Hi all,

I've tried to enable this, but can't get it working. Has anyone managed
to do this and have pointers? The instructions on the linked page seem
to be a mixture of truly ancient (from 2013) and modern, and it's
difficult to figure out what one actually needs to do.

I've set "option rpc-auth-allow-insecure on" in my glusterd.vol and
"server.allow-insecure" on the relevant volume, then restarted all my
Gluster daemons. I did a rolling restart as I can't currently shut
everything down and bring it all back up, but I can use 'qemu-img info
gluster:///[...]' successfully.

I've enabled LibgfApiSupported and restarted the engine. Starting VMs
now fails: it tries to start the VM on each host and fails with the same
message from libvirt:

libvirtd[2822]: failed to initialize gluster connection
(src=0x7f748801ff50 priv=0x7f74880367b0): Success

Unfortunately I can't see anything of much use in vdsm.log,
/var/log/messages, or the Gluster logs.

I'm using oVirt 4.1.5 and GlusterFS 3.10.5 on CentOS 7.3.

Thanks,
Chris
