| Spec score · Virtualization Management Software | 8.7 (#3) | 8.1 (#8) |
| High availability | Highly available virtual machines can restart on another cluster host after host failure or other interruptions. | VM HA can automatically reboot virtual machines after host failure, with configurable global and cross-cluster policies. |
| Integrations | The feature catalog lists OVN/OpenStack providers, Glance, Cinder, GlusterFS, SR-IOV, OpenShift, Cloud-init and Terraform-related integrations. | The site lists SDKs for Go, Python, and Java, native Terraform providers, GitOps, and 2,000+ REST/OpenAPI endpoints. |
| License | oVirt uses Apache License 2.0 as its primary license, while some complementary projects may use LGPL or GPL. | The core project is released under the GNU GPL version 3.0. |
| Live migration | Running virtual machines can be moved between hosts in a cluster without service interruption. | The product supports hot and cold migration between hosts and across several local, NFS, SAN and distributed-storage combinations. |
| Networking | The current homepage identifies OVN networking as a built-in industry-standard foundation. | Networking includes virtual networks, distributed switches, distributed port groups, security groups, VLAN/VXLAN/flat topologies and SR-IOV. |
| Security controls | Official guidance requires HTTPS, SELinux, firewalls, security updates, individual administrator accounts and restricted host access. | Security features include Secure Boot, vTPM 2.0, VM encryption, security groups, MFA/2FA and immutable audit logs. |
| Self-hosting | The engine can run as a virtual machine in a self-hosted-engine deployment, while hosts can be oVirt Node or Enterprise Linux systems. | The management node can run on physical servers or as an OVA/QCOW2 virtual machine inside VMware, VirtualBox, KVM or a cloud host. |
| Storage | oVirt uses centralized storage for virtual machine disks, ISO files, and snapshots, with options including NFS, GlusterFS, iSCSI, local storage, Fibre Channel, pNFS, and other POSIX-compliant filesystems. | Storage capabilities include primary and backup storage, volumes, snapshots, image storage, local storage, NFS, SAN and distributed storage. |
| What it does | oVirt is a free, open-source distributed virtualization platform for managing enterprise infrastructure through a centralized interface. | ZSvirt is an open-source virtualization platform for managing virtual machines, clusters, hosts, storage and networks from a centralized control plane. |

In their own words
oVirt
oVirt is a free, open-source distributed virtualization system for managing enterprise infrastructure. It uses the KVM hypervisor and builds on community projects including libvirt, Gluster, PatternFly, and Ansible. Deployment options include a self-hosted Engine and a standalone Engine; the project recommends the self-hosted option, which runs as a virtual machine on specialized hosts and is highly available without external HA management. Centralized storage holds virtual machine disks, ISO files, and snapshots, with options including NFS, GlusterFS, iSCSI, local storage, Fibre Channel, pNFS, and other POSIX-compliant filesystems. Automation and integration are available through Ansible roles and collections, Python, Java, and Ruby SDKs, and a REST API. The download page identifies version 4.5.7 as intended for production use, with Engine and host support for Enterprise Linux 9 or 10 and CentOS Stream 9 or 10. Installation is by command line. At least one additional host is required for advanced features such as migration and high availability. The project points users to community forums, IRC, and Matrix, and invites contributions.
ZSvirt
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.
