This seems to work fine but Podman is in the process of moving from using QEMU to using Apple’s native hypervisor frameworks.  These don’t provide 9pfs servers and instead provide a native VirtFS server (macOS now ships with a native VirtFS client, as does Linux).

Nobody that I know of.  And while I understand the FUSE stuff well,
I'm shakier on VirtIO and the buffer cache.  Do you think that this is
something that a GSoC student could accomplish?
