CentOS 7 VirtualBox Guest Additions Installation

CentOS 7 VirtualBox Guest Additions Installation Tutorial

In the following tutorial, I’ll demonstrate how to install Guest Additions on your VirtualBox hosted CentOS 7 Minimal machine.

Although this tutorial is intended for CentOS 7 minimal, it’s will probably also work on other CentOS releases.

Update your VirtualBox

VirtualBox 4.3.12 or later is required for support in CentOS 7.x, So if you’re using older version of VirtualBox – it’s time for you to upgrade.

Update and Reboot system

After successful installation of your new and shining CentOS box, CentOS-7-installation-VirtualBox

Important Before anything!, I’d advice you to update your CentOS & reboot:

yum update
reboot

After, also try to update your kernel and reboot:

yum update kernel
reboot

You will need to be the root user for the following routine or “su -”

Prerequisities

In order to compile the guest additions you have to install make, gcc, kernel-devel in order to Install VirtualBox Guest Additions installation script.

yum install gcc make kernel-devel

OR, I’ll recommend installing the entire “Developer tools” group which will help you to avoid a lot of trouble later:

yum groupinstall "Development tools"
yum install kernel-devel

Install VirtualBox Guest Additions

Mount your guest additions:

VirtuallBox-MountGuestAdditions

Type at command::

cd /mnt
mkdir cdrom && mount /dev/cdrom /mnt/cdrom
cd cdrom && ./VBoxLinuxAdditions.run

centos-7-guest-additions

If everything “OK” – You have Guest Additions properly installed on your Centos (Minimal) machine. now Reboot:

reboot

 

That’s it!

VMware Onyx usage and examples

Overview

“Onyx is a standalone application that serves as a proxy between the vSphere Client and the vCenter Server. It monitors the network communication between them and translates it into an executable PowerShell code. Later, this code could be modified and saved into a reusable function or script.”

How to

VMware Onyx Download

Download and extract Onyx on to your vSphere Client PC.

Run and configure

  • Run Onyx and press the Connect button
    VMware Onyx
  • Input the vCenter Server IP address or host-name and “mark Launch a client after connected”
    VMware Onyx
  • Select “VMware VI Client” and input your vCenter user name and password
  • vSphere Client will now launch using port 1545
  • Return to Onyx and click start
    VMware Onyx

Now every action you will do in the vSphere client will be translated to a PowerCLI command in Onyx.

Enjoy
