It's as FOSS as the VirtualBox open source edition.

That would be nice, but I wouldn't hold my breath. Oracle gonna Oracle.

We don't intend to fork VirtualBox. VBox has a somewhat modular architecture where you can plug-in different hypervisor backends. That's what we did. It's not as modular, but our changes to core VirtualBox code is very small.
As far as our plans go, we are pretty open at this point. We are very interested to get to know people that find this useful!
This would be useful for anyone who needs to run bleeding edge linux kernels. Most other hypervisors have poor support when you're pinned to testing distros (For security reasons). KVM and virt-manager are uh not exactly user friendly, so being able to use the KVM backend and always be compatible with the new kernels while having the UX and UI of vbox is actually a very huge deal. This is one of the main reasons I really really hope you all manage to upstream this.
I built and tried this, it worked great, so excellent work there. I found the processor CPU core counts being grayed out unpleasant, it's not clear to me how I am supposed to adjust my core and ram values now, maybe document this?
That's odd about the core count. I only get that behavior if my host system only has 1 CPU to begin with (tested in qemu/KVM with nesting). Could you comment on your host system parameters a bit?
