[libvirt] [PATCH v2 0/3] Implement the HTM pSeries feature
Applies cleanly on top of b1acfaaf890a16ecb2fecdbe7f121eff314dd0e9. Changes from [v1]: * drop qom-list-properties machinery, as equivalent functionality has been merged in the meantime; * don't introduce scaffolding for uniform machine option handling as a requirement for implementing this specific feature: we can do ad-hoc processing for now, per the status quo, then clean up everything (including existing features) with a separate series later. Changes from [RFC v3]: * can be considered for merging, since the QEMU part already has; * fix compatibility issues with QEMU <2.12 spotted by Shivaprasad; * drop all features except for HTM, at least for the time being; * add documentation. Changes from [RFC v2]: * use qom-list-properties to probe availability; * test all features with a single XML file. Changes from [RFC v1]: * don't nest features inside a <pseries/> element; * implement all optional features.
