... in fact, the virtio-blk device _could_ actually accept regular I/O
too. That would make it easier to boot from pmem. Is there anything
similar in regular hardware?
there is existing block device associated(hard bind) with the pmem range.
Also, comment by Christoph , about removing block device with DAX support.
Still I am not clear about this. Am I missing anything here?
