What is Virtual Machine Server?
Virtual Machine Server or VM server hosts multiple virtual machines, which in turn runs various operating systems that acts as a fully fledged computing platform to run software applications and websites through emulation and virtualization technique. Software developers use VM servers for testing web application, software across different platforms. A VM server hosts multiple virtual machines at once so that multiple activities can be done simultaneously. It offers fully functional virtual environments, allowing users to deploy the different kind of operating systems and software on a supported virtual environment.
Virtual machine servers can be operated in two modes:
Paravirtual Mode: In this kind of mode, only some hardware devices are not completely emulated. However, for other essential devices, real hardware is used.
Full Virtual Mode: It enables the virtual machine server emulate all hardware devices, used by the VMs.
