Red Hat Virtualization 4.4 is past maintenance and its Extended Life Phase ends in August 2026. Pages here cover moving to oVirt, KubeVirt, Proxmox VE or OpenStack.
For RHV customers whose Extended Life Phase is ending: what oVirt, the upstream community project, keeps from RHV, what changes without Red Hat support, supported host operating systems, release activity, and who supports it in production.
Comparing RHV's engine and KVM hosts with Proxmox VE: clustering, storage domains against Ceph or ZFS, management and APIs, Proxmox subscriptions per socket, and the migration effort from RHV storage domains.
For larger RHV estates that need multi-tenancy or self-service: comparing RHV data centers and clusters with an OpenStack cloud on Ceph, networking with Neutron and OVN, the team needed to operate it and how VMs move across.
Moving from RHV 4.4 to the community oVirt 4.5 line: host and engine operating system changes, self-hosted engine installation, moving storage domains and VMs, and testing the result before Red Hat's Extended Life Phase ends.
Moving RHV VMs onto Kubernetes with Forklift: setting up the oVirt-compatible source provider, network and storage mappings, warm migration to cut downtime, and the Kubernetes storage needed for live migration afterward.
Moving RHV VMs to Proxmox VE: exporting VMs or disks from RHV storage domains, importing with qm importovf or qm disk import, guest agent and driver changes, networking, and sequencing the move cluster by cluster.
RHV 4.4 maintenance ended on August 31, 2024 and its Extended Life Phase, with no software fixes, ends on August 31, 2026. This page compares OpenShift Virtualization, oVirt, KubeVirt, Proxmox VE and OpenStack as destinations and plans the exit.
