Steps To ReproduceConvert image to raw for import
    # qemu-img convert ./CentOS-8-ec2-8.1.1911-20200113.3.x86_64.qcow2 ./CentOS-8-ec2-8.1.1911-20200113.3.x86_64.raw
Upload to S3 for import
    # aws s3 cp ./CentOS-8-ec2-8.1.1911-20200113.3.x86_64.raw s3://<my_bucket>/
Import the raw image to snapshot
    # aws ec2 import-snapshot --client-token CentOS8 --description "Import Base CentOS8 Image" --disk-container "Description=CentOS-8-ec2-8.1.1911-20200113.3.x86_64.raw,Format=raw,UserBucket={S3Bucket=<my_bucket>,S3Key=disk-images/CentOS-8-ec2-8.1.1911-20200113.3.x86_64.raw}"
Register the image
    # aws ec2 register-image --architecture=x86_64 \
    --virtualization-type hvm \
    --description='CentOS 8 (x86_64) for HVM Instances' \
    --root-device-name '/dev/sda1' \
    --name='CentOS-8-ec2-8.1.1911-20200113.3.x86_64' \
    --ena-support --sriov-net-support simple \
    --block-device-mappings "[{\"DeviceName\": \"/dev/sda1\", \"Ebs\": {\"DeleteOnTermination\":true, \"SnapshotId\":\"snap-0194fe89d00xxxxxx\", \"VolumeSize\":10, \"VolumeType\":\"gp2\"}}]"

Now Launch an instance from the created image.

It looks like this section of the kickstart file is not being run, or has an error:

echo 'add_drivers+="xen-netfront xen-blkfront "' > /etc/dracut.conf.d/xen.conf
# Rerun dracut for the installed kernel (not the running kernel):
KERNEL_VERSION=$(rpm -q kernel --qf '%{V}-%{R}.%{arch}\n')
dracut -f /boot/initramfs-$KERNEL_VERSION.img $KERNEL_VERSION

This is from:

I pulled down the EC2 image from

loop back mounted the image, and chroot'd to it. I then ran the above commands. After tearing down the loopback mount, I was able to register an AMI using the updated image, and run the AMI.

Yes, and as you saw , it's fixed for 2 months in git, but it's just that there was no cloud image compose (probably now waiting on 8.2.2004) so hopefully that will be fixed soon
Relevant commits :
- (for aarch64 that needs also EFI part)

This is resolved with the availability of the 8.2.2004 images.
