ProxMox is an excellent open-source server-virtualization management solution that runs virtual appliances and VMs.

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. 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. 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.
