Virtuozzo: Container-Based Virtualization with Enterprise Roots General Overview Virtuozzo is a commercial platform that delivers container-based and virtual machine workloads through a single hypervisor. It originated as a fork of OpenVZ and was one of the first technologies to offer operating system–level virtualization for Linux — long before Docker or LXC became mainstream.

Today, Virtuozzo has evolved into a hybrid solution that combines KVM-based virtualization with its own container engi

Xen Project: A Hypervisor That Prioritizes Isolation Over Convenience General Overview Xen Project is one of those tools that’s been around long enough to feel both battle-tested and a bit niche. It’s not built for plug-and-play setups or fancy web dashboards. It’s built for control. The kind of control that people running infrastructure really care about — especially when security, performance, or both are non-negotiable.

This is a type-1 hypervisor, meaning it runs directly on bare metal. No

Parallels Desktop: macOS-Centric Virtualization with Native UX Priorities General Overview Parallels Desktop is a virtualization platform purpose-built for macOS. Unlike generic hypervisors, it doesn’t try to be cross-platform — instead, it focuses entirely on tight integration with Apple’s ecosystem. The goal is simple: run Windows, Linux, or other OSes on a Mac without forcing the user to leave the macOS environment.

Where tools like VirtualBox feel generic and disconnected, Parallels behaves
