Recently after installing updates on Ubuntu 12.04 , the “Full Screen” functionality of my VM VirtualBox did not work anymore.
Every time I click on VirtualBox window – Devices – Install Guest Additions, gave me this error – VERR_PDM_MEDIA_LOCKED, which implies that your local drive allocated for your VM is locked out for any changes.
Then I realised that I had to unmount the drive, to make any changes.
So easy steps to achieve the “Full Screen” functionality are as follows –
1. ‘Devices‘ Drill down
2. If you are using VM Virtalbox Version 6.0.0 (Qt5.6.2) or later select Optical Drives (for older versions its called ‘CD/DVD Devices‘) uncheck VBoxGuestAdditions.iso
3. without restart, click on “Devices” again and ‘Install Guest Additions‘
4. The terminal automatically starts , give your password… Might take a few minutes.
5. Restart
“>Hi this doesnt work anymore
This worked for me too, (Mac OSX 10.6.8)
-Goto ‘VirtualBoxVM’ window for the guest OS.
-Devices
-CD/DVD Devices
click
‘Remove disk from virtual drive’
Then ‘Install Guest additions, as above’
Thanks! Helped me…
Correct…
Vey Helpful..
Thank you so much…
Perfect, just the answer I needed! Thanks for the steps for restarting guest additions.
Thanks, it has helped me 🙂
Thanks, that definitely helped!
not helping me…
Thanks a lot, helped me a lot
Update: It is called ‘Optical Drives’ instead of ‘CD/DVD Devices’ in the Devices Menu, for VM Virtalbox Version 6.0.0 r127566 (Qt5.6.2).
Otherwise, this worked for me, thank you very much or posting this!
