What it is

ZSvirt is an open-source, self-hosted virtualization platform based on ZStack’s ZSphere virtualization engine. It uses KVM and the site says one control plane can manage 10,000+ hosts, with VMs of up to 768 vCPUs. The ZSvirt Open Source plan has no license fee and no VM limit; it is offered with community support. Live migration, high availability, disaster recovery and API access are listed capabilities.

For VMware migration, ZMigrate supports agentless full-disk replication, incremental sync and cutover in as little as five minutes. Listed security features include VM SecureBoot, vTPM 2.0, encryption, security groups, MFA/2FA and immutable audit logs. Integration options include Go, Python and Java SDKs, native Terraform providers, GitOps and 2,000+ REST/OpenAPI endpoints. Storage and compatibility options include distributed storage integrations, SAN support, the KVM ecosystem, VMDK, and mainstream hardware and guest operating systems. Downloads include x86_64 ISO, OVA and QCOW2 images, plus the ZMigrate package. Enterprise adds advanced multi-cluster and compliance capabilities, LTS releases, SLAs and vendor-backed production support.
