WandLinux is an Ubuntu-based system using the Linux kernel designed to run a Linux environment natively on Windows systems. It is FOSS being released under the GNU GPL license. It uses the coLinux kernel to run, Xming to run X Window, PulseAudio for sound, and has the option of either using a stripped down version of KDE or Xfce.
WCherryOS was a PowerPC G4 processor emulator for x86 Microsoft Windows platforms, which allowed various Apple Inc. programs to be operated on Windows XP. Announced and made available for pre-orders on October 12, 2004, it was developed by Maui X-Stream (MXS), a startup company based in Lahaina, Hawaii and a subsidiary of Paradise Television. The program encountered a number of launch difficulties its first year, including a poorly-reviewed soft launch in October 2004, wherein Wired Magazine argued that CherryOS used code grafted directly from PearPC, an older open-source emulator. Lead developer Arben Kryeziu subsequently stated that PearPC had provided the inspiration for CherryOS, but "not the work, not the architecture. With their architecture I'd never get the speed."
WCHIP-8 is an interpreted programming language, developed by Joseph Weisbecker. It was initially used on the COSMAC VIP and Telmac 1800 8-bit microcomputers in the mid-1970s. CHIP-8 programs are run on a CHIP-8 virtual machine. It was made to allow video games to be more easily programmed for these computers.
WCooperative Linux, abbreviated as coLinux, is software which allows Microsoft Windows and the Linux kernel to run simultaneously in parallel on the same machine.
WCP-67 was the control program portion of CP/CMS, a virtual machine operating system developed for the IBM System/360-67 by IBM's Cambridge Scientific Center. It was a reimplementation of their earlier research system CP-40, which ran on a one-off customized S/360-40. CP-67 was later reimplemented (again) as CP-370, which IBM released as VM/370 in 1972, when virtual memory was added to the System/370 series. Details on the development and circumstances of CP-67 can be found in the article History of CP/CMS.
WdbDOS is software developed by dBase for Windows computers with Intel processors. dbDOS allows Intel-based PCs to run DOS Applications, such as dBASE III, dBASE IV, and dBASE V for DOS in an emulated DOS environment. It is an environment configured specifically to allow the various versions of dBASE for DOS to run without any changes to the dBASE executables or the dBASE compiled programs created.
WFlatpak is a utility for software deployment and package management for Linux. It is advertised as offering a sandbox environment in which users can run application software in isolation from the rest of the system.
WGaneti is a virtual machine cluster management tool originally developed by Google. The solution stack uses either Xen, KVM, or LXC as the virtualization platform, LVM for disk management, and optionally DRBD for disk replication across physical hosts or shared storage for external replication. Since 2007 Ganeti is developed and released as free and open-source software. Originally subject to the requirements of the GNU General Public License (GPL) version 2, the license was changed to the 2-clause BSD license in version 2.11.6, released September 2014.
WCP-40 was a research precursor to CP-67, which in turn was part of IBM's then-revolutionary CP[-67]/CMS – a virtual machine/virtual memory time-sharing operating system for the IBM System/360 Model 67, and the parent of IBM's VM family. CP-40 ran multiple instances of client operating systems – particularly CMS, the Cambridge Monitor System, built as part of the same effort. Like CP-67, CP-40 and the first version of CMS were developed by IBM's Cambridge Scientific Center (CSC) staff, working closely with MIT researchers at Project MAC and Lincoln Laboratory. CP-40/CMS production use began in January 1967. CP-40 ran on a unique, specially modified IBM System/360 Model 40.
WKernel-based Virtual Machine (KVM) is a virtualization module in the Linux kernel that allows the kernel to function as a hypervisor. It was merged into the mainline Linux kernel in version 2.6.20, which was released on February 5, 2007. KVM requires a processor with hardware virtualization extensions, such as Intel VT or AMD-V. KVM has also been ported to other operating systems such as FreeBSD and illumos in the form of loadable kernel modules.
WMarionnet is a virtual network laboratory: it allows users to define, configure and run complex computer networks without any need for physical setup. Only a single, possibly even non-networked Linux host machine is required to simulate a whole Ethernet network complete with computers, routers, hubs, switches, cables, and more Support is also provided for integrating the virtual network with the physical host network.
WThe Open Virtualization Alliance (OVA) was a Linux Foundation Collaborative Project committed to foster the adoption of free and open-source software virtualization solutions including KVM, but also software to manage such, e.g. oVirt. The consortium promoted examples of customer successes, encouraged interoperability and accelerated the expansion of the ecosystem of third party solutions around KVM.
WPano Logic was a manufacturer of devices which present virtual desktops to the end user with no local processing power. They describe this concept as "zero client". This is perceived as offering benefits in end-user support and in power provision to desks. OEM versions have been included in displays from some vendors, allowing a single unit to be deployed. The company failed in October 2012. In March 2013, Propalms announced they had acquired the rights to support Panologic customers, and will "help transition the customer base to a new platform".

WA virtual file system (VFS) or virtual filesystem switch is an abstract layer on top of a more concrete file system. The purpose of a VFS is to allow client applications to access different types of concrete file systems in a uniform way. A VFS can, for example, be used to access local and network storage devices transparently without the client application noticing the difference. It can be used to bridge the differences in Windows, classic Mac OS/macOS and Unix filesystems, so that applications can access files on local file systems of those types without having to know what type of file system they are accessing.
