# ZSvirt Community Edition

> A production-ready, lightweight open-source virtualization platform for environments from homelabs to hyperscale infrastructure.

ZSvirt brings ZStack's enterprise-proven ZSphere virtualization engine into the open-source world. Backed by ZStack, a mature infrastructure leader, ZSvirt delivers a lightweight, scalable platform designed for absolute freedom—from high-performance homelabs to hyperscale infrastructure without vendor lock-in.

## Production-grade virtualization, built for the community

From performance, security, and migration to open automation, ZSvirt organizes virtualization capabilities for real production environments.

## Performance & Scale

Run your heaviest workloads on a lightweight, highly optimized open-source virtualization stack.

### Virtualization at Massive Scale

Built to manage up to 10,000+ hosts seamlessly from a single control plane, with VMs up to 768 vCPUs.

### Enhanced Compute Efficiency & VM Density

Deliver up to a 3.8x increase in VM density and a 3x leap in Performance per Watt.

### Accelerated Virtual Networking

SR-IOV delivers up to a 60x throughput leap over traditional Linux Bridge and supports SR-IOV Live Migration.

## Seamless VMware Migration

Migrate away from vendor lock-in with an open, non-intrusive migration pipeline.

### Continuous Migration Sync

Perform full-disk block replication and background incremental syncs without interrupting live operations.

### 100% Agentless Migration

The built-in ZMigrate toolset runs entirely at the hypervisor level with no guest agents required.

### Fast Migration Cutover

Complete cutover in as little as 5 minutes to maximize business continuity.

## Built-in Security

Secure your environment from bare metal to network traffic with open, verifiable trust.

### Built-in Key Security (NKP)

Manage encryption keys with the built-in Native Key Provider without external dependencies.

### Hardware-Level Security & Encryption

Native VM SecureBoot, vTPM 2.0, and native VM Encryption protect sensitive workloads.

### Security Micro-segmentation & Audit

Security groups isolate east-west traffic to prevent lateral attacks, while MFA/2FA and immutable audit logs keep infrastructure compliant.

## Open by Design

No artificial limits. Automate and extend your infrastructure with total developer freedom.

### Open Multi-Language SDKs

Integrate with Kubernetes, PaaS, or internal platforms using SDKs for Go, Python, and Java.

### Open IaC & GitOps

Automate provisioning with native Terraform providers.

### Open, Fully Asynchronous APIs

Expose 2,000+ production-ready RESTful/OpenAPI endpoints for granular resource control.

## Best Practices

Explore two practical workflows: fast deployment for launching a production dashboard instantly, and live migration for moving workloads without losing a single ping.

- [Fast Deployment](https://oss.zstack.io/product_downloads/ZSvirt/video/Install%20ZSvirt.mp4): Copy, paste, and run. See how our lightweight architecture spins up a full production dashboard instantly.
- [Live Migration](https://oss.zstack.io/product_downloads/ZSvirt/video/ZMigrate.mp4): Shift away from vendor lock-in. Watch a live database migrate to zsphere without losing a single ping. within few minutes
