Hyper- V - Wikipedia. Microsoft. Hyper- V, codenamed Viridian[1] and formerly known as Windows Server Virtualization, is a native hypervisor; it can create virtual machines on x. Windows.[2] Starting with Windows 8, Hyper- V superseded Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT.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 alongside Windows Server 2. Windows Server and some client operating systems since. Hyper- V is also available on the Xbox One, in which it would launch both Xbox OS and Windows 1. History[edit]A beta version of Hyper- V was shipped with certain x. Windows Server 2. The finalized version was released on June 2. Windows Update.[3] Hyper- V has since been released with every version of Windows Server.[4][5][6]Microsoft provides Hyper- V through two channels: Part of Windows: Hyper- V is an optional component of Windows Server 2. It is also available in x. SKUs of Pro and Enterprise editions of Windows 8, Windows 8. Windows 1. 0. Hyper- V Server: It is a freeware edition of Windows Server with limited functionality and Hyper- V component.[7]Hyper- V Server[edit]Hyper- V Server 2. October 1, 2. 00. It consists of Windows Server 2. Server Core and Hyper- V role; other Windows Server 2. Windows services.[8] Hyper- V Server 2. 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 2. R2 (an edition of Windows Server 2. R2) was made available in September 2. Windows Power. Shell v.

R2 is not fully supported. Architecture[edit]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. A hypervisor instance has to have at least one parent partition, running a supported version of Windows Server (2. The virtualization stack runs in the parent partition and has direct access to the hardware devices. The parent partition then creates the child partitions which host the guest OSs. A parent partition creates child partitions using the hypercall API, which is the application programming interface exposed by Hyper- V.[9]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 (Syn. IC). 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. Child partitions do not have direct access to hardware resources, but instead have a virtual view of the resources, in terms of virtual devices. Any request to the virtual devices is redirected via the VMBus to the devices in the parent partition, which will manage the requests. The VMBus is a logical channel which enables inter- partition communication. The response is also redirected via the VMBus. If the devices in the parent partition are also virtual devices, it will be redirected further until it reaches the parent partition, where it will gain access to the physical devices. Parent partitions run a Virtualization Service Provider (VSP), which connects to the VMBus and handles device access requests from child partitions. Child partition virtual devices internally run a Virtualization Service Client (VSC), which redirect the request to VSPs in the parent partition via the VMBus. This entire process is transparent to the guest OS. Virtual devices can also take advantage of a Windows Server Virtualization feature, named Enlightened I/O, for storage, networking and graphics subsystems, among others. Enlightened I/O is a specialized virtualization- aware implementation of high level communication protocols, like SCSI, that allows bypassing any device emulation layer and takes advantage of VMBus directly. This makes the communication more efficient, but requires the guest OS to support Enlightened I/O. ![]() I'm running the new Windows 7 RC x64. I would like to set up a couple of virtual servers running on the same box as my desktop OS. I know that I can do this with some. Currently only the following operating systems support Enlightened I/O, allowing them therefore to run faster as guest operating systems under Hyper- V than other operating systems that need to use slower emulated hardware: System requirements[edit]Host operating system. An x. 86- 6. 4 processor. Hardware- assisted virtualization support: This is available in processors that include a virtualization option; specifically, Intel VT or AMD Virtualization (AMD- V, formerly code- named "Pacifica"). An NX bit- compatible CPU must be available and Hardware Data Execution Prevention (DEP) must be enabled. Although this is not an official requirement, Windows Server 2. R2 and a CPU with second- level address translation support are recommended for workstations.[1. Second- level address translation is a mandatory requirement for Hyper- V in Windows 8.[1. Memory. Minimum 2 GB. Each virtual machine requires its own memory, and so realistically much more.)Minimum 4 GB if run on Windows 8. Windows Server 2. Standard (x. 64) Hyper- V full GUI or Core supports up to 3. GB of memory for running VMs, plus 1 GB for the Hyper- V parent OS.[1. Maximum total memory per system for Windows Server 2. R2 hosts: 3. 2 GB (Standard) or 2 TB (Enterprise, Datacenter).[1. Maximum total memory per system for Windows Server 2. TB. Guest operating systems. Hyper- V in Windows Server 2. R2 supports virtual machines with up to 4 processors each (1, 2, or 4 processors depending on guest OS- see below)Hyper- V in Windows Server 2. Hyper- V in Windows Server 2. R2 supports up to 3. VMs per system[1. Hyper- V in Windows Server 2. Hyper- V in Windows Server 2. Hyper- V supports both 3. VMs. Microsoft Hyper- V Server[edit]Stand- alone Hyper- V Server variant does not require an existing of Windows Server 2. Windows Server 2. R2. The standalone installation is called Microsoft Hyper- V Server for the non- R2 version and Microsoft Hyper- V Server 2. R2. Microsoft Hyper- V Server is built with components of Windows and has a Windows Server Core user experience. None of the other roles of Windows Server are available in Microsoft Hyper- V Server. This version supports up to 6. VMs per system.[1. System requirements of Microsoft Hyper- V Server are the same for supported guest operating systems and processor, but differ in the following: [1. RAM: Minimum: 1 GB RAM; Recommended: 2 GB RAM or greater; Maximum 1 TB. Available disk space: Minimum: 8 GB; Recommended: 2. GB or greater. Hyper- V Server 2. R2 has the same capabilities as the standard Hyper- V role in Windows Server 2. R2 and supports 1. VMs.[2. 0]Supported guests[edit]Windows Server 2.

