I’m trying to install VirtualBox, but I don’t know how to do it. I was thinking about using Gnome Boxes or Virtual Machine Manager, but the problem is that I need to export and import the virtual machines, and they are in OVA format, and I don’t know how to do it. Can anyone help me?
You will need to either use a container which you’ve set up using BoxBuddy, or set up a new one.
You can then install VirtualBox in that container following the normal instructions:

Once you have the container, e.g. Debian or Fedora, you can then use the terminal to install it in that container like a normal distro.
Here’s an example of how someone does it on Bazzite, but the principle is the same on Bluefin or Aurora.

Regarding virtual machine image format conversion: I used this article on linuxconfig.org to convert VirtualBox OVA format to QCOW2 format. QCOW2 can be used to create virtual machines with QEMU/KVM or virt-manager which are available by default in DX flavours of Bluefin or Aurora. Not sure about Bazzite though.
