if it runs on windows, it's a type 2 hypervisor. if hyper-v was type 1, it would replace windows rather than be a windows feature.
:A general-purpose emulator that supports a wide range of hardware for use on a multitude of platforms. Used to be a hypervisor by way of KQEMU but has been deprecated in favor of other systems like KVM (a kernel module for Linux and FreeBSD) and HAXM (which is developed by Intel). QEMU has been used to emulate several non-PC x86 machines like [[XQEMU]] for the [[Xbox emulators|Xbox]], and [[Orbital]] for the [[PlayStation 4 emulators|PlayStation 4]]. The non-specific application of QEMU allows emulators like XQEMU and Orbital to function as hypervisors without having to write custom-made drivers.
;Hyper-V:Microsoft's server-oriented hypervisor. Requires a Pro, Enterprise, or Education version of Windows 10.:;Virtual PC::Microsoft's original offering for consumers, originally made by Connectix as commercial software until Microsoft made it a free download in 2006. Support ended with the introduction of Hyper-V, but the last version can still be downloaded [https://www.microsoft.com/en-us/download/details.aspx?id=3702 here].
==Type 1 hypervisors==
* Xen (open-source hypervisor developed for the Linux kernel)
* UnRAID (commercial NAS distribution with an integrated hypervisor)
* Hyper-V (Microsoft's server-oriented hypervisor. Requires a Pro, Enterprise, or Education version of Windows 8, 8.1, or 10)
==Integrations==
Many type 2 hypervisors include some sort of additional software that can be installed in a guest. This software listens to the hypervisor and facilitates communication between the guest and host, allowing for features like automatic screen resizing (where the host measures the height and width of the window and sends an optimal size for the guest to resize the display to), clipboard sharing (where anything copied on the host can be pasted in the guest), shared folders (where a directory on the host can be made available for access from a guest using a built-in file server and a direct network connection to the guest), and mouse integration (where the hypervisor emulates an absolute pointing device like a drawing tablet to give the impression that moving the cursor in and out of the machine's display is seamless). Three hypervisors are known to have them;
