Proxmox VE is an open-source server virtualization platform to manage two virtualization technologies: Kernel-based Virtual Machine (KVM) for virtual machines and LXC for containers - with a single web-based interface. [11]
OpenVMS, often referred to as just VMS, [8] is a multi-user, multiprocessing and virtual memory-based operating system.It is designed to support time-sharing, batch processing, transaction processing and workstation applications. [9]
OpenVZ (Open Virtuozzo) is an operating-system-level virtualization technology for Linux. It allows a physical server to run multiple isolated operating system instances, called containers, virtual private servers (VPSs), or virtual environments (VEs). OpenVZ is similar to Solaris Containers and LXC.
Oracle VM Server for x86 is a server virtualization offering from Oracle Corporation. Oracle VM Server for x86 incorporates the free and open-source Xen hypervisor technology, supports Windows , Linux , and Solaris [ 3 ] guests and includes an integrated Web based management console.
The Open Source Initiative has approved this as "Open Source" [32] but the Free Software Foundation and the Debian Free Software Guidelines do not consider it "free". [31] [33] VirtualBox has experimental support for macOS guests. However, macOS's end user license agreement does not permit running on non-Apple hardware.

Xen Project runs in a more privileged CPU state than any other software on the machine, except for firmware.. Responsibilities of the hypervisor include memory management and CPU scheduling of all virtual machines ("domains"), and for launching the most privileged domain ("dom0") - the only virtual machine which by default has direct access to hardware.
OS-level virtualization is an operating system (OS) virtualization paradigm in which the kernel allows the existence of multiple isolated user space instances, including containers (LXC, Solaris Containers, AIX WPARs, HP-UX SRP Containers, Docker, Podman), zones (Solaris Containers), virtual private servers (), partitions, virtual environments (VEs), virtual kernels (DragonFly BSD), and jails ...
