Parallels Desktop vs Xen Project Hypervisor

Parallels Desktop runs Windows and Linux virtual machines on a Mac, so users can run Windows applications alongside macOS. Supported hosts include Intel Macs running macOS Catalina 10.15 or later and Apple Silicon Macs running macOS Big Sur 11 or later. It is authorized by Microsoft for Windows 11 on Apple Silicon and supports current macOS, Windows, and Linux versions. Listed Windows applications include Excel, Power BI, Access, and QuickBooks. Virtual machines support snapshots, nested virtualization, and GPU acceleration. Standard permits up to 8 GB of vRAM and four vCPUs per VM; Pro raises those limits to 128 GB and 32 vCPUs. Pro also supports command-line workflows and Jenkins and Vagrant integrations. Business adds centralized administration, license management, and Jamf and Intune deployment integrations, while Enterprise includes encrypted VMs under organizational control. The product is paid and offers a 14-day trial. Standard and Pro include unlimited phone and email support, and subscribers get 24/7 chat. Qualifying direct purchases have a 30-day money-back guarantee; renewals are excluded.

Xen Project Hypervisor is a free, open-source type-1 hypervisor that runs multiple operating systems on one host. The project describes uses including server and desktop virtualization, IaaS, embedded systems, security applications, and hardware appliances. Linux is the most common control stack; NetBSD and FreeBSD are also named as host options. Xen’s microkernel design has a small memory footprint and restricts the interface exposed to guests. It can run a system’s main device driver inside a VM, allowing that VM to be restarted after a driver crash or compromise without affecting the rest of the system. On x86, fully paravirtualized guests can run without virtualization extensions. Listed capabilities include snapshots, nested virtualization, and GPU acceleration. The separate XAPI toolstack supports multi-host management, snapshots and migration, resource pools, storage migration, Open vSwitch, event tracking, upgrades, patching, and monitoring. Its built-in guest support and templates cover Windows and Linux. Downloads are source releases for building, packaging, and platform integration.
