This is often the case when bringing new images online, that some changes to DIB
will be required to support them. I suspect somebody with access to AArch64
hardware will first need to run build-image.sh[1] and paste the build.log. That
will build an image locally for you using our DIB elements.

I don't believe we want to look at using a new tool to build all our images,
switching to virt-install would be a large change. There are reasons why we
build images from scratch and don't believe switching to virt-install help
with that.
