## What it is
ZSvirt is an open-source IaaS virtualization platform that brings ZStack's enterprise ZSphere engine to the community, providing a control plane for managing KVM-based virtual machines, hosts, storage, and networking. It positions itself as a lightweight, scalable VMware alternative supporting migration from vSphere and management of up to 10,000+ hosts from a single control plane.

## Use cases
- manage kvm virtual machines from a web dashboard
- migrate vmware vsphere workloads to open source
- build a self-hosted private cloud iaas
- replace vmware esxi for a homelab
- manage thousands of hypervisor hosts from one control plane
- provision vms with terraform
- monitor cpu memory and storage across a virtualization cluster

## When to choose
- you want an open-source VMware/vSphere alternative with migration tooling
- you need to manage large-scale KVM fleets from a single control plane
- you want enterprise virtualization features without vendor lock-in
- you prefer infrastructure-as-code via Terraform for VM provisioning

## When to avoid
- you only need lightweight container orchestration rather than full VMs
- you require a mature multi-cloud or public cloud management platform
- you need Windows or macOS hypervisor support
- you want a minimal single-node tool without a management plane

## Facets
- artifact type: application
