Wim ten Have 5ade0ff905 xlconfigtest: add tests for 'nestedhvm' support
Testing various configuration schemas targeting postive and negative
nestedhvm under libvirt <cpu mode="host-passthrough"> configuration.

Mode "host-passthrough" generates nestedhvm=1 in/from xl format where

Intel virtualization (VT-x):
<feature policy='disable' name='vmx'/>

    or

AMD virtualization (AMD-V):
<feature policy='disable' name='svm'/>

disables virtualization mode under guest domains.
