Dear All,

I use qemu and tianocore payload to research coreboot but I found qemu can not show vga message in bios post phase. I found tianocore function named“gST->ConOut->OutputString( )”can not show any string on qemu screen under bios post phase, I already add vbios named“vgabios-cirrus.bin”by“make menuconfig”,  anyone can tell me how to bring up qemu vga so that show gST->ConOut->OutputString( )”message on qemu screen under post time, my qemu setting as below :

qemu-system-x86_64 -machine accel=kvm:tcg -bios build/coreboot.rom -vga cirrus -m 2048 -drive file=/dev/sdb,index=0,media=disk,format=raw

P.S. My virtualbox does not install kvm

Best Regard
