 When downloading virtual machines they're usually packaged in an OVA file (Open Virtual Appliance). An OVA file is actually just a single file archive with an OVF package inside.  
 An OVF package contains the metadata decribing the virtual machine (usually a .ovf file) and the virtual disks. The OVF standard doesn't specify a disk image format.

 I have a corsair void pro wireless at my desk, this headset is quite old but it still works so I keep it. I just changed the earpads and head cushioning since I bought it. But it was the only peripheral I have at my desk forcing me to always have a micro USB cable laying around somewhere to charge it every now and then. So recently I decided to upgrade the charging port of my corsair void pro wireless headset from micro USB to USB C.

 On my server I self host Overleaf with containers (podman) and Overleaf requires MongoDB as a database. Each version of Overleaf has a minimum required version of MongoDB and therefore you might have to upgrade your MongoDB container at one point. I'll explain step by step how I did it in my case.
