Cannot boot from EFI image on aarch64

[Ravishankar]

I am unable to boot from a EFI disk image on aarch64 qemu.

I have qemu built and installed from sources on a jetson-nano

qemu-system-aarch64 -version
QEMU emulator version 5.2.50 (v5.2.0-3234-gbdee969c0e)
Copyright (c) 2003-2021 Fabrice Bellard and the QEMU Project developers

KVM and and virtio are enabled in host kernel.

Now I want to boot a ChromiumOS image. I have the image downloaded from here:

https://chromium.arnoldthebat.co.uk/?dir=daily

The image looks fine:

rreddy78@jetson-nano:~/Downloads$ fdisk -lu chromiumos_image.bin

Partition table entries are not in disk order.

Now I try booting like this:

qemu-system-aarch64 -M virt -m 2048 -smp 2 -cpu host -enable-kvm \
-device usb-ehci -device usb-kbd -device usb-mouse -usb -serial stdio \
-device virtio-gpu-pci,virgl=on,xres=1600,yres=900 -display sdl,gl=on \

-drive if=none,file=chromiumos_image.bin,format=raw,id=hd \
-netdev user,id=mynet \
-device virtio-net-device,netdev=mynet \
-bios edk2-aarch64-code.fd -no-reboot

But I am unable to boot.

When i try to do it manually using the instructions provided here:

https://mricher.fr/post/boot-from-an-efi-shell/

I see that

BLK4 is not having any EFI file.

Hi,

This is not a bug with QEMU. Its a problem with ChromiumOS qemu image issue which does not have a valid EFI partition for booting on qemu with EDK2

Please close this ticket.
