Hi everyone and Martin 

I would like to confirm the conversation we had in regard the possible limitation of firmware auto-select feature that’s been released since v5.20.  I recall you saying that there were a lot of issues with auto select and later they shipped it into a Json file , it  still didn’t solve all the problems, did it?

Is it better to explicitly specify the loader and nvram path than using auto-select ?

Just today, I encountered the issue of using firmware=“efi” on libvirt 5.4.0 

I am running Ubuntu eoan 19.10, I am wondering how did it happen.

Detailed error 
Error starting domain: internal error: process exited while connecting to monitor: 2020-05-15T14:19:06.033267Z qemu-system-x86_64: -drive file=/usr/share/OVMF/OVMF_CODE.fd,if=pflash,format=raw,unit=0,readonly=on: Failed to lock byte 100
