The pinning we set up goes indeed into the <cputune> block:

—>
<vcpu placement='static'>32</vcpu>
  <cputune>
    <shares>32768</shares>
    <vcpupin vcpu='0' cpuset='0-7,16-23'/>
    <vcpupin vcpu='1' cpuset='0-7,16-23'/>
    …

What does “virsh vcpupin <domain>” give for your instance?

Cheers,
 Arne
