Then the main question would be, do you care about using proprietary software or not?

I figured out how to use virt-manager when I was 15 years old, it’s not as hard as it seems.

VirtualBox includes non-free drivers for some features. I’d recommend using QEMU/KVM with Virt-Manager instead, since it is entirely free and open-source.
