Hyper-V on Windows: a guide to creating and configuring virtual machines. Automatic startup and shutdown of virtual machines on the Microsoft Hyper-V platform Installing hyper v server on Windows 7

Some time ago we wrote about autorun virtual machines VMware vSphere and Citrix XenServer, but Microsoft Hyper-V administrators also face this problem. Just like on the vSphere platform, Hyper-V has settings to control the behavior of virtual machines when the host server is turned on and off.

So, if you open the virtual machine settings in Hyper-V, you will see an item like Automatic Start Action, where the settings for the behavior of the VM when the host starts are actually set:

There are three options for how the machine behaves when starting the Hyper-V host:

• Nothing - By default, the virtual machine does not start when the host server starts.
• Automatically Start If It Was Running When The Service Stopped - This option is useful when testing various applications in the VM (which, for example, can reboot the host) and the presence of machines that do not always turn on, but as needed. If you select this item, the virtual machine will be launched only if it was running when the host was shut down or rebooted.
• Start This Virtual Machine Automatically - This option is best used for productive virtual machines. It will allow you to start the virtual machine when the host starts in any case. There is also an option to delay before starting the VM, which will allow you to configure the order in which dependent services are launched (for example, the controller Active Directory launch without delay, then the base Microsoft SQL, and after a while we launch the application server and web server). In addition, this option will prevent all machines from creating a load on the storage subsystem at the same time, distributing it over time.

In addition to autostart of virtual machines, you can also configure Automatic Stop Action- action performed when the Hyper-V host server is shut down. This is also in the properties of the virtual machine:

There are also 3 behavior options here:

• Save The Virtual Machine State- this option allows you to minimize the downtime of the virtual machine in the event of a host shutdown. If a scheduled shutdown occurs, the virtual machine's memory will be saved to disk, after which the machine will be suspended. When you turn on the virtual machine, its memory will be restored, and it will continue to function as if nothing had happened (though not in all cases). This saves the time required to load and initialize guest OS services. However, with a large number random access memory required by the VM, the time it takes to unload it to and from disk can also take a significant amount of time. This option is enabled by default.
• Turn Off The Virtual Machine- this option will “hard” shut down the virtual machine (analogous to a sudden power outage). In this case, nothing will be saved, plus there are no guarantees of data consistency inside the VM (and as a result, there are no guarantees that it will load at all). But this happens the fastest, so it is convenient when using a test environment, where data safety is not so important, and everything needs to be done quickly. In addition, such a shutdown is guaranteed to occur, unlike the next or previous points.
• Shutdown The Guest Operating System- in this case, a graceful shutdown procedure is initiated in the guest OS. The system state will also not be saved, but most likely the system state will be consistent, since read-write operations will be completed correctly. If this option is used, then you need to configure the boot order of systems accordingly in the previous paragraph (autostart), since it takes time to initialize the OS and services when starting virtual machines.

Here we must not forget that if you have selected the “Save The Virtual Machine State” option, then you will need significant disk space for the .BIN files in which the virtual machine memory is located (the sum of the VM memory with this setting).

Hello friends, in today’s article we will connect a Hyper-V virtual machine to our Windows 8 and install the Windows 7 and Windows 8 operating systems on it, and also answer all the questions asked by users. By the way, you can transfer your entire physical computer to Hyper-V! Several system administrators I know work only on Hyper-V and have even forgotten what a normal operating system is. At the very beginning we publish several of your letters.

Installing Hyper-V

If you have Windows 8 Pro or Windows 8 Enterprise (corporate) installed on your computer, then you can use the Hyper-V virtualization system or, in simple words, use the virtual machine built into the Windows 8 operating system. It is very easy to use and I have no doubt that you will understand it.

For Hyper-V to work, your processor must support virtualization technology. Before work, be sure to enable the following options in the computer BIOS:

"Intel Virtualization Technology" for Intel processors or "AMD Virtualization" for AMD processors.

I warn you that Hyper-V is primarily designed and intended for IT professionals and is used on servers.

When working in Hyper-V, you will not be able to use a flash drive, sound card, and WiFi, in this regard it is preferable to use VirtualBox. But I still think that those who read this article know why they need it.

For its operation, the Hyper-V virtual machine makes small requirements:

Windows 8 Pro must be 64 bit.

Availability of at least 4GB of RAM.

Hyper-V connection

Opening Control Panel

and choose Programs

Programs and components. Turn Windows features on or off

Find the Hyper-V partition and mark it with a checkmark and click OK.

