This seems to work fine but Podman is = in the process of moving from using QEMU to using Apple=E2=80=99s native = hypervisor frameworks. These don=E2=80=99t provide 9pfs servers and = instead provide a native VirtFS server (macOS now ships with a native = VirtFS client, as does Linux). =20 I believe the component bits for at least a functional implementation = already exist (FUSE and a VirtIO transport), though I=E2=80=99m not sure = about the parts for sharing buffer cache pages with the host. Is anyone = working on connecting these together? David
