When I was testing on the packet c2.arm instances I didn't hit any
issues, it pretty much "just worked".

How well do things work when you build arm64 images native on arm64?

built the cosa container image locally on qemu using the dockerfile and now I am trying to
generate the VM images (arm64) following the steps mentioned in the readme (cosa init,
cosa fetch and cosa build). But the cosa project however has a pre-req that it needs
access to virtualization /dev/kvm.

cannot use KVM on QEMU and therefore cannot use it within the container. Is there a way to
disable the KVM option? If yes, can you guide me a little to understand how this can be
done.

see
