This hasn’t happened to me yet but I was just thinking about it. Let’s say you have a server with an iGPU, and you use GPU passthrough to let VMs use the iGPU. And then one day the host’s ssh server breaks, maybe you did something stupid or there was a bad update. Are you fucked? How could you possibly recover, with no display and no SSH? The only thing I can think of is setting up serial access for emergencies like this, but I rarely hear about serial access nowadays so I wonder if there’s some other solution here.
How’s the disk encrypted? I’ve never heard of anyone setting up an encrypted drive such that you can’t manually mount it with the password. It’s possible but you’d have to go out of your way to do that and only encrypt the drive with a TPM-managed key. It’s kind of a bad idea because if you lock yourself out your data’s gone.
I was confused on how secure boot and disk encryption worked, ignore me 😅
