The objective of this post is not to claim that it is not possible to run open mpi on virtualbox. But I intend to warning of the potential challenges that are awaiting for you when you opt for running open mpi on virtualization especially virtualbox.
I have just wasted some times trying to make work. Even when it works you have a limited of processors of course depending on your hardware specification. In my case I was running a 32-bit ubuntu 14 installed on a HP laptop icore 5 . and I have at most 4 processors with only 2 usable. Everything was just a nightmare.... so many other issues came up.
If you don't have enough time and have a serious application to be developped with open mpi please you are warned don't opt for virtualbox especially if you have a normal standart hardware.
Feel free to share your experience with us.
