Hyper-V is Microsoft's hardware virtualization product. It lets you create and run a software version of a computer, called a virtual machine. Each virtual machine acts like a complete computer, running an operating system and programs. When you need computing resources, virtual machines give you more flexibility, help save time and money, and are a more efficient way to use hardware than just running one operating system on physical hardware.
Hyper-V runs each virtual machine in its own isolated space, which means you can run more than one virtual machine on the same hardware at the same time. You might want to do this to avoid problems such as a crash affecting the other workloads, or to give different people, groups or services access to different systems.
Establish or expand a private cloud environment. Provide more flexible, on-demand IT services by moving to or expanding your use of shared resources and adjust utilization as demand changes.
Establish or expand a virtual desktop infrastructure (VDI). Use a centralized desktop strategy with VDI can help you increase business agility and data security, as well as simplify regulatory compliance and manage desktop operating systems and applications. Deploy Hyper-V and Remote Desktop Virtualization Host (RD Virtualization Host) on the same server to make personal virtual desktops or virtual desktop pools available to your users.
Hyper-V in Windows and Windows Server replaces older hardware virtualization products, such as Microsoft Virtual PC, Microsoft Virtual Server, and Windows Virtual PC. Hyper-V offers networking, performance, storage and security features not available in these older products.
Hyper-V and most third-party virtualization applications that require the same processor features aren't compatible. That's because the processor features, known as hardware virtualization extensions, are designed to not be shared. For details, see Virtualization applications do not work together with Hyper-V, Device Guard, and Credential Guard.
Computing environment - A Hyper-V virtual machine includes the same basic parts as a physical computer, such as memory, processor, storage, and networking. All these parts have features and options that you can configure different ways to meet different needs. Storage and networking can each be considered categories of their own, because of the many ways you can configure them.
Disaster recovery and backup - For disaster recovery, Hyper-V Replica creates copies of virtual machines, intended to be stored in another physical location, so you can restore the virtual machine from the copy. For backup, Hyper-V offers two types. One uses saved states and the other uses Volume Shadow Copy Service (VSS) so you can make application-consistent backups for programs that support VSS.
Optimization - Each supported guest operating system has a customized set of services and drivers, called integration services, that make it easier to use the operating system in a Hyper-V virtual machine.
Remote connectivity - Hyper-V includes Virtual Machine Connection, a remote connection tool for use with both Windows and Linux. Unlike Remote Desktop, this tool gives you console access, so you can see what's happening in the guest even when the operating system isn't booted yet.
For a summary of the features introduced in this version, see What's new in Hyper-V on Windows Server. Some features or parts have a limit to how many can be configured. For details, see Plan for Hyper-V scalability in Windows Server 2016.
Hyper-V is available in Windows Server and Windows, as a server role available for x64 versions of Windows Server. For server instructions, see Install the Hyper-V role on Windows Server. On Windows, it's available as feature in some 64-bit versions of Windows. It's also available as a downloadable, standalone server product, Microsoft Hyper-V Server.
Many operating systems will run on virtual machines. In general, an operating system that uses an x86 architecture will run on a Hyper-V virtual machine. Not all operating systems that can be run are tested and supported by Microsoft, however. For lists of what's supported, see:
Hyper-V is a hypervisor-based virtualization technology. Hyper-V uses the Windows hypervisor, which requires a physical processor with specific features. For hardware details, see System requirements for Hyper-V on Windows Server.
In most cases, the hypervisor manages the interactions between the hardware and the virtual machines. This hypervisor-controlled access to the hardware gives virtual machines the isolated environment in which they run. In some configurations, a virtual machine or the operating system running in the virtual machine has direct access to graphics, networking, or storage hardware.
Hyper-V has required parts that work together so you can create and run virtual machines. Together, these parts are called the virtualization platform. They're installed as a set when you install the Hyper-V role. The required parts include Windows hypervisor, Hyper-V Virtual Machine Management Service, the virtualization WMI provider, the virtual machine bus (VMbus), virtualization service provider (VSP) and virtual infrastructure driver (VID).
Hyper-V also has tools for management and connectivity. You can install these on the same computer that Hyper-V role is installed on, and on computers without the Hyper-V role installed. These tools are:
Another question from the Alteryx novice. One of the workflow outputs is the Tableau Hyper. When run first time the hyper file was created successfully. On consecutive workflow run hyper output errored out. How do I get the hyper over-written? Or maybe there is a better method to feed the output to Tableau?

Microsoft Hyper-V, codenamed Viridian,[1] and briefly known before its release as Windows Server Virtualization, is a native hypervisor; it can create virtual machines on x86-64 systems running Windows.[2] Starting with Windows 8, Hyper-V superseded Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V was first released with Windows Server 2008, and has been available without additional charge since Windows Server 2012 and Windows 8. A standalone Windows Hyper-V Server is free, but has a command-line interface only. The last version of free Hyper-V Server is Hyper-V Server 2019, which is based on Windows Server 2019.
A beta version of Hyper-V was shipped with certain x86-64 editions of Windows Server 2008. The finalized version was released on June 26, 2008 and was delivered through Windows Update.[3] Hyper-V has since been released with every version of Windows Server.[4][5][6]
Hyper-V Server 2008 was released on October 1, 2008. It consists of Windows Server 2008 Server Core and Hyper-V role; other Windows Server 2008 roles are disabled, and there are limited Windows services.[8] Hyper-V Server 2008 is limited to a command-line interface used to configure the host OS, physical hardware, and software. A menu driven CLI interface and some freely downloadable script files simplify configuration. In addition, Hyper-V Server supports remote access via Remote Desktop Connection. However, administration and configuration of the host OS and the guest virtual machines is generally done over the network, using either Microsoft Management Consoles on another Windows computer or System Center Virtual Machine Manager. This allows much easier "point and click" configuration, and monitoring of the Hyper-V Server.
Hyper-V Server 2008 R2 (an edition of Windows Server 2008 R2) was made available in September 2009 and includes Windows PowerShell v2 for greater CLI control. Remote access to Hyper-V Server requires CLI configuration of network interfaces and Windows Firewall. Also using a Windows Vista PC to administer Hyper-V Server 2008 R2 is not fully supported.
Microsoft ended mainstream support of the free version of Hyper-V Server 2019 on January 9, 2024 and extended support will end on January 9, 2029.[9] Hyper-V Server 2019 will be the last version of the free, standalone product. Hyper-V is still available as a role in Windows Server 2022 and will be supported as long as that operating system is, currently scheduled for end of extended support on October 14, 2031.[10]
Hyper-V implements isolation of virtual machines in terms of a partition. A partition is a logical unit of isolation, supported by the hypervisor, in which each guest operating system executes. There must be at least one parent partition in a hypervisor instance, running a supported version of Windows. The parent partition creates child partitions which host the guest OSs. The Virtualization Service Provider and Virtual Machine Management Service runs in the parent partition and provide support for child partition. A parent partition creates child partitions using the hypercall API, which is the application programming interface exposed by Hyper-V.[11]
A child partition does not have access to the physical processor, nor does it handle its real interrupts. Instead, it has a virtual view of the processor and runs in Guest Virtual Address, which, depending on the configuration of the hypervisor, might not necessarily be the entire virtual address space. Depending on VM configuration, Hyper-V may expose only a subset of the processors to each partition. The hypervisor handles the interrupts to the processor, and redirects them to the respective partition using a logical Synthetic Interrupt Controller (SynIC). Hyper-V can hardware accelerate the address translation of Guest Virtual Address-spaces by using second level address translation provided by the CPU, referred to as EPT on Intel and RVI (formerly NPT) on AMD.
