Prepare a VM image in this ultimate guide

Hi there AppWorks fans,

Welcome to a new installment of AppWorks tips.

This guide will help you create a new VM image on the previous installed Oracle Virtual Box. There are some certain settings that are required to do for a proper usable image.

This post is the second part of the series for ‘AppWorks installation in 10 great steps’

This is the list of ingredients we are going to use:

  • The already installed ‘Oracle Virtual Box’ software from the previous post

  • RHEL ISO file. Downloaded from: developers.redhat.com

    • You are required to create a Red Hat account…You also need it later on for package downloading!
    • I’m using a RHEL 8.7 image with the name rhel-8.7-x86_64-boot.iso
    • Get yourself some information about the lifecycle of RHEL
  • OpenText documentation from the support site

This is the first time all documentation is NOT available in the downloaded AppWorks software package! Why not? I don’t know; you need to download it separately from the support side…It is, what it is.

Let get right into it…

Let’s begin by starting up the ‘Oracle VM VirtualBox’ software and create a new machine by hitting <Ctrl>+<n> on your keyboard or from the menu bar selecting ‘Machine’ > ‘New…’

Make sure you are in the ‘Expert Mode’. This can be switched with button on the bottom. Now make these settings:

  • Name: AppWorks {version} RHEL
  • Machine Folder: C:\VirtualBox VMs (or another place!)
  • ISO image: That’s the one we downloaded.
  • Type: Linux
  • Version: Red Hat (64-bit)


Open the ‘Hardware’ section for more settings:

  • Memory size: 9216 (= 1024 * 9 for 9Gb)
    • Make sure your local machine has enough memory available (I’m running on a laptop with 16Gb memory)
  • Processors: Just choose the max. for the green area if this is the only VM currently running.


Finally, the ‘Harddisk’ section:

  • Hard disk: Create a virtual hard disk now
  • File location: leave as is
  • File size: 250Gb
  • Hard disk file type: VDI


Now hit that ‘Finish’ button to get the overview over the image details. Now it’s time to tweak the image setting. So, select the brand-new image and hit <Ctrl>+<s> on your keyboard or click on the menu bar ‘Machine’ > ‘Settings…’

  • General category:

    • This is fine by default.
    • It’s possible to change the clipboard options and drag & drop options on the ‘Advanced’ tab. This can be handy when you want to be more flexible to access your image directly with you copy/paste actions or moving files in/out your image.
  • System category:

    • Most of the setting are fine, but we can tweak a bit here
    • On the ‘Motherboard’ tab you will see the memory settings set like you already defined. You can remove the ‘Floppy’ from the ‘Boot Order’ by unchecking it.


  • Display category

    • Can be left as is.
  • Storage category

    • Should be fine from the initial image creation!
  • Audio category

    • Disable the audio.
  • Network category

    • It is a good practice to add 2 adapters to a VM. The first one is to make connection from your local machine to the image (host-only). The second one makes internet available on the VM (NAT).
    • ‘Adapter 1’ tab
      • Enable it and attach it to ‘Host-only’ Adapter
    • ‘Adapter 2’ tab
      • Enable it and attach it to ‘NAT’
  • Serial Ports category

    • Keep it disabled.
  • USB category

    • Can be left as is.
  • Shared Folders category

    • Can be left as is.
  • User Interface category

    • Can be left as is.

This should be the end-result of all your hard configuration work! 💪


Give it a big ‘DONE’ for this post as we created a nice VM image we can use for our AppWorks installation. The next step will be to request a try-out license for AppWorks. CU next time on the following post on the series for ‘AppWorks installation in 10 great steps’ and have a great day!
