As some of you may have noticed, since QEMU 2.9.0, an accelerator known as “hax” has been available for Windows and macOS builds of QEMU, thanks to the hard work of Vincent Palatin and help from this community (Paolo Bonzini, Stefan Weil, et al.).

The accelerator requires a host kernel module (driver) known as Intel Hardware Accelerated Execution Manager (HAXM), i.e. intelhaxm.sys on Windows or intelhaxm.kext on macOS, similar to how the KVM accelerator depends on kvm.ko on Linux.

Today, we released the source code of the HAXM kernel module under the BSD 3-clause license:


We look forward to working with the community to improve HAXM (both the kernel module and the accelerator). The code is accompanied by some basic documentation (README.md and API.md), which is incomplete, but hopefully helps people get started. If you have any questions or suggestions, please create an issue or post a comment on GitHub.
