| Fact | oVirt | ZSvirt |
|---|---|---|
| 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. |
oVirt suits organizations managing enterprise infrastructure that can install and operate a self-hosted virtualization system. It is also relevant to teams needing APIs, automation tools, or centralized storage choices.
ZSvirt suits self-hosting users ranging from homelab operators to large infrastructure teams, including organizations moving away from VMware. The open-source edition may suit users who can rely on community support rather than vendor-backed production support.
