Hi David, I did a quick test this morning with Proxmox and 3.7.13 and 
was able to get it working with the fuse mount *and* libgfapi.


One caveat - you *have* to enable qemu caching, either write-back or 
write-through. 3.7.12 & 13 seem to now disable aio support, and qemu 
requires that when caching is turned off.


There are setting for aio in gluster that I haven't played with yet.
