TL;DR: We need the ability to control the gluster logging from libvirt/QEMU
when using the gluster driver.


+++ This bug was initially created as a clone of Bug #1447694 +++

QEMU is unable to store Gluster specific debugging logs under
/var/run/gluster/... This is because QEMU runs as user "qemu" and does not have
write permissions there. This debugging (called 'statedump') can be triggered
from the Gluster CLI which sends an event to QEMU (when libgfapi is used).

When the glusterfs packages make sure that a group "gluster" has write
permissions to /var/run/gluster/, could the qemu(-kvm-rhev) package be adjusted
to have the "qemu" user in the "gluster" group? This would allow more debugging
options that help with potential issues when QEMU runs with disk-images over
libgfapi.so.
