It supports the creation and management of guest virtual machines running Windows, Linux, BSD, OS/2, Solaris, Haiku, and OSx86, as well as limited virtualization of macOS guests on Apple hardware. There are also ports to FreeBSD and Genode. VirtualBox may be installed on Microsoft Windows, macOS, Linux, Solaris and OpenSolaris. VirtualBox was originally created by InnoTek Systemberatung GmbH, which was acquired by Sun Microsystems in 2008, which was in turn acquired by Oracle in 2010. Oracle VM VirtualBox (formerly Sun VirtualBox, Sun xVM VirtualBox and InnoTek VirtualBox) is a type-2 hypervisor for x86 virtualization developed by Oracle Corporation. GNU GPLv3 only with linking exception to GNU GPLv2 incompatible licenses X86-64 only (version series 5.x and earlier work on IA-32) VirtualBox was NOT able to really mount the GuestAdditions.iso image automatically via the "Device -> Insert GuestAdditions CD Image.".įinally I got it mounted! Then just go into the mounted dir ( cd cdrom) and exec the installer with sh n (remember you are root).Windows, macOS (only Intel-based Macs), Linux and Solaris

I tried all the solution on the net and couldn't make it work via GUI (like all the other answers). Every reload was always finding the old one (5.1 installed on VirtualBox 5.1). And now I get reported (by vbguest plugin ) that I need an updated version of GuestAdditions. In my case I updated my macOS, I was forced to upgrade Virtualbox to 5.2 (I installed without uninstalling first). Keep in mind that you not only have to insert the virtual cd, but actually run the installer before the vboxfs filesystem type will work.Īll the answer say to go via GUI and "Leave emtpy" the CD drive, but that wasn't working for me: still VERR_PDM_MEDIA_LOCKED error. Hitting the 'Force Unmount' button would be another way to unmount your drive, and after doing that the insert guest additions cd menu option should work the second time you use it. The linked article provides instructions for doing this.

Googling for that produces the answer in the first result: Įssentially, you need to unmount your virtual cd drive before inserting the guest additions cd image. Guest additions should include the software you need to use the vboxfs filesystem type.ĮDIT: Based on your updated question, the real cause error you are seeing is VERR_PDM_MEDIA_LOCKED.

Run the appropriate setup program from the virtual CD drive. When you choose it, it will be as if you inserted an installation CD to your virtual machine. Insert Guest Additions CD Image is the same thing as Install Guest Additions in a different version of Virtual Box.
