I have actively worked on Intel HAXM as part of emulator project [1]. I think there's a fragmentation problem in hypervisor scene: KVM is Linux-only, Hyper-V is Windows-only, HVF is macOS-only. Some toy hypervisors support a small subset of modern features, while lacking in other areas. Some support either Intel VMX or AMD SVM, but not both. To make things worse, Windows/macOS are making incredibly difficult for developers to deploy their own hypervisors. I believe Intel HAXM took a step in the right direction at aiming to be cross-platform, the community has unofficially even ported it to AMD CPUs as well, but more awareness is needed I don't think https://libvirt.org/ is a solution to the fragmentation problem. Whenever a new virtualization feature appears (and this happens quite often!), having to update N different hypervisors, and e

xpecting their interfaces to consistent enough and consumed by libvirt is wishful thinking: In practice it just does not happen. This hurts the development of cross-platform software that require cutting-edge hardware virtualization features. [1] https://github.com/AlexAltea/orbital

It's worth noting that there's another credible PS4 emulator project that's been around for a while: Orbital [1]. I don't bring this up to suggest that GPCS4 isn't important or innovative, but to look at the big picture. Orbital is emulating PS4 at a low level and trying to actually run the PS4 operating system; its first "hype" screenshot was of the recovery mode prompting to push the PS button on the not-yet-emulated controller. Following Orbital, I've felt for a while that there would basically be a two-pronged approach where Orbital enables reverse-engineering and another emulator leverages those insights to enable a higher-performance approach for actually playing games. GPCS4 looks a lot like it could become that other emulator. [1] https://github.com/AlexAltea/orbital
