## share folder with host

- add a filesystem device to your host:

    ```xml
    <filesystem type='mount' accessmode='squash'>
      <source dir='/home/vincent/Documents'/>
      <target dir='/mnt/workplace'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>
   </filesystem>
   ```

- on guest mount the filesystem:
- with mount cmd :`mount -t 9p -o trans=virtio,version=9p2000.L mount_tag /path/to/mount_point/on/guest`
- in your fstab:`mount_tag/path/to/mount_point/on/guest 9p trans=virtio,version=9p2000.L 0 0`
