Try: provider "virtualbox" do |v| v.customize ["setextradata", :id, "VBox Internal2/Shared Folders Enable Symlinks Create/vagrant-root", "1"] end — Reply to this email directly or view it on Git Hub Hi, me again.

virtualbox updating-45

on Vagrant 1.0.6 with Virtual Box 4.2.6 on a Mac OSX Mountain Lion machine continues to result in failed symlink creation.

Backing out and attempting to use the direct Virtual Box command gives no errors and appears to set the permission, but attempting to create symlinks continues to fail.

Are there any additional suggestions in relation to this issue?

The trick for me was starting the cmd prompt as admin and running Virtual Box GUI as admin.

I'd also like to point out, which I'm fairly sure you know, that the ":id" should be replaced by whatever your Vagrant box's name was created as.

The easiest way to find that I know of is to simply open the Virtual Box GUI.

Hi all, I am using version 1.21 and added the following code to my Vagrantfile: provider :virtualbox do |vb| vb.customize ["setextradata", :id, "VBox Internal2/Shared Folders Enable Symlinks Create/v-root", "1"] end Unfortunately, I still get the Protocol Error, when creating symlinks. Thanks wrote: The share name has changed in 1.1 and above to vagrant-root instead of v-root.

I added this line to the Vagrant:: block of my Vagrantfile: customize ["setextradata", :id, "VBox Internal2/Shared Folders Enable Symlinks Create/v-root", "1"] I'm getting a slightly different error now, instead of "read only file system", I get a protocol error.

ln: failed to create symbolic link `': Protocol error I have the same issue as @kahlstrom On a OS X Lion 10.8.2, with Vagrant 1.0.6, Virtual Box 4.2.6 and a ubuntu server guest, this is not working: customize ["setextradata", :id, "VBox Internal2/Shared Folders Enable Symlinks Create/v-root", "1"] Symlink inside the share /vagrant are still in red and are not working VBox Manage setextradata :id VBox Internal2/Shared Folders Enable Symlinks Create/v-root VBox Manage.exe: error: Failed to create the Virtual Box object!
