Hi, Thanks for the reply. It was actually the bloody SElinux. Disabling it allowed the VM to be powered on. I am now still testing the write performance with both qcow2 and raw, cache none and writeback and as far as I can tell it's not good at all.

Yes the folder has full > permission to All to write.) Failing to access something, when the something has permissions, usually implies a problem with apparmor / SElinux. If this is an Ubuntu platform, then use libvirt to start the VM (i.e. define it using an XML file), and it should automatically create an apparmor policy dynamically. Otherwise, try turning off apparmor / SElinux temporarily to see whether or that's the problem. You could also try mounting your volume directly onto /var/lib/libvirt/images. > Has anyone actually was able to run it fine on Gluster 3.3 I have. Ubuntu 12.04.
