A computer on which a hypervisor runs one or more virtual machines is called a host machine, and each virtual machine is called a guest machine. The hypervisor presents the guest operating systems with a virtual operating platform and manages the execution of the guest operating systems. Unlike an emulator, the guest executes most instructions ...
Time-synchronization capabilities (guest synchronizes with host machine's clock) Support for Unity, a feature that allows seamless integration of applications with the host desktop [126] by hiding the monitor of the Virtual Machine and drawing the windows of applications running in the virtual machine on the host. Unity support was added for ...
VMware Horizon provides virtual desktop and app capabilities to users utilizing VMware's virtualization technology. A desktop operating system - typically Microsoft Windows - runs within a virtual machine on a hypervisor. VMware Horizon product has a number of components which are required to provide the virtual desktops, including:
The QEMU maintainers merged support for providing SPICE remote desktop capabilities for all QEMU virtual machines in March 2010. The QEMU binary links to the spice-server library to provide this capability and implements the QXL paravirtualized framebuffer device to enable the guest OS to take advantage of the performance benefits the SPICE ...
Process virtual machines were a popular approach to implementing early microcomputer software, including Tiny BASIC and adventure games, from one-off implementations such as Pyramid 2000 to a general-purpose engine like Infocom's z-machine, which Graham Nelson argues is "possibly the most portable virtual machine ever created".

A virtual machine implements functionality of a (physical) computer with an operating system. The software or firmware that creates a virtual machine on the host hardware is called a hypervisor or virtual machine monitor. [2] Software executed on these virtual machines is separated from the underlying hardware resources.
[8] [9] For some guest operating systems, a "Guest Additions" package of device drivers and system applications is available, [10] [11] which typically improves performance, especially that of graphics, and allows changing the resolution of the guest OS automatically when the window of the virtual machine on the host OS is resized.