Sphere 5, one of the most sought out feature from VMware is the ability to run nested 6. Hyper- V guest virtual machines in a virtual ESXi instance. Previous to this, only 3. VT- x/AMD- V Hardware Virtualization CPU instructions could not be virtualized and presented to the virtual ESX(i) guest. This feature is quite useful for home and lab setups in testing new features or studying for VMware certifications and running multiple v. ESX(i) instances. You will still be required to have a 6. CPU and you will need to be running ESXi 5. ESX(i) 4. x or older. The above diagram depicts the various levels of inception where p. ESXi is your physical ESXi 5. We then create a v. ESXi 5. 0 host which will contain the necessary Hardware Virtualization CPU instructions to support a 6. OS which I've created as another ESXi host called vv. ESXi. Note: You will not be able to run a 4th level nested 6. VM (I have tried by further passing the HV instructions in the nested guest) and it will just boot up and spin your CPUs for hours. This feature by default is disabled in ESXi 5. HV (Hardware Virtualization) you will need to add the following string vhv. TRUE" to /etc/vmware/config of your Physical ESXi 5. Once the configuration change has been made, the feature goes into effect right away. A reboot of the system is not necessary. To verify, you should now be able to power on a 6. OS and see that the HV instructions bits are being passed into the guest. OS which will then allow you to run a nested 6. OS. You can also verify by looking in the vmware. Control. vhv" and if you see the following message, then Virtualized HV is not enabled. In the past to run a virtual ESX(i) instance, a few advanced . With ESXi 5. 0, if you are using virtual hardware version 8, then you do not need to make any additional changes. If you are using hardware version 4 or 7, then you will need to add a few changes to the VM's configuration file. Creating v. ESXi 5. Instance using Hardware Version 8: 1. To create a virtual ESXi 5. RHEL5/6 6. 4bit VM using the v. Sphere Client. 2. Once the VM has been created, edit the settings of the VM and change over to the "Options" and now have the ability to select a new guest. OS type: VMware ESXi 5. VMware ESXi 4. x under the "Other" section. Note: I'm not sure why these two additional guest. OS type is not available from the default creation menu, but are available after the initial VM shell is created. You are now ready to install ESXi 5. ESXi host and then you can create and power on nested 6. OS within that v. ESXi instance as denoted from the picture below. Creating v. ESXi 5. Instance using Hardware Version 4/7: 1. To create a virtual ESXi 5. RHEL5/6 6. 4bit VM using the v. Sphere Client. 2. Now you will need to add the following advanced . Sphere Client and/or editing the . Next you will need to add some cpuid bits, depending if you are running an Intel or AMD CPU, the respective entries are required: Intel Hosts: cpuid. AMD Hosts: cpuid. You are now ready to install ESXi 5. ESXi host and then you can create and power on nested 6. OS within that v. ESXi instance. By using a VM that is hardware version 8, you can easily automate the creation of v. ESXi 5. 0 instance by changing the guest. OS string in the . Intel or AMD system are automatically configured. For proper networking connectivity, also ensure that either your standard v. Switch or Distributed Virtual Switch has both promiscuous mode and forged transmit enabled either globally on the portgroup or distributed portgroup your nested ESXi hosts are connected to. Creating a v. Hyper- V Instance on physical ESXi 5. To create a virtual Hyper- V instance, start off by creating a Windows 2. Server R2 6. 4bit VM using the v. Sphere Client. 2. If you are using Hardware Version 7, you will need to follow the instructions in "Creating v. ESXi 5. 0 Instance using Hardware Version 4/7" to add the additional parameters to the VM. If you are using Hardware Version 8, you just need to change the guest. OS type to VMware ESXi 5. You need to add one additional . OS (Hyper- V) that it is not running as a virtual guest which in fact it really is. The parameter is hypervisor. FALSE4. You are now ready to install Hyper- V in a virtual machine and you can also spin up nested 6. OSes in this virtual Hyper- V instance. As you can see, now you can even run Hyper- Crap, err I mean Hyper- V as a virtualized guest under ESXi 5. I did not get a chance to try out Xen, but I'm sure with the ability to virtualize the Hardware Virtualization instructions, you should be able to run other types of hypervisors for testing purposes. This is a really awesome feature but note that this is not officially supported by VMware, use at your own risk.
