Can I run a virtual machine from my iPad?

I have a Windows virtual machine that I want to open it from my iPad using VirtualBox, Vmware client, or any free App that allows me to open a virtual machine file (I assume it is local to my iPad). I tried to find a solution but I could not find. There are some advanced, non-free solutions by vmware for accessing virtual machines over the cloud (VirtualHorizon). Anyone have any clue about Apps that allow me open a virtual machine file from my iPad? P.S. this is not a question for me exactly. I am trying to help someone who can not afford a PC to use Windows/Office for some homework in their iPad.
