In order to hopefully address [libvirt#147] at long last, I've picked up Roman's patches from 2018 and attempted to forward-port them. More specifically, I've used the [roolebo/hvf-domain] branch as a starting point, since it seems to contain a few improvements over [v2] and was just easier to pick up. The code is mostly his own, so I've retained the existing authorship information, but I've dropped Reviewed-by tags for commits that have been modified in non-trivial ways. I've applied very minimal style tweaks along the way, but overall I've tried to modify the existing patches as little as possible. I've added a few changes of my own, which I've marked as "fixup!" when I felt that they should be squashed into the previous patch rather than existing as separate commits. The new test cases, such as they are, pass, and no regressions to KVM support appear to have been introduced in the process. I don't currently have access to a machine running macOS, so I can't verify that it's actually possible to start a hardware-accelerated VM by myself, but a user has confirmed on the GitLab issue that the new feature works. Changes from [v5]: * rebased on top of master, dealing with a couple of straightforward merge conflicts in the process; * moved NEWS entry to the 8.1.0 section. Changes from [v4]: * fixed an issue that prevented machine types from being probed correctly, effectively making the entire thing non functional; * only report HVF support as available when the guest architecture and the host architecture match. Changes from [v3]: * reintroduced the patch that was missing in the initial version of the forward-port; * converted the documentation to reStructuredText and trimmed it significantly; * reworked virQEMUCapsAccelStr() based on Dan's suggestions; * reworked macOS support in the test suite based on Dan's suggestions; * fixed a few minor issues found while doing the above. Changes from [v2]: * rebased on top of master; * added a couple of simple test cases.
