I think this was about 32-bit GRUB builds used by distributions. I personally tested it with a kernel which has EFI support disabled, in this case the OVMF firmware will also boot into the startup_32 boot path. > By 'some firmware' we talking SeaBIOS? No, SeaBIOS is not supported for SEV-ES, only OVMF has handling for #VC so far. Regards, Joerg
