The host machine in this example was an Ubuntu 10.04 + Fluxbox installation, built up from a minimal command line install. However this howto really ought to work on any machine running VirtualBox.
Start by installing VirtualBox, and run it (in Linux type "VirtualBox" in the terminal, taking note of the capital letters!)
Create new Virtual Machine
- Name section
Put whatever you want here; I put "MD"
- OS section
Operating Sytem - Linux
Version - Ubuntu (don't choose 64 bit)
I gave 1024 MB (There is 4 GB of RAM on the host machine, and I am able to run XP with 2 GB of RAM in another window simultaneously)
- Virtual Hard Disk
Click "Continue" on the warning, then "Finish"
With MD highlighed (or right-click on MD), click "Settings"
- Under "System" -> "Motherboard" tab -> "Boot order" section
Uncheck everything except "Network" (and put "Network" first for good measure)
- Under "Display" -> "Video" tab
Set "Video Memory" to maximum (128 MB if possible).
Note: Considering experimenting with "Enable 3D acceleration" under Extended Features, but leave unchecked for now
- Under "Network" -> "Adapter 1" tab
Change "Attached to:" to "Bridged Adapter"
Press the "OK" button.
And away you go
Start the MD! Just go with UI1 to begin with; if you find a way to get UI2 working (perhaps using the "Enable 3D acceleration" option?) then please document it here.
Update: There is some information regarding UI2 on the Virtual Core page which may be applicable to a Virtual MD.
Note: The command to start any specific virtual machine without going through the main VirtualBox menu is "VBoxManage startvm <VMName>" where <VMName> is the name of the virtual machine, so "VBoxManage startvm MD" in this example.
