A Kubernetes operator of virtual BMCs that provide Redfish and IPMI services for KubeVirt virtual machines.
Bare-metal provisioning tools like Metal3, Tinkerbell, and Seeder rely on IPMI and Redfish to manage server power state, boot devices, and firmware. KubeVirt virtual machines have none of these interfaces out of the box, making them invisible to existing infrastructure automation.
KubeVirtBMC fills that gap. It is a Kubernetes operator that creates a virtual BMC (Baseboard Management Controller) for each KubeVirt VM, exposing standard IPMI and Redfish endpoints that map directly to Kubernetes-native operations. The result: your VMs become first-class citizens in any bare-metal provisioning pipeline.

Exo is an agent + harness architecture that is fully recursive, able to safely edit all aspects of itself at runtime to get better at your tasks.
exoharness is a minimal architecture for building agents. It separates trusted infrastructure for state, resources, and security from agent-specific logic that can evolve, stop, resume, and rewind across runs.
Exo is a systems approach to recursive self improvement. In short, it's a complete AI agent harness (supporting tools, tasks, integrations, etc. similar to OpenClaw, Pi or Hermes), with the crucial difference that it has full visibility into both its code and runtime logs. This allows Exo to incrementally improve every aspect of itself, clone itself, and even manage a lineage of clones.
