| High availability | Highly available virtual machines can restart on another cluster host after host failure or other interruptions. | Proxmox VE includes a high-availability manager that monitors virtual machines and containers and acts automatically when one fails. |
| Live migration | Running virtual machines can be moved between hosts in a cluster without service interruption. | Running virtual machines can be moved between cluster nodes through the web interface or command line without noticeable end-user downtime. |
| Security controls | Official guidance requires HTTPS, SELinux, firewalls, security updates, individual administrator accounts and restricted host access. | The platform provides a distributed IPv4/IPv6 firewall, granular ACLs, API tokens, UEFI Secure Boot, and virtual TPM support. |
| What it does | oVirt is a free, open-source distributed virtualization platform for managing enterprise infrastructure through a centralized interface. | Proxmox VE is an open-source server virtualization platform that manages KVM virtual machines and Linux Containers through one web interface. |

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.
Proxmox VE
Proxmox VE is an open-source, self-hosted server virtualization platform that manages KVM virtual machines and Linux Containers from an integrated web interface. A bare-metal installation includes a 64-bit Debian GNU/Linux operating system with a Proxmox kernel; installation uses the selected server and removes existing data on selected disks. Administrators can also manage the system through a command-line interface and REST API. The cluster stack supports multi-node management from any node, with high availability monitoring and automatic action when a VM or container fails. Running VMs can migrate between cluster nodes without noticeable end-user downtime. Storage options include NFS, SMB/CIFS, iSCSI, Ceph, GlusterFS, LVM, ZFS and directory storage. Proxmox Backup Server integration provides incremental encrypted backups, live restore and single-file recovery. The software is free to download under GNU AGPLv3. Paid subscriptions are per occupied physical CPU socket; each cluster server needs coverage at the same subscription level. The maker is Proxmox Server Solutions GmbH, founded in 2005 and headquartered in Vienna, Austria.
