Dear All,
after some little test with Xen,
thanks to some user suggestions, problem to load image file in
loopback is possible with "-d disable" option
during mount at glusterfs client....
...appear thath GlusterFs is not able to support aio.
O.K., without this option is not possible store Xen images
in GlusterFs San....
Well, is possible planned aio support?
the command line argument "--disable-direct-io-mode" ("-d disable" in older versions) should enable AIO over glusterfs.
