[libvirt] [PATCH v6 2/9] libxl: pass driver config to libxlMakeDomBuildInfo
Marek Marczykowski-Górecki

Wed Mar 21 16:32:26 UTC 2018
Preparation for global nestedhvm configuration - libxlMakeDomBuildInfo
needs access to libxlDriverConfig.
No functional change.
Adjusting tests require slightly more mockup functions, because of
libxlDriverConfigNew() call.