There will be a short search for the required files and a reboot.

After the reboot, go to the Metro interface and left-click on the arrow, then select Hyper-V Manager,

The Hyper-V Setup Wizard appears. Click on the name of our computer, then Create And Virtual machine.

Hyper-V Settings

1) Getting started. This master will help you create a virtual machine, click Next.

2) Specify a location. We assign a name to the virtual machine in Latin, for example Windows 7. We indicate the location of the files of the Hyper-V virtual machine, since I don’t have space on drive C:, I will check the Save virtual machine in another location checkbox and click browse, then specify the drive D: and Next.

3) Specify the generation. I want to install Windows 7 so I will select Generation 1.

4) Allocate memory. My computer has 8GB of RAM, which means I can safely allocate 2GB of RAM for a virtual machine. Check the box “Use dynamic memory for this virtual machine” and Next.

5) Network setup. We skip this parameter (we’ll set up an Internet connection later) and click Next.

6) Connect the virtual hard disk. Mark the item Create a virtual hard disk. So in the second paragraph Specify location, we indicated the location of the virtual machine files on the D: drive, then by default the virtual machine will offer us to locate the virtual hard disk on the D:\Windows 7\Virtual Hard Disks\ drive.

Friends, the item Size 127 GB does not mean that 127 GB will immediately be “squeezed out” on your D: drive.

Note: A virtual hard disk can be created at the very beginning, that is, before you create a virtual machine, and in this case you can choose which virtual hard disk to create, for example:

Dynamic(grows in volume gradually, according to accumulated data, at first it takes up several megabytes).

Fixed size(immediately requires allocation for the required space; if you create a 120 GB disk, that means you must allocate exactly that much space to it).A fixed-size hard drive is considered to have higher performance.

More detailed information see the end of the article.

7) Installation parameters. Check the box Install the operating system later. Further.

8) Done

How to set up Internet in Hyper-V

Now let's set up the network. In the main Hyper-V window, click on the Virtual Switch Manager button.

In the window that appears, select what type of virtual switch you want to create. I will select the type - External network. WITH create a virtual switch.

Choose an arbitrary name for the virtual switch. Network wifi adapter on my computer from the manufacturer "Atheros", so I will choose this name. Apply.

Choose Options

A window will open, on the left side of which you can see two sections with different parameters; if you select the parameter you need with the left mouse, then on the right side of the window you can configure it.

Network adapter. In the right part of the window, select our Virtual Switch "Atheros", Apply And OK.

Installation on Hyper-V operating system

Now the actual question is how to install the operating system in a virtual machine. To install a Hyper-V virtual machine, you need to boot it from installation disk Windows 7 located in the drive or for these purposes you need to use an ISO image with Windows.

, then on the right side of the window using the buttons Up And Down We set the virtual machine boot to what we need:

CD- boot from installation disk or ISO image.

Choose Controller 1 IDE and click on the plus sign, then DVD drive if you want to boot the virtual machine from DVD drive check the box Physical CD drive DVD discs: Next, insert the Windows 7 installation disk into the drive.

Also, to boot a virtual machine and install an ISO image with Windows 7, you can use Windows 7, in this case you need to check the File image item and click the Browse button, in the explorer that opens you need to select the image with Windows 7 and click Open. Apply and OK.

Click Start and the virtual machine starts. Hyper-V is loading from the Windows 7 ISO image. Double-click with the left mouse on the thumbnail of the Hyper-V virtual machine window,

A window will open in which you and I will work. Press any key, otherwise boot from installation Windows disk 7 won't happen. At the top of the window there are virtual machine settings buttons.

The usual Windows 7 installer dialog box. Next, you can install the Windows 7 operating system on the virtual machine. The whole process is described in detail in our article.

So you and I connected a Hyper-V virtual machine to our operating system and installed Windows 8 on it, the Internet is present on the virtual machine. You can install Windows 8 on it in exactly the same way.

How to create a virtual hard disk in Hyper-V

Friends, a virtual hard disk in Hyper-V can be created not only during the process of creating a virtual machine.

