 I think the element name should be generic and
 the percentage (0..100 or 0..vcpu*100) is better as 
 the element value. That's intuitive to me.
 
 How about the follwing?

  <cputune>
    <capping>50</capping>
  <cputune>

 If it is not possible to control enough only one
 "capping" parameter, how about passing the other parameter
  as qemu driver's parameter via /etc/libvirt/qemu.conf ?
