vsock on macOS: QEMU/HVF vs Virtualization.framework vs libkrun

Research notes, August 2026. Question: can a guest VM on a macOS host reach the host over AF_VSOCK, and specifically can the guest initiate that connection?

QEMU on macOS: no — and it's four independent blockers, not one

1. Homebrew ships vhost-user compiled out. Not a Homebrew choice — meson.build:223 has .disable_auto_if(host_os != 'linux'), so the auto feature silently resolves to disabled on Darwin. The formula never passes --enable-vhost-user, so it follows mechanically.
2. The enabling patches never merged. Garzarella's series mostly landed in QEMU 9.1 — including memory-backend-shm — but the three that flip the default (vhost-user: enable frontends on any POSIX system, libvhost-user, contrib/vhost-user-blk) are still only on his GitLab branch, verified absent from master and every release through 11.1.0. Stuck ~2 years on one flaky vhost-user/reconnect qtest that fails on FreeBSD and *frequently on mac
