Score: 7.0/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 6)

Holos is a Docker Compose-like tool for managing multi-VM stacks using KVM/QEMU, allowing users to define virtual machine clusters in a single YAML file with cloud-init provisioning. It's interesting because it brings container orchestration semantics to full VMs while avoiding libvirt complexity and distributed control planes, making KVM more accessible for local development and testing scenarios.

Target audience: devops, backend devs, infrastructure engineers
