~~~~~~~~~~~~~~~~~~~~~~~~~
well, looks like your server does not support v3
(or the client's mount tools fail to provide that)
I would double check that, as v3 mounts are currently
the only tested ones (for tcp and partially for udp,
which is of dubious value)
please double check that the tools and the server
are capable of doing/providing v3 mounts and that
tcp is enabled too, then let's retry with a chroot
on the host (using the guest tools) and within the
guest, to see if there is a difference
TIA,
