In RHEL/CentOS 6, the support for XFS filesystems in libguestfs is
provided already by the appliance in the 'libguestfs' package.

Which host system was the XFS filesystem created on?  The xfs module in
the RHEL/CentOS 6 kernel is too old to support XFS v5 filesystems
created by more recent kernels -- see also
https://bugzilla.redhat.com/show_bug.cgi?id=1413499#c5
for few more details.

In case your filesystem was created on a RHEL/CentOS 6 host/VM, please
provide a full log of guestmount, running it with -v -x.
