> When the TianoCore logo showed (in the very beginning) I do not see the TianoCore logo when booting my DomU clients. The only time I can *recall* seeing it was "way back" when I installed the DomU. Which "beginning" are you referring to? Can I get BACK into the config menu for this existing Guest ? > I guess the guest booted with ovmf-x86_64-ms before so the MS keys were > written into NvVars. I'll try to reproduce the issue with my machine. Wouldn't the guest only boot with ovmf-x86_64-ms if it was SPECIFIED in the .cfg? My .cfg has always had bios_override = '/usr/share/qemu/ovmf-x86_64.bin' specified.
