Are you willing to share your hardware/network configuration? We are
planning a cluster
similiar to yours.

Yes, this could be interested. If possible, could you please share
some benchmark for the
same VM running from gluster and running directly from localstorage ?

What i've read is that with native gluster connector for QEMU
performance are almost identical
to the plain qemu (this looks pretty strange to me)
