Hey @markhuang5305 , we do provide instructions on how to build your own image from the bottlerocket sources. You can have a look at:

• PROVISIONING METAL
• QUICKSTART LOCAL

For examples of how to use the .img files and you can provision the user data you need to let them join your cluster.

Additionally, you can build your own variants, you only need your own image definition. See variants.

Yes, you can test Bottlerocket in QEMU/KVM without EKS or ECS, but the documented local route is a built metal-dev disk image, not an ISO installer. The project's QEMU/KVM quickstart says to build the metal-dev variant (see BUILDING.md, using -e BUILDSYS_VARIANT=metal-dev with cargo make), then start it with the repository helper:

./tools/start-local-vm --variant metal-dev --arch "$(uname -m)" --inject-file net.toml

The quickstart gives the required net.toml example and optional user-data.toml/host-container setup. It explicitly says this local VM does not join a Kubernetes or ECS cluster and is meant for testing/development.

If you need a production Kubernetes node on KVM, that is a different question: the current README variant list lists EKS and VMware Kubernetes variants, and marks the old bare-metal Kubernetes variants unsupported. I would not assume an EKS image or an old metal image is a supported generic KVM node. Tell us whether you only want to try the OS locally or need it to join a specific Kubernetes cluster, and which Bottlerocket version/architecture you need.
