There are many apps in Android that can run or emulate other operating systems, via utilizing hardware support for platform virtualization technologies, or via terminal emulation. Some of these apps support having more than one emulation/virtual file system for different OS profiles, thus the ability to have or run multiple OS's.
Depending upon how the desktop virtualization app works, they use RDP or can use another protocol of their own. Most business oriented desktop virtualization apps require specific types of equipment or services in order for the app to fully function. For example, VMware Horizon Client requires specific VMware equipment for the app to work. [2]
The Quick Emulator (QEMU) [4] is a free and open-source emulator that uses dynamic binary translation to emulate a computer's processor; that is, it translates the emulated binary codes to an equivalent binary format which is executed by the machine.
Instruction set extensions that have been added to the x86 instruction set in order to support hardware virtualization.These extensions provide instructions for entering and leaving a virtualized execution context and for loading virtual-machine control structures (VMCSs), which hold the state of the guest and host, along with fields which control processor behavior within the virtual machine.
Windows 10 64-bit and higher. Support for 64-bit Windows was added with VirtualBox 1.5. Support for 32-bit Windows was removed in 6.0. Support for Windows 2000 was removed in version 1.6. [76] [77] Support for Windows XP was removed in version 5.0. [78] [79] Support for Windows Vista was removed in version 5.2. Support for Windows 7 (64-bit ...
Hyper-V is a native hypervisor developed by Microsoft; it can create virtual machines on x86-64 systems running Windows. [1] It is included in Pro and Enterprise editions of Windows NT (since Windows 8) as an optional feature to be manually enabled. [2]
This approach is described as full virtualization of the hardware, and can be implemented using a type 1 or type 2 hypervisor: a type 1 hypervisor runs directly on the hardware, and a type 2 hypervisor runs on another operating system, such as Linux or Windows. Each virtual machine can run any operating system supported by the underlying hardware.
Nested virtualization becomes more necessary as widespread operating systems gain built-in hypervisor functionality, which in a virtualized environment can be used only if the surrounding hypervisor supports nested virtualization; for example, Windows 7 is capable of running Windows XP applications inside a built-in virtual machine.
