Using Virtualbox create a Centos vm using the iso dvd image referenced in the earlier post.

Reboot when complete

Log in

Insert the VirtualBox Guest Editions software

Select “Devices -> Insert Guest Editions CD Image …” from the VirtualBox window.

Then select “Run”

When complete hit “Return” and shutdown the system.

Add a shard drive

In this example I will add the windows Downloads folder so that it can be shared with the Centos linux VM.

In VirtualBox with the Centos VM selected, choose “Settings” from the top menu (or right click the host and choose settings)

Select “Shared Folders”

Using the RHS “+”option, add the Downloads folder

Select “OK” and then  start the host and login.

Open a terminal and execute the command:

sudo usermod devopsdba -a -G wheel,vboxsf

When complete logout and log back in.

Execute the command:

ls /media/sf_Downloads/

The Downloads folder is now accessible to the VM.

Update Centos

Enter the command

sudo yum update -y

This will bring the system up to the latest update
