# NFS
|
||
|
|
|
||
|
|
In some cases the default shared folder implementations (such as VirtualBox
|
||
|
|
shared folders) have high performance penalties. If you're seeing less
|
||
|
|
than ideal performance with synced folders, [NFS](http://en.wikipedia.org/wiki/Network_File_System_%28protocol%29)
|
||
|
|
can offer a solution. Vagrant has built-in support to orchestrate the
|
||
|
|
configuration of the NFS server on the host and guest for you.

<strong>Windows users:</strong> NFS folders do not work on Windows
|

hosts. Vagrant will ignore your request for NFS synced folders on
|
||
|
|
Windows.

## Prerequisites
|
||
|
|
|
||
|
|
Before using synced folders backed by NFS, the host machine must have
|
||
|
|
`nfsd` installed, the NFS server daemon. This comes pre-installed on Mac
|
||
|
|
OS X, and is typically a simple package install on Linux.
|
||
|
|
|
||
|
|
Additionally, the guest machine must have NFS support installed. This is
|
||
|
|
also usually a simple package installation away.
|
||
|
|
|
||
|
|
## Root Privilege Requirement
|
||
|
|
|
||
|
|
To configure NFS, Vagrant must modify system files on the host. Therefore,
|
||
|
|
at some point during the `vagrant up` sequence, you may be prompted for
|
||
|
|
administrative privileges (via the typical `sudo` program). These
|
||
|
|
privileges are used to modify `/etc/exports` as well as to start and
|
||
|
|
stop the NFS server daemon.
|
||
|
|
|
||
|
|
|
||
|
|
## Enabling NFS Synced Folders
|
||
|
|
|
||
|
|
To enable NFS, just add the `:nfs => true` flag onto your synced folder:
|
||
|
|
|
||
|
|
```ruby
|
||
|
|
Vagrant.configure("2") do |config|
|
||
|
|
# ...
|
||
|
|
|
||
|
|
config.vm.synced_folder ".", "/vagrant", :nfs => true
|
||
|
|
end
|
||
|
|
```
|
||
|
|
|
||
|
|
If you add this to an existing Vagrantfile that has a running guest machine,
|
||
|
|
be sure to `vagrant reload` to see your changes.
