What ZSvirt is
ZSvirt is an open-source, self-hosted virtualization platform built on ZStack’s ZSphere virtualization engine and using KVM. The site says a single control plane can manage 10,000+ hosts and virtual machines with up to 768 vCPUs. Its ZMigrate tool supports agentless VMware migration through full-disk replication, incremental synchronization, and cutover in as little as five minutes. Listed security features include VM SecureBoot, vTPM 2.0, VM encryption, security groups, MFA/2FA, a Native Key Provider, and immutable audit logs. For integrations, ZSvirt lists Go, Python, and Java SDKs, native Terraform providers, GitOps, and 2,000+ REST/OpenAPI endpoints. Compatibility options include distributed storage integrations, SAN support, the KVM ecosystem, VMDK, and mainstream hardware and guest operating systems. The open-source release has no license fee or VM limit and comes with community support. Enterprise adds advanced multi-cluster and compliance capabilities, LTS releases, SLAs, and vendor-backed production support. Downloads include x86_64 ISO, OVA, and QCOW2 images, as well as a ZMigrate package.