In the main window of the virtual machine, select Create -> HDD

Selecting the disc format. You can choose a new hard drive format, but please note that it is not supported by earlier operating systems before Windows 8

Select the disk type. You can create a fixed partition disk, which is considered higher performance

We indicate the location of the virtual hard disk if you have little free space on the C: drive, then place the virtual hard disk on the D: drive. Click on the Browse button and select drive D:

Disk setup. If we create a non-dynamic extensible virtual disk, and the virtual disk is a fixed partition, which means we must specify the exact size of the disk; if we specify the size of 127 GB, then this is exactly how much our virtual disk will occupy on the D: drive. Make sure you have enough free space on your D: drive.

note per parameter Copy the contents of the specified physical disk, you can use it if you want to transfer your physical computer along with all the settings to a virtual machine!

The virtual hard disk has been created. When creating a new virtual machine in step Connect a virtual hard disk we can check the box Use an existing virtual hard disk, then click Browse and specify the location of the virtual disk -D:\New virtual HDD.vhdx

Blue screen when creatingvirtual switch V Hyper-V

Friends, several times I had to deal with the fact that in the new Windows 8.1 operating system in the Hyper-V virtual machine, when creating a virtual switch, the operating system went into blue screen with error:

The problem seems to be caused by the following file: fwpkclnt.sys UNEXPECTED_KERNEL_MODE_TRAP *** STOP: 0x0000007f.

I tried to solve the problem different ways: reinstalling the virtual machine, restoring system files, removing the antivirus and firewall, updating drivers for all computer components, including network card. Unfortunately, only changing the network adapter helped.

In the operating room Microsoft system Windows 8 introduced Hyper-V virtualization technology, previously available only in Microsoft server operating systems.

System requirements for running Hyper-V in Windows 8

1. OS

Hyper-V is only available on 64-bit Windows versions 8/8.1. Supported editions of Windows 8/8.1 Professional and Enterprise operating systems.

2. CPU

• 64-bit processor made by Intel or AMD
• Support for virtualization technologies (Intel VT-x or AMD-V), as well as Second Level Address Translation (SLAT) technology. Intel calls this technology Extended Page Tables (EPT), while AMD calls it Rapid Virtualization Indexing (RVI).

Before enabling the Hiper-V component, you must check whether all these technologies are enabled in the BIOS/UEFI. In some cases, you may need to update the BIOS to enable them.

You can check whether the processor supports these virtualization technologies on the intel manufacturer's website http://ark.intel.com/Products/VirtualizationTechnology or amd http://products.amd.com/pages/desktopcpuresult.aspx

You can also use the utility for Intel processors IntelProcessorIdentificationUtility.

1. Download the program from Intel downloadcenter.intel.com

2. Install and run the program.

3. Go to tab CPU technologies, to check whether the processor supports virtualization technologies.

Enabling the Hyper V component in MS Windows 8.1

1. To install, you need to open Control Panel -> Programs and components and select item Enable or disable featuresWindows.

This window can be called up by pressing Win + R (to open the window Execute) and input OptionalFeatures.

2. In the window that opens, find the Hyper-V item

In addition to the platform itself Hyper-V this includes tools for its management - graphic equipment Hyper-V Manager and module Hyper-V for PowerShell.

3. Check all checkboxes necessary components and press OK, after which you will need to restart your computer.

4. After the reboot, shortcuts to launch will appear in the Metro interface Hyper-V Manager And Connections to a Hyper-V virtual machine.

5. These shortcuts are also available in C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Hyper-V Management Tools

Installing a guest operating system in Hyper-V

1. Open Hyper-V Manager

2. In the main menu, select Actions -> Create -> Virtual Machine… Similar actions are available in the right panel Actions.

3.In the wizard dialog box that opens, click the button Further

The wizard is required to assist in the process of configuring a virtual machine. It collects information about the location of the virtual machine, its name, information about virtual network to connect a virtual machine, virtual parameters hard drive etc.

4. In the next dialog box, specify the name of the virtual machine, and if you need to store the virtual machine in a location that is different from the default one suggested when installing Hyper-V, you must specify a new location.

5. In the next step, you need to specify the generation of the virtual machine

The second generation of virtual machines appeared only in latest version Hyper-V has a number of features, some of them are listed below:

• Only the following operating systems can be used as a guest operating system in a second generation virtual machine:
  1. Windows Server 2012 and Windows Server 2012 R2;
  2. Windows 8 (64 bit) or Windows 8.1 (64 bit).
• no legacy devices such as floppy drives and COM ports
• There is no IDE controller, instead there is a SCSI controller with boot capability
• the standard BIOS is replaced by firmware based on the Unified Extensible Firmware Interface (UEFI).

