    However, there are a few emulator or VM apps that require that the android device to be rooted for the app to work, and there are others that do not require such. Some remote terminal access apps also have the ability to access Android's internally implemented Toybox, via device loopback support. Some VM/emulator apps have a fixed set of OS's ...

    The majority of limitations are seen in emulation-based apps rather than the platform virtualization based apps, as the emulation apps must utilize a compatibility layer. Thus for libraries and packages to work as expected like in a real OS, the compatibility layer must work properly and must be able to provide accurate information.

    For example, if a file server has a number of hard drives that are only partially filled, file-based virtualization can be used to store files on those drives, thereby increasing the utilization of the storage devices. File-based virtualization can be used to create a virtual file server (or virtual NAS device), which is a storage system that ...
