Mount Volumes into Proxmox VMs with Virtio-fs

Part of collection: Hyper-converged Homelab with Proxmox

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)

VM Migration is not possible yet, but it's being worked on!
