# NAME

`vio9p` — VirtIO 9p front-end driver

# SYNOPSIS

`vio9p* at virtio?`

# DESCRIPTION

In conjunction with mount_9p(8), the `vio9p` driver enables a NetBSD system running as a VM guest to mount an exported file system by the host via virtio-9p. It exports a 9p end-point of virtio-9p via a character device file for mount_9p(8).

Each exported file system is assigned a character device and accessible via /dev/vio9p0, /dev/vio9p1 and so on, respectively, in exporting order by the host.

# FILES

/dev/vio9p?

# EXAMPLES

The following command mounts the first exported file system by the host at /mnt/9p:

    # mount_9p -cu /dev/vio9p0 /mnt/9p

# SEE ALSO

virtio(4), mount_9p(8)

# HISTORY

The `vio9p` driver first appeared in NetBSD 10.0.

# AUTHORS

The `vio9p` driver was written by Ryota Ozaki <ozaki-r@iij.ad.jp>.
