| vcpus                      | 8                      |

The result is 
  <vcpu placement='static'>8</vcpu>
  <cputune>
    <vcpupin vcpu='3' cpuset='0-7,16-23'/>
    <vcpupin vcpu='7' cpuset='8-15,24-31'/>

  <cpu>

      <cell cpus='0-3' memory='1024'/>
      <cell cpus='4-7' memory='1024'/>
    </numa>
  </cpu>

The cputune should be:

  <cputune>
    <vcpupin vcpu='0' cpuset='0-7,16-23'/>
    <vcpupin vcpu='1' cpuset='0-7,16-23'/>
