What does this give me that I don't already get from KVM and virt-manager on Linux? Not getting it.

The out-of-the-box performance of Windows in VirtualBox is very good and usually better than virt-manager (Qemu). You can tune Qemu to great performance as well, but it takes some fiddling. VirtualBox is in general very user friendly.

Guest integration (drag'n'drop, clipboard), USB passhthrough and audio support is also top-notch in VBox.

That appears to be the VirtualBox OSE license, copied from the original Oracle package, not the license for this specific release. It’s unclear how this new derivative or work is licensed.

The intention is to have this under the same license as the VBox open source release. If there is a way to clarify this more on the Github page, please advise. :)

Finally! Every time I need to run a virtual machine, I choose libvirt because it's more performant and easy to deal with than Virtualbox (no kernel module, etc.), but the GUI choices are pretty terrible. The "best" libvirt GUI is virt-manager and it's very, very buggy and lacking features (i.e. doesn't play nice with HiDPI screens, no way of configuring IPv6, etc.) Many times I have caved and chosen VirtualBox simply…

Great! What guests do you typically run where you see better performance with libvirt/kvm?

Is there a connection to User Mode Linux (UML) from around the same time? Or are these completely unrelated projects? I get that running a kernel in the user space provided by another kernel is not really the same as a proper hypervisor, but have never really dug deep into why and what the various tradeoffs are.

There is no real connection to UML here. Hardware virtualization (Intel VT, AMD-V) are much faster in practice and also don't require the guest operating system to be heavily modified. So besides as curiosity or test vehicle, approaches like UML are pretty dead.
