Attempting to take snapshots of VM using virsh with the following command,

# virsh -c qemu:///system snapshot-create CentOS6-x86-001

Results in the following error,

error: internal error unable to execute QEMU command 'savevm': The command savevm has not been found

The VM's virtual disks are qcow2. Below is the XML file for this vm

It means your qemu or qemu-kvm doesn't support savevm monitor command.
You can confirm it like below.

# service libvirtd stop
# nc -U /var/lib/libvirt/qemu/$domain.monitor
