Oracle VirtualBox Cheatsheet

3ORACLE VIRTUALBOX CHEATSHEET Here are some of the things I had to look up at some point when using Oracle's VirtualBox hypervisor.

INSTALL GUEST ADDITIONS

To install the Guest Additions into your CentOS VM:

1. First we install necessary packages

   sudo dnf install epel-release
   sudo dnf install binutils kernel-devel kernel-headers libgomp make patch gcc glibc-headers glibc-devel dkms
   sudo dnf groupinstall "Development Tools"
   sudo dnf update
   systemctl reboot
   

2. After rebooting and getting to the terminal/GUI in the VM, we must inject the Guest Additions CD image into the VM.

   • Goto the "Devices" pulldown menu in VirtualBox, and select "Insert Guest Additions CD Image"
   • VirtualBox will request to download the CD image, allow it to do so
   • After download, it will ask to attach it to the VM, allow it to do so
   • You will now have a CD image attached to the system. The CD has been built to autorun the appropriate installer. So, for example, in GNOME, you can double click on the CD desktop icon.
   • You will have a terminal window open that will start the installation process.

   • After installation process, you must reboot

     systemctl reboot
     

   • Each time you install a new version of VirtualBox, or the kernel in a VM, you will need to repeat this step

3. To mount your shared drive:

   • On the fly, in the terminal

     sudo mount -t vboxsf SHARENAME MOUNTPOINT
     

   • In /etc/fstab

     SHARENAME MOUNTPOINT vboxsf defaults 0 0
     

   • Sample setup

     sudo mkdir /mnt/host-downloads
     sudo mount -t vboxsf host-downloads /mnt/host-downloads
