'''NOTE: this got implemented in stoney cloud 1.2.10.4 and you should not have to perform the following steps.'''
Since we run Qemu as unprivileged user we have to permit access to GlusterFS from an unprivileged port as well as an unprivileged user.

=== Questions / Open Issues ===
* Where do we store the following configuration values?
** Possible storage pool types: file, gluster (others could follow)
** Host names or ip addresses (in case of gluster): tier1-storage-node-01
** Mount point: /var/virtualization/vm-persistent/ or /gv-tier1-vm-01/vm-persistent/
** Storage Pool Names: 0f83f084-8080-413e-b558-b678e504836e
** Where and how to we store the information, that we have slow and fast storage?
