Simon,

It looks to me as if there is some feedback: so it may make some sense to incorporate 
some of it and send out a version 2. We may also want to CC some reps from other 
unikernel projects but Mirage OS. Or you could point them to this thread in a separate 
mail through respective channels or a hub like unikernel.org. Whatever you think may 
work best. It’s your call.

Sounds good. I am going try the unikernel.org hub and contact some people individually.


And then have a formal vote, a week after v2 of the proposal. Does this work?

Yes, this will work. I am updating the proposal and will send it out to this mailing list, right?

Thanks,

Simon

It is kind of both, however we aim a strong focus on real world
     problems: IoT, Mobile Edge Computing (MEC), Automotive, Virtual Network
     Functions (VNFs), and others.
     We have played with many Unikernels (ClickOS, Mirage, Rump, OSv, and
     others) and tried to apply them in the several areas. While doing this,
     we noticed that each area benefits differently from the properties that
     Unikernels give - which is great (e.g., instant boot times for MEC, high
     performance for NFV, resource efficiency for IoT). However, building and
     maintaining new Unikernels (as we did with ClickOS, MiniCache, and
     Minipython) is currently painful.
     Because of different focuses on properties and ported/implemented
     applications, most Unikernel today are bound to their own OS layers
     (e.g., ClickOS uses a different Mini-OS than Mirage). Each application
     requires a different subset of OS layers but also enables different
     optimizations of them.
In order to solve this, we came up with the Unicore proposal. But I
     agree with your suggestion at this point: It helps for the project start
     to focus on some initial areas. For now, I hope this is driven by the
     first contributors, and I have personally IoT in mind. Since the project
     goal is so ambitious, we should keep the long-term goal in mind from the
     beginning.

I agree that many projects (especially embedded, stubdomains, driver
     domains, NFV) have a vested interest in security and isolation. In my
     view, XSM/FLASK further restricts what a VM can do and sounds kind of
     orthogonal to the functionality of a VM (am I right?). The fact that
     Unikernels should only pick components that are actually required to do
     the job reduces the attack surface compared to general purpose OSes.
     Do you see further value with FLASK/XSM which requires early
     implementation and design decisions for Unicore? As far as I can tell
     something like Flask is implemented mostly in the hypervisor and
     toolstack, not in the guests themselves, is this right?
