If you do plan to use glusterfs as a vm backing store and use glusterfs replication then look into glusterfs 3.3 beta 3, you will see why as you read the documentation. I am using glusterfs 3.2.6 but without replication to store VMs.<div>

GlusterFS clients work just fine inside virtual machines. Make sure you use vhost_net to get maximum performance to the VM. I was able to push nearly 8 Gbps to the VMs using the kernel level virtio-net driver. <div><br></div>
