zsvirt

ZSvirt is a full virtualization platform: install it on bare metal and it manages VMs, virtual networks, storage, snapshots, and live migration from one web console. Same job VMware vSphere does, at GPL-3.0 and zero license cost. ZStack, an infrastructure vendor that sells a commercial product called ZSphere, took that engine and open sourced it in August 2026.

This is not a Docker pull. You are standing up a hypervisor cluster: hosts, primary and backup storage, network configuration, then the management plane on top. Budget real time for a first cluster and someone who knows KVM and Linux networking for when it breaks. The VMware migration tooling is the most interesting piece, and the part most likely to surprise you on a production fleet.

Homelab and solo: worth a look, though Proxmox VE has a decade of community answers behind it and ZSvirt has weeks. Small teams: only if someone owns infrastructure as an actual job. Shops reassessing VMware licensing: a legitimate evaluation candidate, and having a vendor with production customers behind the code matters here.

The repo went public in August 2026 with a handful of commits. The engine has enterprise mileage; the open source project does not. Governance docs exist, a maintainer community does not yet. Lab it, do not bet the cluster your business runs on until the release cadence proves itself.
