Architecture

ZSvirt uses a modular architecture built around virtualization resource management, the management plane, extension services, and operational tooling.

Core capabilities include:

Compute virtualization: host, cluster, virtual machine, image, and lifecycle management.
Network virtualization: virtual networks, network services, security groups, and related capabilities.
Storage virtualization: primary storage, backup storage, volumes, snapshots, and storage resource management.
Management plane: API framework, permission model, events, alarms, auditing, and system operations.
Extension services: capabilities for migration, disaster recovery, monitoring, quota management, access control, and enterprise operations.
Tools and integrations: installation tools, diagnostics tools, migration tools, automation scripts, agents, CLI, and external system integrations.

At the software architecture level, ZSvirt emphasizes asynchrony, statelessness, extensibility, and automation:

Asynchronous architecture: supports asynchronous messages, asynchronous methods, and asynchronous HTTP calls to reduce blocking and improve system throughput.
Stateless services: individual requests do not depend on state from other requests, making services easier to scale, recover, and operate.
Plugin-based extensibility: supports horizontal extension of resource types, business capabilities, and integration capabilities through plugins.
Workflow engine: manages the execution order of complex operations and supports rollback and recovery in failure scenarios.
Tagging and query capabilities: supports resource attribute extension, resource classification, unified queries, and automation orchestration.
Automated deployment: uses automation tools to handle deployment, configuration, and operations tasks, reducing deployment and maintenance complexity.

VMware Migration Guide

As enterprises reassess their virtualization strategies, migration from VMware to alternative platforms has become an important topic for organizations seeking cost control, infrastructure flexibility, and long-term operational stability.

ZSvirt provides migration-oriented capabilities and operational tools to help users evaluate, plan, and move workloads from existing VMware environments to ZSvirt-based virtualization infrastructure.

Governance

ZSvirt is governed by a lightweight open-source governance model that defines how the project is maintained, how decisions are made, and how contributors collaborate.

The GOVERNANCE.md document is the starting point for learning about project roles, maintainer responsibilities, decision-making processes, release management, and community collaboration.

As the community grows, the governance model may evolve to include dedicated maintainers, working groups, and more formal project processes.
