    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!

                Set up VirtFS (9p virtio) for sharing files between Guest and Host on Proxmox VE
              
          
    How-to


On Host(PVE), edit /etc/pve/qemu-server/VMID.conf

args: -fsdev local,security_model=mapped,id=fsdev0,path=/path/to/share -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare

This tells qemu to create a 9pvirtio device exposing the mount_tag hostshare (just a name to identify the mount point). That device is coupled to an fsdev named fsdev0, which specifies which portion of the host filesystem we are sharing, and in which mode.
