I will try it in my VirtualBox which was installed in my Ubuntu 12.04 Desktop.
We can find some good wizard documents from official site:
Here also is a good document that introduces how to set up MAAS in virutabox:
Ok, let me try to install my first MAAS server.
Open VirtualBox, and create a new VM named as mass for Ubuntu 64bit server.
Use the default memory size, I don't know what size is best, but I can change it after installation.
Create a new disk for this server
Use VDI as file type
Storage can be allocated dynamically
After clicking some next buttons, I create the server successfully.
Now, I will install MAAS server.
