Libvirt can't do live snapshots if the underlying qemu cannot.  Since
you are using CentOS, I'd look into finding the qemu-kvm-rhev package
(the default qemu-kvm package is intentionally shipped with fewer
supported features, and you have run into one of those features).

Hi,
The package installed is qemu-kvm-1.5.3-60.el7_0.10.x86_64 on CentOS 7.
I have upgraded my libvirt and qemu also, still i am getting the same error
( Operation not supported: live disk snapshot not supported with this QEMU
binary  )
