Proposed: Evaluate Nutanix Community Edition and Harvester HCI for Development Infrastructure
The Context
The development team needs to evaluate hypervisor solutions for remote infrastructure management. Two primary options are being considered: Nutanix Community Edition (enterprise-grade with community licensing) and Harvester HCI (fully open-source hyperconverged infrastructure). Both should enable easy administration over the internet while maintaining portability to cloud-native deployments, with support for container deployment and cloud-init for development workflows.
The Problem Statement
Current infrastructure lacks a standardized hypervisor solution for development and testing environments that balances ease of remote administration with the requirement for portability and open-source alternatives.
Design
Evaluate two hypervisor solutions for development infrastructure:
Option 1: Nutanix Community Edition
- Install on bare metal or VMs (up to 4 nodes free)
- Web-based management interface for remote administration
- Built-in container and cloud-init support
- Can run on developer laptops for local testing
Option 2: Harvester HCI
- 100% open-source hyperconverged infrastructure solution
- Built on Kubernetes, KubeVirt, and Longhorn
- Modern HCI using enterprise-grade open-source technologies
- Single pane of glass for virtualization and container management
Both options provide:
- Remote administration capabilities over internet
- Container workload support
- Cloud-init integration for automated deployments
- Portability to cloud-native architectures when scaling
Infrastructure Design:
Hypervisor Layer (Nutanix/Harvester)
↓
Container/Application Layer (K3s, Docker, etc.)
↓
Development Applications (V-Sekai, etc.)The Benefits
- Both solutions provide web-based interfaces for internet-accessible management
- Native support for containers and cloud-init simplifies deployment workflows
- Both can run on developer laptops or VMs for local testing environments
- Free community/open-source licensing for development use
- Harvester provides a fully open-source alternative to Nutanix’s hybrid model
- Applications remain deployable on cloud platforms without hypervisor dependencies
- Built on proven open-source technologies (Linux, KVM, Kubernetes)
The Downsides
Nutanix Community Edition
- Not fully open source (built on proprietary enterprise software)
- Vendor dependency concerns for enterprise software
- Limited to 4 nodes in Community Edition
- Potential future licensing changes
Harvester HCI
- Newer project compared to established enterprise solutions
- May have fewer third-party integrations than mature platforms
- Requires Kubernetes knowledge for advanced management
- Community support vs enterprise backing
Both Options
- Learning curve for hypervisor management
- Resource overhead compared to container-only solutions
The Road Not Taken
- Proxmox only: viable, but lacks the integrated HCI features and container management capabilities of both Nutanix and Harvester
- Cloud-only: would sacrifice local development environments and easy remote administration
- Custom hypervisor solution: would require significant development effort for features already available in mature open-source solutions
- Proprietary-only: no open-source fallback
The Infrequent Use Case
- Large-scale production: when infrastructure exceeds 4 nodes or requires enterprise support beyond Community Edition
- Air-gapped environments: where internet-based administration tools cannot be used
- Minimal resource scenarios: where hypervisor overhead is unacceptable for resource-constrained deployments
In Core and Done by Us
Infrastructure tooling decisions are core to development workflow efficiency. The development team will handle evaluation, documentation, and implementation of both primary and fallback hypervisor solutions.
Status
Status: Obsolete — Harvester HCI/Nutanix evaluation obsolete; current dev infrastructure uses different approach

Infrastructure Jargon
- Hypervisor: Software that creates and manages virtual machines, allowing multiple operating systems to run on a single physical machine.
- HCI (Hyper-Converged Infrastructure): Integrates compute, storage, and networking into a single, software-defined platform.
- Cloud-Init: Multi-distribution package that handles early initialization of cloud instances, supporting configuration of hosts immediately after instantiation.
- Bare Metal: Running software directly on physical hardware without virtualization layer.
