Virtual screen resize

[#1]

Hi

I am using the sandbox in my Virtual box 5.1. However, I am not able to resize the virtual screen. The resize options (resolutions) are not getting enabled when I start the sandbox.

In the Devices menu, I added the VBoxGuestAdditions.iso but not able to resize even after that. Its too tedious to check and work in a small screen.

Please help.

Adding the VBoxGuestAdditions.iso file to the VM doesn't actually install the guest additions. Once you add the ISO to the image, you have to install the guest additions.

Here are the instructions for install the guest additions:

Hi Micheal

I ran the command "yim install dkms" after logging into samdbox with root/mypwd. It further installed the packages for the kernel-devl with the same being extracted and downloaded. Then I moved to /dev.

However, after that I am not able to navigate to sr0 directory. Am not sure how to proceed. If I check for cdrom under /dev, that is also available as a link file pointing to sr0.

Please help.

On a CentOS based VM, the ISO usually mounted under /media.
