Virtualization Infrastructure Driver (VID)—The VSD provides partition management services, virtual processor management services, and memory management services. VMBus—The VMBus is a channel-based communication mechanism. It enables interpartition communication and device enumeration. It does so by means of the Virtualization Infrastructure Driver (VID), which controls access to the hypervisor and allows the management of virtual processors and memory. For each child partition created, a Virtual Machine Worker Process (VMWP) is instantiated in the parent partition, which manages the child partitions by interacting with the. This blog is a technical resource for developers and network support engineers and managers as well as providing an insight into the development of our application launcher, network automation and network audit & documentation products. It says that the Hyper-v is not running and virtualization infrastructure driver (VID) is not running. So I did a fix and run “bcdedit /set hypervisorlaunchtype auto” as Administrator. But it did not fix the problem. So I tried going to BIOS and check if the Intel Virtualization is Enable. And yes it is enabled.

This topic describes the Hyper-V role in Windows Server, practical uses for the role, the most significant new or updated functionality in this version compared to previous versions of Hyper-V, hardware requirements, and a list of operating systems (known as guest operating systems) supported for use in a Hyper-V virtual machine.
If you're looking for details on newer versions of Hyper-V, see:
Note
Hyper-V in Windows and Windows Server can replace older hardware virtualization products from Microsoft, including Microsoft Virtual Server, Microsoft Virtual PC, and Windows Virtual PC.
Role and technology description
The Hyper-V role enables you to create and manage a virtualized computing environment by using virtualization technology that is built in to Windows Server. Installing the Hyper-V role installs the required components and optionally installs management tools. The required components include Windows hypervisor, Hyper-V Virtual Machine Management Service, the virtualization WMI provider, and other virtualization components such as the virtual machine bus (VMbus), virtualization service provider (VSP) and virtual infrastructure driver (VID).
The management tools for the Hyper-V role consist of:
GUI-based management tools: Hyper-V Manager, a Microsoft Management Console (MMC) snap-in, and Virtual Machine Connection, which provides access to the video output of a virtual machine so you can interact with the virtual machine.
Hyper-V-specific cmdlets for Windows PowerShell. Windows Server 2012 includes a Hyper-V module, which provides command-line access to all the functionality available in the GUI, as well functionality not available through the GUI. For more information about the Hyper-V module, see Hyper-V Module for Windows PowerShell.
If you use Server Manager to install the Hyper-V role, the management tools are included unless you specifically exclude them. If you use Windows PowerShell to install the Hyper-V role, the management tools are not included by default. To install the tools, use the parameter –IncludeManagementTools. For instructions about installing the Hyper-V role, see Install Hyper-V and create a virtual machine.
Note
Hyper-V management tools in Windows Server 2012 are designed to only manage the Windows Server 2012 version of Hyper-V. The tools cannot be used to manage earlier versions of Hyper-V.The Hyper-V management tools in Windows Server 2012 R2 can be used to manage Hyper-V on Windows Server 2012 R2 and Windows Server 2012.
The Hyper-V technology virtualizes hardware to provide an environment in which you can run multiple operating systems at the same time on one physical computer. Hyper-V enables you to create and manage virtual machines and their resources. Each virtual machine is an isolated, virtualized computer system that can run its own operating system. The operating system that runs within a virtual machine is called a guest operating system.
For more information about the architecture of Hyper-V, see the Windows Server 2012 Hyper-V Component Architecture Poster.
Practical applications
Hyper-V provides infrastructure so you can virtualize applications and workloads to support a variety of business goals aimed at improving efficiency and reducing costs, such as:
Establish or expand a private cloud environment. Hyper-V can help you move to or expand use of shared resources and adjust utilization as demand changes, to provide more flexible, on-demand IT services.
Increase hardware utilization. By consolidating servers and workloads onto fewer, more powerful physical computers, you can reduce consumption of resources such as power and physical space.
Improve business continuity. Hyper-V can help you minimize the impact of both scheduled and unscheduled downtime of your workloads.
Establish or expand a virtual desktop infrastructure (VDI). A centralized desktop strategy with VDI can help you increase business agility and data security, as well as simplify regulatory compliance and management of the desktop operating system and applications. Deploy Hyper-V and Remote Desktop Virtualization Host (RD Virtualization Host) on the same physical computer to make personal virtual desktops or virtual desktop pools available to your users.
Increase efficiency in development and test activities. You can use virtual machines to reproduce different computing environments without the need for acquiring or maintaining all the hardware you would otherwise need.

New and changed functionality
Hyper-V in Windows Server 2012 and Windows Server 2012 R2 includes improvements in many areas.
For information about changes in Hyper-V in Windows Server 2012, see What's New in Hyper-V for Windows Server 2012.
For information about changes in Hyper-V in Windows Server 2012 R2, see What’s New in Hyper-V for Windows Server 2012 R2.
Hardware requirements
Hyper-V requires a 64-bit processor that includes the following:
Hardware-assisted virtualization. This is available in processors that include a virtualization option—specifically processors with Intel Virtualization Technology (Intel VT) or AMD Virtualization (AMD-V) technology.
Hardware-enforced Data Execution Prevention (DEP) must be available and enabled. Specifically, you must enable Intel XD bit (execute disable bit) or AMD NX bit (no execute bit).
Important
The Hyper-V role is not supported on a Microsoft Azure virtual machine. For a list of supported server roles, see Microsoft server software support for Microsoft Azure Virtual Machines.
Software requirements (for supported guest operating systems)
Hyper-V includes a software package for supported guest operating systems that improves integration between the physical computer and the virtual machine. This package is referred to as integration services. In general, you install this package in the guest operating system as a separate procedure after you set up the operating system in the virtual machine. However, some operating systems have the integration systems built-in and do not require a separate installation. For instruction on installing integration services, see Install Hyper-V and create a virtual machine. For more information about the functionality included with integration services, see Integration Services.
The following topics list the operating systems supported in Windows Server 2012 and Windows Server 2012 R2 for use as guest operating systems in Hyper-V virtual machines, as well as provide information about integration services:
For supported Linux distributions as a guest operating systems on Hyper-V, see Linux and FreeBSD Virtual Machines on Hyper-V.

Memory handling by Informix
All memory used by the Informix Dynamic Server is shared among the pool of virtual processors. In this way, Informix Dynamic Server can be configured to automatically add more memory to its shared memory pool in order to process client requests expeditiously. Data from the read-only data dictionary (system catalog) and stored procedures are shared among users rather than copied, resulting in optimized memory utilization and fast execution of heavily used procedures. This feature can provide substantial benefit in many applications, particularly those accessing many tables with a large number of columns and/or many stored procedures. Informix Dynamic Server also allocates an area, called the thread stack, in the virtual portion of shared memory to store nonshared data for the functions that a thread executes. The thread's stack tracks the state of a user session and enables a virtual processor to protect a thread's nonshared data from being overwritten by other threads concurrently executing the same code. Informix Dynamic Server dynamically grows the stack for certain operations such as recursive stored procedures. Informix Dynamic Server's shared memory minimizes fragmentation so that memory utilization does not degrade over time. Beyond the initial allocation, shared memory segments are automatically added in large chunks as needed but can also be added by the administrator while the database is running. The memory management system will also attempt to automatically grow the memory segment when it runs out of memory. When a user session terminates, the memory it used is freed and reused by another session. Memory can be reclaimed by the operating system by freeing the memory allocated to the database. User threads can, therefore, easily migrate among the virtual processors, contributing to Informix Dynamic Server's scalability as the number of users increases.
