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 can offer a solution. Vagrant has built-in support to orchestrate the configuration of the NFS server on the host and guest for you.
Windows users: 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:
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.
