What does this error mean, and How to fix it.. ?

[Eritrea]

I posted a question today, viewtopic.php?f=8&t=49747 to which I have not gotten a response so I installed a fresh centos on my virtual box, installed development tools and now I have this error, when I want to install guest addons.

What does it mean? How to fix it?

If I force mount it, then it acts as if nothing happened, and I everytime I want to select a shareable folder I get the same problem as my previous post.

You do not seem to be involved at all in the 2012 topic you say you asked a question in.

Also, I can't work out what URL you were attempting to give for the picture. In any case we would prefer it if you attached pictures directly here.

If the problem is simply that nothing happens when you choose "Insert Guest Additions CD" then that is normal on some guests, since many have autorun disabled as a barrier to malware. You need to find the installer executable on the CD and run it yourself.

Sorry mpack for the confusion. But I am new to this form and I do not have the privileges to post links so that is why I separated them with spaces. If you can attach them together you can see the image and or the link to my previous thread.

I already tried to patch your URLs together, with negative results already mentioned. Please just ask your question, and attach any screenshot directly here, not as a URL to another site.

Sorry again. This is the screen I get.

Btw: I am using HP Laptop with Window 7, 32 bit.
I have Virtual Box 4.2.16 with CentOs 6.5 minimal installed, using NAT and Host Only adapters.
I just re-installed CentOs, so I could get this to work. I have done the following commands.

Code: Select all

service iptables stop
yum update 
yum installgroup "Development Tools"

Now, when I got to "Devices > Install Guest Addons"
I get the error shown in the attachment.

Sorry for the noob questions.
Thanks

"Media Locked" can mean either that you already have this media mounted in the VM (i.e. you attempted to mount the same media in two CD drives), or you have an earlier version still mounted in a snapshot.

Also note the final paragraph of my first response :-

If the problem is simply that nothing happens when you choose "Insert Guest Additions CD" then that is normal on some guests, since many have autorun disabled as a barrier to malware. You need to find the installer executable on the CD and run it yourself.

If you need to continue this discussion then please shut down the VM and then attach a single .zip containing :-

1. The file VBox.log from the folder "\VirtualBox VMs\cent\Log".
2. The file cent.vbox from the folder "\VirtualBox VMs\cent".
