Looking at your XML, I think you need to change your cpu stanza as follows:

You need to change:

  <cpu mode='custom' match='exact'>
    <model fallback='allow'>Haswell-noTSX</model>
  </cpu>

to:

<cpu mode='host-passthrough'/>

That way the exact model of your CPU is passed through to the guest VM. There 
may be more, but thats one thing I did notice at a glance which could be the 
cause.
