virtiofsd - removed in QEMU 8.0, replacement seems Linux-only

[John Maline]

The QEMU Removed Features page indicates that virtiofsd has been removed, replaced with https://gitlab.com/virtio-fs/virtiofsd, a rust-based implementation.

Removed features — QEMU documentation qemu-project.gitlab.io

Browsing and searching the qemu source, it sure looks like the qemu implementation is gone. tools/virtiofsd is there in 7.2, gone in 8.0.

Searching a bit, it seems the rust implementation is Linux-only. I read this email thread as saying that’s true, with the addiitonal point that the writer had gotten some subset working for another use case.

[Virtio-fs] Compiling virtio-fs/qemu on Mac listman.redhat.com

I've been running on a macos host and a Linux (Red Hat-based) guest. Worked fine when I had virtiofsd implementation.

Alternatives?

- RH seems allergic to 9P filesystem for host file access, the qemu alternative I’m finding.

- Or I’m pointed to NFS which operationally I’m not wanting to do.

- Ubuntu ships a 9P client. Ideally I’d not have to switch to that distribution.

Anyone more clued in know if there’s some expectation / roadmap / hope that we’ll get a more portable virtiofsd on the horizon? Or is there another alternative I’m missing?
