Proxmox VE
Open-source virtualization platform (KVM + LXC) with a web management UI — the most-used self-hosted alternative when migrating off VMware, positioning it as the open-source counterpart to VMware_Cloud_on_AWS's migration target, though actual VM re-platforming (not lift-and-shift compatibility) is required. OpenStack is the alternative at larger, multi-tenant private-cloud scale.
