Information / Instructions for importing an OVA / OVF appliance from VirtualBox...

I'm looking for information or instructions for importing an OVA / OVF file created using VirtualBox into UTM for my M1 Mac users. This is an archive with a disk image (VDI/VMDK) and various configuration settings inside.

I'm kinda surprised not to see any mention of this in the repository at all.

I would imagine that even if it needed to be done "manually", one could extract the disk image, convert to qcow, and configure a new virtual instance to use it. I have used qemu in the past, though it would be difficult to walk my users through the process.

Any suggestions?
