I
don't remember where from the top of my head - perhaps in review of v1?
