The most frustrating & irritating thing that we face after installing OS in virtual box is that by default it comes in a very small screen and working in is not practically possible and especially when we try to install the software in GUI mode then most of the times, we won’t get the correct alignment. So, to resolve this issue we’ve to update the packages, install the kernel related packages and also, we’ve to install the supporting libraries for it like gcc, make, perl etc. Below are the steps to adjust the window size of VirtualBox so that we can convert it into full screen mode.
STEP 1: Below is the status of the display after fresh installation of OS.
STEP 2: Configure yum repository with the help of my below blog

NOTE: Follow the steps in above blog only till STEP 4
STEP 3: Execute yum repolist
STEP 4: If the installation is fresh then we don’t need to update
packages otherwise execute it.
STEP 5: install kernel devel and header as per current kernel
level
STEP 6: Insall supporting libraries
STEP 8: Go to /run/media mount
STEP 9: Execute VBox addition as per installed OS, in my case
it’s Linux
STEP 10: Select View --> Virtual Screen and then resize & scale as per
highlighted one in screenshot.
