I will look into it.

I am interested in Fiasco.OC with Trustzone. I do not prefer pure
hypervisor approach i.e. Nova and haven't had a look at Muen. I will like
have something like a 'rehosted L4Linux or virtualized Linux' with rest of
the stack on something like L4Re, which I believe is the case with foc.

Yes. This is the exact behavior that I experienced all the three times I
tried. I will give it a try. Nothing serious for me at least at this time.

Got it. Will follow up. Need to get used to semantics of capability lists.
