# Sharing a directory
# Sharing a directory between the host and the guest
## Virtio-fs in a nutschell
[Virtio-fs](https://virtio-fs.gitlab.io/), shorts for *Virtio shared FileSystem*, allows for a directory located on the host to be shared with a guest.
It is designed to be fast and optimized for local usage, when the host and the guest are located on the same physical machine. It is therefore a perfect fit for Phyllome OS.
Just as with other `virtio` devices, `virtio-fs` requires specialized drivers to be written for the host and the guest operating system.

* To make it permanent, edit `/etc/fstab` to look like the following:
```
share /mnt/ virtiofs rw,noatime,_netdev 0 0

```
* Make sure it works before rebooting the guest virtual machine, by un-mounting the share
