In the XML file we now have

  <cputune>
    <shares>1024</shares>
    <period>90000</period>
    <quota>0</quota>
  </cputune>

But the schedinfo parameter are being named

 cpu_shares: 1024
 cfs_period: 90000
 cfs_quota: 0

The period/quota is per-vcpu value, so these new tunables should be named
'vcpu_period' and 'vcpu_quota'.
