Creating a NexGEN virtual Windows machine on a Mac (**using a shared virtual Hard drive **) with VirtualBox

These instructions show how to setup VirtualBox for PXE/Netboot, share a vdi hard drive among users/ accounts on a mac and how to move the VirtualBox settings or preferences between users. I assume you have access to Unified Registration and have already setup Windows computers with NexGEN.  The campus Windows licence allows us to install Windows enterprise on macs without a Windows licence (or on PCs that have a Windows licence, any version).

Click on thumbnails to view the images (in a new tab/window).

**Suggestions required for sharing the Virtual Drive among the mac users are bounded by asterisks.**  They will work for sharing a Linux installation as well. Send corrections and suggestions to Dave Carmean (  

1) Download both 'VirtualBox #.#.# for OS X hosts' and  'VirtualBox #.#.# Oracle VM VirtualBox Extension Pack' from

1b.) **New! Before you start Virtualbox, download this zipped folder which contains the 'VirtualBox VMs' folder to be placed into the "/Users/Shared" folder and the 'VirtualBox' preferences folder to be placed into your users library folder (In the finder open the hidden library folder by holding down the option key and choosing 'Go/Library' from the menu). Then skip steps 4-8. Make sure the user has the correct access permissions set (step 12 & 13) and you change the mac address (step 9)!**

2) Install Virtualbox and start it.

3)  Install extension pack (just double click on it)

4)** Go into VirtualBox Preferences/General and change the default location from your user folder to "/Users/Shared/VirtualBox VMs" **

5) Create and name a new Virtual Machine.
Name and Windows Choice

6) Allocate a reasonable amount of RAM- (e.g 2 to 4GB (4096MB) if you have 8GB- this setting can be changed later [Minimum requirement is 1 GB (32-bit) or 2 GB (64-bit)]
Memory Size

7) Create a (dynamically allocated) hard drive more than 30GB- I suggest 40 or more, this cannot be (easily) changed. **  To share the same VM with other mac users on the computer Click on the small folder icon to make sure it is in the users shared space, e.g. /Users/Shared/VirtualBox VMs/Windows7_harddrive_name.vdi (But you took care of this in step 4)  **

1- Virtual Hard Drive Creation Virtual Hard Drive Creation File Location- /Users/Shared/

8) Click on Settings and System tab- Motherboard
Choose Network so it and 'Hard Disk' are checked. (Uncheck floppy/CD.)  (Do not change the order! network is last).

Drive Set Up

9) Change to Network tab, and changed 'Attached to' from 'NAT' to 'Bridged'.  Click triangle to see Advanced and copy the MAC Address (e.g. 060047109E30). ** You might want to save the mac address in the /Users/Shared/ Folder for easy access.**
Bridged Network Adapter

10) Register mac address with unified registration as usual for NexGEN. You may want to (need to?) go into the Mac System Preferences/Energy Saver and temporarily turn off computer sleep.

11) Start machine... hit escape to the screen that asks for a Virtual optical boot disk, it should then net boot to the correct network location to download and install NexGEN Windows (as you have done with a regular NexGEN setup). Since this can hours, you probably should turn off sleep on your host machine.

Hit escape to boot from network

12) ** Quit VirtualBox, Copy 'your' user VirtualBox preferences folder (/Users/YourUserName/Library/VirtualBox or ~/Library/VirtualBox) to the /Users/Shared/ folder. Go to /Users/Shared/ folder and give read/write access to the "VirtualBox VMs" folder (command-i, add users that will need access to it (Use 'Get Info', scroll to bottom, Under 'Sharing & Permissions' add users/groups and give them read/write access).  **

13) **Login as the other users, and copy 'your' user VirtualBox preferences folder to their Library folder. Make them 'owner' of that folder with read/write privileges. Alternatively, each user must set it up following the above instructions but use the existing HD (and enter the mac address for the Bridged adapter, not use the auto-generated mac address). **
