I am trying to set up file sharing on Virtual Box on my mac. When I chose "Insert Guest Addition CD Image", I get the following errors:
Unable to insert the virtual optical disk
/Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso
into the machine <machine name>
Would you like to try to force insertion of this disk?
Could not mount the media/drive
'/Applications/VirtualBox.app/Contents/MacOS/VboxGuestAdditions.iso'
(VERR_PDM_MEDIA_LOCKED)."
What to do?

Re: Cannot insert Guest Addition CD Image
Remove whatever ISO is already mounted in the VM settings. Might help to also release the disk usage in the guest.

Re: Cannot insert Guest Addition CD Image
I actually have the same issue as tjaldur, and I just tried what you suggested. If I remove the mounted "VBoxGuestAddition.iso", I will not able to insert any guest addition CD image after I start the engine.
I actually did successfully installed the guest addition before, but the "auto-resize guest display" greyed out today, so I'm trying to reinstall the guest addition. Should I uninstall the old one first? How do I uninstall it?

Re: Cannot insert Guest Addition CD Image
I am trying to install the guest additions for my openSUSE 13.2 guest, as described in 4.2.1.1 Installation section of the User Manual, which says:
"In the "Devices" menu in the virtual machine's menu bar, VirtualBox has a handy menu item named "Insert Guest Additions CD image", which mounts the Guest Additions ISO file inside your virtual machine.”
When I click “Insert Guest Additions CD image”, I get the following error:
Could not mount the media/drive '/Applications/VirtualBox.app/Contents/MacOS/VBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED).
The first suggestion in this thread says to remove whatever ISO is already mounted in the VM settings. I assume I do this by going to the Storage tab in Settings, where I see the openSUSE-13.2-DVD-x86_64.iso under Controller: IDE. However, it won’t let me remove it.
The second suggestion in this thread says to “eject” whatever is using the virtual drive first. I assume I do this by selecting Devices > Optical Drives > Remove disk from virtual drive. This just results in a similar error: Could not unmount the currently mounted media/drive (VERR_PDM_MEDIA_LOCKED).
I am using Fixed not dynamic. I can see the VBoxGuestAdditions.iso disk image in my Mac Finder window. But I have no idea at this point how to insert it. If I try to choose that disk image from the Devices menu, it doesn’t seem to be accessible (can’t right-click on VirtualBox under the Applications folder go drill down to the iso as the VirtualBox icon is grayed out.)

Re: Cannot insert Guest Addition CD Image
Eject the cd/dvd from within the guest first or shut down the guest and remove it using the settings -> storage section
Re: Cannot insert Guest Addition CD Image
Ah, ok. It worked. Thanks!