6. In the next dialog box, you must specify the amount of RAM for the guest system.

RAM configuration greatly affects Hyper-V performance. The option of using dynamic memory is available. When using dynamic memory, virtual machines that require more memory are allocated memory resources to virtual machines that have lower memory requirements. For example, those that are idle.

7.In the next step, the virtual machine creation wizard will show the screen Network configuration.

You must specify the virtual switch to which the virtual machine will be connected. If there is no choice of network adapters in this window, you must create a virtual switch after configuring the virtual machine.

8. In the next step, when configuring a new virtual machine, you need to set the radio button in the item Create a new virtual disk. You can specify the name of the virtual hard disk, its location, and its size. If the virtual machine has already been created, you can select Use an existing virtual hard disk or Connect the virtual disk later.

9. In the dialog box Installation options you need to choose where the operating system will be installed from. It is necessary to select the radio button in the Image file (.iso) item and specify the path to the iso image of the operating system being installed.

If the operating system distribution is recorded on disk, you must select PhysicalCD orDVD. If you need to specify the path to ISO image operating system, you can select Install the operating system later.

10.Dialog window for the final configuration of the virtual machine. If you need to make changes to the configuration, you must click the button Back. After pressing the button Ready an entry for the new virtual machine will appear in Hyper-V Manager in the status Off.

Creating and configuring a virtual switchHyperV

11.In the menu Actions choose Virtual Switch Manager.

There are three types of virtual networks that you can connect to in Hyper-V: private, internal, and external virtual network

A private virtual network allows all virtual machines to communicate with each other. Private networks do not have a physical network adapter associated with them. On this network, virtual machines cannot communicate with the host operating system, and the host OS cannot communicate with virtual machines in the private virtual network.

An internal virtual network is similar to a private virtual network in that it allows all virtual machines to communicate with each other, but unlike a private network, virtual machines can also communicate with the host system.

An external network is used when it is necessary to provide a virtual machine with access to physical network. Essentially, a physical network adapter is associated with a virtual switch, and Hyper-V takes over when the virtual machine tries to access the network through that switch.

12. Select virtual network type External -> Create virtual switch

13. In the virtual switch properties window that opens, you must specify the switch name and connection type.

14.When creating an external network, you can allow shared access to the network adapter from the virtual switch and the host system; to do this, you need to check the checkbox Allow the managing operating system to share this network adapter.

15 . If the network uses logical subnetting, then for a virtual switch connected to an external network, you can allow the use of VLANs by checking the checkbox Allow VLAN identification for the host operating system and specify the VLAN ID.

16.Press Apply-> OK

17. On the panel Virtual machines Hyper-V manager, select the configured virtual machine and open the context menu with the right mouse button.

18.V context menu choose Options -> Network adapter

19. Specify the created virtual switch for the selected virtual machine

20. Click Apply-> OK

21.Start the installation of the guest operating system by clicking on the icon Start on the panel Actions(you can also start the virtual machine by selecting in the main menu Action-> Start or via the context menu).

Back in Windows 8, Hyper-V virtualization technology appeared, previously available only in Microsoft server operating systems. This solution looks better than the Windows Virtual PC virtual machine included in Windows 7. Today I will tell you how to create a virtual machine in Windows using Hyper-V, and also set up the Internet, local network and file sharing in it.

In addition to Coreinfo, you can use Intel's proprietary utility (AMD has a similar one).

You can also look at the virtualization technology support table on your processor manufacturer's website: Intel | AMD.

Enable Hyper-V

Hyper-V is an operating system component that is initially disabled. Advanced users can enable it with one PowerShell command:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

If you prefer a GUI, press Win + R, enter OptionalFeatures and press Enter.

In the window that opens, select the Hyper-V checkbox.

One way or another, the component will become available after a system reboot. Among the problems with installation in Windows 8 RP, a cyclic reboot due to the fault of the drivers has been noticed so far USB controller 3.0, which on some systems was solved by disabling USB 3.0 in the BIOS.

Creating and configuring a virtual machine

Press Win + R, enter virtmgmt.msc and press Enter to open Hyper-V Manager. From the menu Actions select Create – Virtual machine.

The virtual machine creation wizard is extremely simple, but I will note some points for those who like detailed instructions with pictures. I will skip the network setup step now, since I will analyze this issue in more detail.

The standard location for virtual machines is a folder ProgramData, but it can be changed.

If you already have a virtual disk in VHD format, you can connect it. By the way, I did just that, using the disk I created earlier for Virtual Box.

