VIO9P(4)                     Device Drivers Manual                    VIO9P(4)

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 accesible
     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)
