Sharing Folders from VirtualBox on a Mac OS Host

Guest Author

As of VirtualBox 2.0.4, shared folders are still not supported for Solaris guests. However, you can still share data with your host operating system using SMB. In this example I'll explain how to set up the share on Mac OS and access it from OpenSolaris.

Step 1: Configure Mac OS to share files

Open the Sharing system preference and set File Sharing to On:

Click the Options button and select Share files and folders using SMB:

Note down your Mac's IP address, which you can find from the Network Utility. In my case is

Step 2: Access the share from OpenSolaris

Select Network from the Places menu, which will probably only show a Windows Network icon. Click the pencil icon in the Location Bar and enter the following string: smb://<ip address of Mac OS host>. For example:

And you should see your share. Note, unless you've changed the default permissions, you'll only have read access.

    How did you manage to get the IP address of ?

    Also, did you have to change the VBox networking option from NAT to HIF?

    Hi Jim,

    Thanks for the reply.

    Actually I went to your blog first, but was unable to duplicate the result in Vista.

    The following is a summary of what I did:

    In Vista, I first change the sharing option to reader (everyone)

    Then in the os200811.RC1 VM, I entered the location of


    but it showed 0 items.

    Same result (i.e., showing 0 items) if I only typed in smb://

    I think your NAT approach is better, if I can make it to work in Vista, for sharing the OpenSolaris VM with the host, as I don't have to change the VM networking option to the promiscuous mode.

    Sorry Jim, I had no idea you had just blogged on this same topic (and you gave me the idea for the blog). With regards to my IP address of, that's served up by my router. And I did do everything using NAT.
