Part of collection: Hyper-converged Homelab with Proxmox
15-04-2025: Seems Proxmox added this now to the GUI; see Using VirtioFS backed by CephFS for bind mounts how to use it.
Virtio-fs is a shared file system that lets virtual machines access a directory tree on the host. Unlike existing approaches, it is designed to offer local file system semantics and performance. The new virtiofsd-rs Rust daemon Proxmox 8 uses, is receiving the most attention for new feature development.
Performance is very good (while testing, almost the same as on the Proxmox host)