When you specify an existing VHD, the wizard removes the step where you specify the media for installing the system.

However, you can specify the path to the ISO later by opening the virtual machine settings in the main Hyper-V Manager window.

Starting a virtual machine and installing Windows on it

Everything here is also simple, but a little unusual for those who have not previously encountered Hyper-V.

In Hyper-V Manager:

• To start the virtual machine, click “Start”
• To interact with it, click “Connect” or double-click the machine’s thumbnail

When the Windows bootable ISO image is specified in the machine parameters, you will see the familiar Press any key to boot message on the screen... Then you can handle it yourself, but if you need step by step instructions for installation, they are on OSZone for Windows 7 and Windows 8.

If the operating system on the physical machine is newer than the one installed on the virtual one, it is recommended to update the integration components (thanks, Artem). To do this, connect to the virtual machine in the Hyper-V manager, press Ctrl + I and run setup.exe.

Setting up Internet access and local network

The instructions in this section are only necessary if you are unhappy with the Default Switch introduced in Windows 10 1709, which cannot be removed or renamed. When using Default Switch, if the host is connected to a VPN, the virtual machine also uses the VPN. This is one of the main differences from an external switch, the creation of which I will describe later.

On the menu Actions select Setting up virtual switches. A window will open in which you can create a switch of one of three types. To enable your virtual machine to access the Internet, create external switch.

Now you need to set the name of the switch and select the network adapter if you have more than one. At home I use wireless network, so I chose a Wi-Fi adapter.

All that remains is to indicate the created switch in the parameters network connection virtual machine.

Now in installed Windows you will have an Internet connection and the local network between physical and virtual machines.

In the picture above you see:

• on the left is the result of adding a virtual switch to Hyper-V on a physical machine, i.e. network bridge and virtual adapter
• on the right – Internet access and connection to the local network on the virtual machine

As you can see, setting up the Internet and local network is not so much complicated as it is unusual for users of Microsoft client operating systems.

Sharing files between physical and virtual machines

As you work with a virtual machine, you regularly need to copy files from a physical one to it, or vice versa. I will describe several ways to solve this problem.

Shared network folders

This method works in all editions of Windows 10. Since we have a local network at our disposal, we can use shared folders to share files. In fact, the instructions below boil down to the basics of creating shared folders.

Access from virtual machine to physical machine

A picture is worth a thousand words, as the Americans say.

The figure shows the virtual machine explorer (VIRTUAL-PC), from where the physical machine (VADIK-PC) is accessed. Once you enter your account credentials, access to your profile will be at your disposal.

You may want to create a shared folder located on a physical machine outside of your profile. To do this, it is enough to use standard means providing shared access, but I will explain this process using the example of access to an arbitrary folder of a virtual machine.

Access from physical machine to virtual machine

Let's say there is a folder in the root of the virtual machine disk Shared. Right click on it and select General access – Individual people(or Specific users in Windows 7).

Now you can open a shared folder over the network in Explorer, including by entering the address of the form in the address bar \\computer-name\folder-name.

Connecting to a remote desktop of a virtual work machine

In Hyper-V, files cannot be exchanged between a physical and virtual machine by copying and pasting. You can only paste text copied on a physical machine using the keyboard shortcut Ctrl + V. However, once the virtual machine is running, you can connect to it via RDP instead of opening it from Hyper-V Manager. This method works in Pro editions and higher.

Actions on a virtual machine

First, you need to enable remote desktop connections on the virtual machine in the system properties. Press Win + R and run:

RUNDLL32.EXE shell32.dll,Control_RunDLL sysdm.cpl,5

Then allow the connection as shown in the picture.

All that remains is to find out the IP address of the virtual machine with the command ipconfig

Actions on a physical machine

Press Win + R and enter mstsc and expand login options.

In the window that opens:

1. Enter the IP address of the virtual machine (required).
2. Enter the username you want to use account you will be logged in.
3. Enable login credentials to be remembered.
4. Save the connection settings.

You can also set the Display tab to a resolution lower than what is used on the physical machine.

Now you can exchange files between physical and virtual machines using the usual keyboard shortcuts Ctrl + C and Ctrl + V.

Finally, I would like to virtualize a few recommendations from Denis Diaghilev for working with Hyper-V.

Use RDP to connect to virtual machines.

This will not only allow you to share files between the physical and virtual machine by copying and pasting, but will also save system resources that vmconnect consumes when connecting to the virtual machine in Hyper-V Manager or from command line.

