Can't boot Fedora Cloud and CoreOS images

[srprca]

Hello!

I have been trying booting Fedora Cloud and Fedora CoreOS images, after unpacking both and converting the CoreOS image from .qcow2 to .raw, using the following commands:

For Fedora Cloud:

cloud-hypervisor --kernel ./hypervisor-fw --disk path=./Fedora-Cloud-Base-AmazonEC2-43-1.6.x86_64.raw --cpus boot=4 --memory size=1024M --serial tty --console off

It doesn't start, and I see the following output:

Both images start fine if I use edk2 UEFI firmware from here.
