[libvirt] [PATCH v2 3/3] xlconfigtest: add tests for 'nestedhvm' support
Posted by Wim Ten Have 8 years, 10 months ago 
From: Wim ten Have <wim.ten.have@oracle.com>

Testing various configuration schemas targeting postive, negative
and undefined 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.

The 'undefined' case is already tested by all the other tests that don't contain 
an explicit 'nestedhvm='. IMO it can be removed.
