Dear Mihai: That’s really helpful, thanks!
We’ll need to finish up our baseline bhyve work for Morello in simulation, and once that’s looking good, will hopefully be able to turn our attention to this more specifically in the autumn. It’s excellent to know that there has been work done already in this space.
