Install the Guest Additions in the guest. See ch. 4.2 Guest Additions in the User Manual for more details. Then you can use the HostKey+F combination or from the menu: View » Full-screen Mode.

You didn't read it all. See section "4.2.2. Guest Additions for Linux", or the table of contents!

hello
thanks!!

i follow this doc so i started the VM Linux and when i try to :

In the "Devices" menu in the virtual machine's menu bar, VirtualBox has a handy menu item named "Insert Guest Additions CD image"


i have this message:

Could not mount the media/drive 'C:\Program Files\Oracle\VirtualBox/VBoxGuestAdditions.iso' (VERR_PDM_MEDIA_LOCKED).

[socratis]

Did you search for "VERR_PDM_MEDIA_LOCKED"? Actually it would be better if you specified the forums in your search as well, something like "VERR_PDM_MEDIA_LOCKED site:forums.virtualbox.org".

But that means that you have another CD in your CD Drive, or that the VBoxGuestAdditions.iso is used by another VM. Check the Media Manager, Optical Disks, and see which VM has the guest additions loaded. Release it.

what can i do?
Thanks

I don't know what you did, or didn't do. I need to see the exact procedure, the exact output of the installation process. Only then we can know what failed or not.

Do not go directly for the resolution. That's the 2nd step. The 1st step is to make sure that the GAs have been installed correctly.

hi,
that's what i did :

wget http://download.virtualbox.org/virtualb ... 5.1.22.iso
mount -o loop /my/directory/VBoxGuestAdditions_5.1.22.iso /media/cdrom/
cd /media/cdrom
./VBoxLinuxAdditions.run

all is OK
the screen is still small; what can i do?

thanks
T.

[socratis]

wget http://download.virtualbox.org/virtualb ... 5.1.22.iso
mount -o loop /my/directory/VBoxGuestAdditions_5.1.22.iso /media/cdrom/

Did you even read the link that I gave you about the guest additions setup? You do NOT have to download them separately, they're included with VirtualBox, the main program.

all is OK

If you say so... But I want to see proof:

• Start the VM from cold-boot (not from a paused or saved state) / Observe error / Shutdown the VM.
• With the VM completely shut down (not paused or saved), right-click on the VM in the VirtualBox Manager and select "Show Log".
• Save only the first "VBox.log", ZIP it and attach it to your response (see the "Upload attachment" tab below the reply form).

hi,


here is the log

[Perryg]

Is the guest a server or desktop? Meaning did you install a desktop manager during install or is this a command line (console) only guest?

[trazom]

i installed Virtualbox on Windows 10
i installed Cent0S 7 Gnome Desktop (from an iso image) on Virtualbox

Thanks

[trazom]

the reason is that i want to install Alignak Monitoring on CentsOS. It's a Linux tool written in Python
