What does "OS" for clouds mean?

Does this mean you still delegate to something like KVM/paravirtualzation for your device models, but your FTL guest OS can run multiple secure workloads inside a VM?

Or are you designing a custom OS from the ground up to run on native hardware? What constraints are you putting on hardware support to make this a tractable that's not re-implementing all of the stuff that linux has? I assume that's why it's advertised for the "cloud", because you know a priori the deployment machines you're gonna run on? Or is hardware support known by kernel devs to be a (relatively) trivial problem in the OS space, compared to the user-facing features (like processes, scheduling, memory management, etc)?

Or is the bet that microkernel = win = can implement everything linux has and more?

I'm curious about the eventual end goal for the project is, not just what currently exists (as otherwise the answer currently seems to be sentence 1)
