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 )
# virsh version
Compiled against library: libvirt 1.2.10
Using library: libvirt 1.2.10
Using API: QEMU 1.2.10
Running hypervisor: QEMU 2.0.0

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).
