If I mount the snapshots on the host, the guest system now shows the contents of re: `ls -alR`. I first hypothesized that this was the new Samba VFS, see: https://wiki.samba.org/index.php/The_New_VFS, as smbd was making fstat calls instead of the stat calls made on the client. A minimal example I worked up seems to show that fstat and stat calls made on the host do in fact automount snapshots.
