[libvirt] [PATCH 23/23] tests: Enhance vircaps2xml test
Martin Kletzander

Fri Mar 24 19:00:11 UTC 2017
Instead of generating all of the capabilities, let's test more of our
code by probing sysfs data. This test needs quite some mocking for
now, but it paves the road for more future enhancements (hugepages
probing, for example).
