VirtualBox is not yet compatible with Fedora33, I cannot upgrade from fedora 32 to 33 because the Oracle repository does not offer rpmS for this version.
That’s a pain, I use it a lot on my Laptop.
This sounds the end I wonder, we got a kernel not patched with F32 during a while, then now a version not compatible.
I might switch to virt-manager, it is OK for sure but the UI is missing some cool features like to group VM, create bridge network on the fly, probably more.
I have been wanting to try boxes for a long time but I have not yet tried it.
When i upgraded to fedora 33 beta Virtulabox wasn’t there, so i used the one from rpmfusion and it works for me https://rpmfusion.org/Configuration
I never figured how VB is easy to use, a nice UI and also a feature I really need on a laptop, bridge the wireless NIC. It seems it is not possible with KVM
I moved away from VirtualBox and I don’t regret it.
I used Boxes for a while (about two months), but it was not stable enough in my use cases and it missed some options (especially regarding multiple ethernet networks). so I went back to virt-manager and I’m happy with it.
I have some issues with bridge, I did not find how to make really workable to get an IP from my network, not a blocker for now, but in some situation it might help to debug
