I've been using GNOME Boxes as a GUI for QEMU on my computer, but recently it broke. I think adding VirtualBox to the Fedora 38 repositories would really help people that are having the same problem as me. VirtualBox is also not available on Flathub. Thanks.
This bugzilla category is for submitting packages for review, not for requesting packages. That said, VirtualBox needs an out-of-tree kernel module and includes non-free components; both are blockers to its inclusion in Fedora. It is however already available via rpmfusion, see https://rpmfusion.org/Howto/VirtualBox
