      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
