I recently changed Centos 8 for Fedora due some issues my Server has with Storage drivers (my old Dell Raid drivers are not longer supported in Centos 8, so any update was a bit of a nightmare...)
Since I wanted to try to use Vagrant with VirtualBox, I tried to install it without checking much, until I realised there is not VirtualBox support for Fedora 33 yet.
I found couple of guides to get it done though:
VirtualBox 6.1 on Fedora 33/32, CentOS/RHEL 8.2/7.8
Install VirtualBox 6.1 on Fedora 33
Both of them are very similar, and in both of them, you need to modify the RPM in order to change the default Python VirtualBox try to use.
However, that is not the only issue you could face, so I decided to post this in order for me to remember for next time, but I'm sure next time I try to install VirtualBox, we will have Fedora 33 support :)
The first I need to do is to disable libvirt to avoid any conflict and Update all packages (this was actually "a mistake" in my case, but nothing that can not be resolved)

Following the Guides mentioned earlier, we can get the VirtualBox RPM modified for Fedora 33 and ready to work

After VirtualBox was installed and I rebooted the system, I found the following errors when tried to build the Kernel Modules in my current Kernel 5.10.6-200.fc33.x86_64 (the new Kernel was one of the consequences of "dnf update" execution I did earlier)

The Log file was not very helpful to me, and reading around, and since VirtualBox has not support for Fedora 33 yet, I figured there is not support for new Kernel either
## Log file Building the main VirtualBox module.

At the end, I changed the grub2 default kernel and that made possible to get the Kernel modules set for previous version Kernel

Like I mentioned, I'm sure new VirtualBox version will start supporting Fedora 33 and latest Kernel versions, but until then, make sure you check compatibility before migrating to new Linux Distributions :)
