Installing Virtual Box Guest Additions in Zentyal

I stumbled across Zentyal which seemed to be quite an interesting Linux distribution. I say that as they claim to be able to replace Microsoft’s Small Business Server (SBS) and co-exist with Active Directory and Exchange.

Have a look at their website for all the features.

I wanted to install the guest additions after installing Zentyal in Oracle’s Virtual Box to run the virtual machine in full screen mode. This was not as straight forward as I though it might be. Below is a video tutorial that I created to show how to install the guest additions in Zentyal. (Watch in HD and full screen)

Also note: the links below the video are for the sites I used to get this working.

Error Code: 0x000000C4 when trying to install Windows 8 or 8.1 in Virtual Box

I tried installing Windows 8.1 Preview in Virtual Box and received the below error: (If memory serves me correctly this was the same for Windows 8)

Win 8.1 error

Run the following command and then try installing Windows 8.1 Preview again.

“c:\Program Files\Oracle\VirtualBox\VBoxManage.exe” setextradata “VM Name” VBoxInternal/CPUM/CMPXCHG16B 1

This solved the issue for me. Found the information to the solution at this article here.

 


Getting your guests in Virtual Box to communicate with each other

I’ve built quite a few labs using Virtual Box but tend to forget how to get the guests to communicate with each other. Below is a quick video that I put together to show how to set up Virtual Box to get this working.

This is helpful with adding member servers to domain controllers and getting a complete AD site running. Another thing shown is how to setup sharing to access data from your guests that reside on the host machine.
