                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.
