Is it possible virtualize a real-time OS in ESXi?

Hello,

Is it possible virtualize a real-time OS in ESXi?

I want run real-time dependent applications (for example: industrial softwares) in a virtualized environment.

What I have to do for reach real-time requirements in ESXi? How do I configure? I'll have that develop some auxiliar program? Is there a API for this?

There are other softwares, but I prefer VMWare because it is more marketable.
