So I'll just jump in here and ask for help. My VM broke after doing an update yesterday morning, and I haven't been able to figure out what happened. For reference here is my thead: my thread
Quick backstory: Started doing hardware passthrough almost a year ago. Been using it the entire time to play games on and off. System is an Asus Z170-A, i7-6700k, 32GB RAM. Host OS is Fedora 23. VM storage is a 128GB img file and a ~200GB img file for more (game) storage, both on a separate 1TB hard drive. Performance and stability have both been excellent.
After doing some troubleshooting (thanks to @The_Cable and @Deathright82 for the help) I am leaning towards the OVMF UEFI getting borked somehow. I know it updated, and both VMs that use it can't boot now.
Not really sure where to go next. Any help would be greatly appreciated.
edit: Oh, and the guide I used to set my passthrough up is here: link It is very similar to your @GrayBoltWolf guide.
