OpenPOWER Host OS is an open community for OpenPOWER hardware enablement and features that is built on top of a reference host operating system and Kernel-based virtual machine (KVM) for Power.

As new OpenPOWER hardware features and servers are developed by multiple partners, it is challenging to deploy them in an OS environment that uses a known and tried base and, at the same time, allows for the flexibility needed to support diverse requirements. To address this challenge, IBM is launching a new collaboration model: An open community for OpenPOWER hardware enablement and features that is built on top of a reference host OS or Kernel-based virtual machine (KVM) for Power.

Through this community, IBM provides an open source repository that is seeded with the core elements for creating an successful OpenPOWER implementation. This allows OpenPOWER partners to build and validate their own deliverables. This repository includes the core Linux kernel as well as other key component pieces to enable KVM virtualization, along with build scripts, and a validation suite. These components enable members of the OpenPOWER ecosystem to build their own host OS with the optional support of KVM on Power. Most importantly, users are able to contribute back to this community.

Even further, an additional usage model that this repository provides is an abstraction layer that is based upon KVM virtualization. This option allows OpenPOWER partners to deploy new hardware features and servers while maintaining a stable environment for guest Operating Systems.  

While IBM remains committed to each respective upstream community, this new community will help all to advance the OpenPOWER ecosystem and ensure some feature consistency.

Why should I contribute?

These components enable members of the OpenPOWER ecosystem to build their own host OS with the optional support of KVM on Power and, most importantly, allow them to contribute back to this community.

What business problem will the new project address?

As new OpenPOWER hardware features and servers are developed by multiple partners, it becomes a challenge to deploy them in an OS environment that leverages a known and tried base and, at the same time, allows for the flexibility that is required to support the diversity of requirements.
