What is virtualization? Simply put, it’s the process of creating a virtual, rather than physical, version of something. Virtualization can apply to computers, operating systems, storage devices, applications, or networks. However, server virtualization is at the heart of it.
IT organizations are challenged by the limitations of today’s x86 servers, which are designed to run just one operating system and application at a time. As a result, even small data centers have to deploy many servers, each operating at just 5 to 15 percent of capacity—highly inefficient by any standard.
Virtualization uses software to simulate the existence of hardware and create a virtual computer system. Doing this allows businesses to run more than one virtual system – and multiple operating systems and applications -- on a single server. This can provide economies of scale and greater efficiency.
The Hyper-V server role in Windows Server lets you create a virtualized server computing environment where you can create and manage virtual machines. You can run multiple operating systems on one physical computer and isolate the operating systems from each other. With this technology, you can improve the efficiency of your computing resources and free up your hardware resources.
Hyper-V on Vmware workstation issue :
According to this VMware document, it's possible to run a VM within a VM with Player 7: "Virtualized HV is fully supported for virtual hardware version 9 or later VMs on hosts that support Intel VT-x and EPT or AMD-V and RVI. To enable virtualized HV, select VM->Settings and navigate to the processor settings screen. Check the box next to "Virtualize Intel VT-x/EPT or AMD-V/RVI."
How to fix that ? :
Well,to solve this issue just follow the few steps bellow :
1- Go to your vmware folder (where vmware store Virtual Machines) :
2- Chose your VM folder and open it :
3- Now locate a file called "YourVMname.vmx" and open it with your text editor :
4- Add these lines just at the end of the file :
5- Save your work and close the file
hypervisor.cpuid.v0 = "FALSE"
mce.enable = "TRUE"vhu.enable = "TRUE"
6- Now open Vmware Workstation and go to your VM settings :
7- Chose Processors ->Virtualization engine and check the box next to :
- Virtualize CPU performance counters
