title: Can not install Guest Additions in VirtualBox for CentOS 6 guest
body: <p>I've just got my guest box running CentOS working perfectly, except for one problem. I'm trying to mount a shared folder. I've followed the instructions for getting the shared folder "Mountable" by using this code:</p>
  
  <pre><code>VBoxManage sharedfolder add "TEST - 250" --name "github" --hostpath "C:\filepath\github"
  </code></pre>
  
  <p>Where "TEST - 250" is the name of the VM, "github" is the name of the folder as I'd like to call it in my VM, and "C:\filepath\github" is the directory path on the Windows host where I can find the contents I would like to share.</p>
  
  <p>All seems well, and as instructed by Oracle, I am to use this command in the VM:</p>
  
  <pre><code>sudo mount -t vboxsf shared ~/host
  </code></pre>
  
  <p>I've made a directory off of the root called "host".  The problem here is that I'm getting the following message:</p>
  
  <pre><code>mount: unknown filesystem type 'vobxsf'
  </code></pre>
  
  <p>Looking at this further, I'm told that in the /sbin/ folder, there should be a file called <strong>mount.vboxsf</strong>, where there is not.</p>
  
  <p>I then read chapter 4 here: <a href="http://www.virtualbox.org/manual/ch04.html" rel="noreferrer">http://www.virtualbox.org/manual/ch04.html</a> ... more specifically section 4.2.2.1.6 for Oracle Linux, Red Hat Enterprise Linux and CentOS. I follow ALL commands they ask for:</p>
  
  <pre><code>yum install dkms
  yum update
  yum install gcc
  yum install kernel-devel
  </code></pre>
  
  <p>And just in case...</p>
  
  <pre><code>yum install kernel-uek-devel
  </code></pre>
  
  <p>All seem to work fine.  I reboot the system to activate the updates.  Once I login to the rebooted system, I type:</p>
  
  <pre><code>ls /sbin/mount*
  </code></pre>
  
  <p><em>... and I do NOT see the <strong>mount.vboxsf</strong> file.  What am I doing wrong?</em></p>
  
  <p>Also, is there a way to just get this file, and place it there? If I had that, I could perform my drive mounting, and be done with what I need to do.  Any suggestions?</p>
