It is designed to act as a hypervisor so as to provide well-defined management interfaces and APIs with minimum effort. OVirt Node is a dedicated lightweight operating system (OS) based on CentOS. VirtualBox is still the only truly free offering of the three and can be run on any edition of Windows 10 and may arguably still provide the best value out of the three solutions. It furthermore comes with virtualization disaster recovery and hyper-converged infrastructure (HCI) deployments features. It has difficulty in running on a single node. Its features also include support for virtual, isolated networks.

It works best with GlusterFS, but also supports many other storage backends too, namely- NFS, SCSI, FC, POSIX-compliant FS. OVirt (Open Virtual Datacenter) provides admin and non-admin users, both, with rich web-based user interfaces and also freedom of live VM migration between the host and storage. OVirt runs on Linux- Fedora, and CentOS, and Red Hat Virtualization (RHV) is based on the same. VirtualBox (Mac & Windows) If you are new to virtualization, then your best choice of using a virtual machine for the first time is definitely VirtualBox from Oracle.

Founded by Red Hat as a community project, oVirt is a free and open-source virtualization management platform with centralized, integrated “hosts, storage, and network” configuration management.
