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.
