ZSvirt

ZSvirt is an open-source virtualization platform built on KVM that covers compute, network, and storage: hosts and clusters, virtual machines, images, virtual networks, security groups, volumes, and snapshots. The management plane adds an API framework, a permission model, events, alarms, and auditing, and VMware migration tooling for online migration, OVF import, and VMDK upload is built in. A hosted demo runs without installation, and downloadable qcow2 or OVA images boot inside an existing hypervisor. Written in Java and released under GPL-3.0.
