In their own words
Apache CloudStack
Apache CloudStack is free, open-source software for deploying and managing networks of virtual machines as a highly available, scalable IaaS cloud platform. Organizations can use it to build public, private, or hybrid clouds. Its features include compute orchestration, network services, account management, resource accounting, a web interface, and an open API. Operators can manage clouds through a web UI, command-line tools, or REST API, with optional AWS EC2- and S3-compatible APIs. Supported hypervisors include XenServer or XCP, KVM, Hyper-V, and VMware ESXi with vSphere. Storage options include iSCSI, NFS, Ceph RBD with KVM, volume encryption, snapshots, and storage tiering. Authentication options include OAuth2 single sign-on, two-factor authentication, TOTP, SAML, and LDAP. The project says CloudStack can manage tens of thousands of physical servers across geographically distributed data centers. Long Term Support releases receive bug and security fixes for 18 months after the main release. Operators remain responsible for protections such as monitoring, host security, and defenses against DoS and brute-force attacks.
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.
