The virtualization API
libvirt is:

* A toolkit to interact with the virtualization capabilities of
recent versions of Linux (and other OSes).
* Free software available under the GNU Lesser General Public License.
* A long term stable C API
* A set of bindings for common languages
* A CIM provider for the DMTF virtualization schema
* A QMF agent for the AMQP/QPid messaging system

libvirt supports:

* The Xen hypervisor on Linux and Solaris hosts.
* The QEMU emulator
* The KVM Linux hypervisor
* The LXC Linux container system
* The OpenVZ Linux container system
* The User Mode Linux paravirtualized kernel
* Storage on IDE/SCSI/USB disks, FibreChannel, LVM, iSCSI, NFS and
filesystems

libvirt provides:

* Remote management using TLS encryption and x509 certificates
* Remote management authenticating with Kerberos and SASL
* Local access control using PolicyKit
* Zero-conf discovery using Avahi multicast-DNS
* Management of virtual machines, virtual networks and storage
* Portable client API for Linux, Solaris and Windows



Tasks:

1. Add glusterfs as a supported backend network storage filesystem
replacing current "nfs" which is only supported by libvirt.
2. Test the configuration and arrive at a new framework "xml" tags for
glusterfs.
3. Consolidate all the patches and send it to upstream.
