I see that you are trying 'subdir' mount. (as I see '/gv0' was able to
mount fine).

If that is the case, please make sure to add a proper 'auth.allow' entry
for subdir.

something like 'gluster volume set gv0 auth.allow "/(*),/kvm01/images(*)"

But, while typing above, noticed that subdir mount is enabled by default
for every directory if none of the options are given. So, looking deeper, I
see below line in your client:

[2018-05-08 03:33:48.989219] I [MSGID: 100030] [glusterfsd.c:2454:main]
0-/usr/sbin/glusterfs: Started running /usr/sbin/glusterfs* version 3.8.8*
(args: /usr
/sbin/glusterfs --volfile-server=glusterp1.graywitch.co.nz
--volfile-id=/gv0/kvm01/images/ /var/lib/libvirt/images)

and for that version, we didn't had that particular feature.