If you plan to regularly use RDP to connect to various virtual machines, pin the program to the taskbar. Then the list of cars will be saved in the transition list.

Be careful with your photos

With Hyper-V you can create snapshots of a virtual machine using differential disk technology. However, the logic of the images is almost the opposite of what a person who has never stepped on a rake would expect from it.

Alexander Kosivchenko (MVP for virtualization) described in detail, although somewhat chaotically, the principle of operation of Hyper-V snapshots on Habré.

Use virtual machine import if necessary

Import will be more interesting to IT specialists, but I happened to use this function by accident. After creating the virtual machine, I renamed the drive letter where it was stored, and then Hyper-V Manager lost it.

Looking around in the snap, I saw the import option and instantly restored the machine.

Moreover, I didn’t even suspect that the actions I performed became possible only due to the emergence of a new feature in Hyper-V :)

Hyper-V vs. VirtualBox

While understanding Hyper-V, I involuntarily compared Microsoft solution for a client operating system with Oracle VirtualBox.

From the point of view of typical tasks of home users (testing the system installation, familiarization with it, checking the operation of applications), these solutions are practically no different from each other. But VirtualBox can be used in Windows 10 Home editions, while Hyper-V is not available in them.

VirtualBox does not have such strict hardware requirements, and its graphics capabilities are even greater, since it supports 3D hardware acceleration (though I have never used it).

Concerning GUI, then this is purely a matter of taste. Probably, the hypervisor that came from server operating systems looks more ascetic, but the parameters and configuration of virtual machines are generally very similar.

The presence of Hyper-V in Windows will primarily please IT professionals accustomed to this technology. For home users, this is a good opportunity to take advantage of the system’s built-in tools and expand their horizons by becoming familiar with Microsoft server technologies.

Survey

I became acquainted with virtual machines in 2004, when I started doing Windows Auto Install. Since then they have become an integral part of my daily work, including testing system settings, programs, etc.

In comments Tell us what virtualization solution you use and for what purpose!

I would like to thank Denis Diaghilev for his assistance in preparing this material. One of the benefits of the MVP program is exposure to top Microsoft technology talent. This means that you can get competent advice on any issue privately;)

Denis also kindly offered his assistance in facilitating the discussion. Therefore, if you have any technical questions regarding this article, you can count on qualified answers.

I want to specifically emphasize that

Using graphical interfaces such as Hyper-V Manager or System Center Virtual Machine Manager (SCVMM) makes managing Hyper-V quick and easy. However, there are many situations in which you can perform operations much faster if you have the ability to use the command line or scripts. In this article, we'll look at Powershell's capabilities for managing Microsoft Hyper-V.

Installing Powershell

First, we need to install Powershell.

To install Powershell on Windows 2008, go to Server Manager, further in Features. Click Add Features. Check Windows Powershell and press Next.

After that click Install.

To launch Powershell go to Start -All Programs -Windows Powershell.

At this moment the long-awaited dark blue will open Windows window Powershell:

Now we need to download the Hyper-V Powershell library.

Download and install Hyper-V Powershell Library

The developer of the Powershell management library for Hyper-V 1397 is James O’Neill and his library is simply invaluable when you have to manage Hyper-V from the command line. Follow the link above and download the file Hyperv.zip. Unpack the archive into a directory, for example C:\temp.

Now launch PowerShell, go to the directory with the unpacked scripts, disable PowerShell security with the command:

Set-ExecutionPolicy unrestricted

. c:\temp\hyperv.ps1

After this you will receive a security warning and you must select “ R” to run the script. After this you should see the message “ VM Functions Loaded” and a list of loaded commands.

Administering Hyper-V using PowerShell

Along with the library there is a help file that describes more than 100 commands included in the library. And remember that each of these 100 commands has a large number of parameters. A review of all the commands and their parameters would not fit into a dozen similar articles, so we will look at the most basic commands and their application.

Let's look at the following 5 commands and how they are used:

Displays summary information about all guests virtual machines on your Hyper-V server.

Start-VM, Stop-VM, Suspend-VM, and Shutdown-VM- the purpose of these commands is quite obvious. The parameter specifies the name of the virtual machine.

The easiest way to create a new virtual machine

- a list of all virtual machines on the server and the amount of memory it consumes

The command shows all snapshots taken on your Hyper-V server. To manage snapshots, you can additionally use the commands Update-VMsnapshot, New-VMsnapshot, Apply-VMsnapshot, Get-VMsnapshotTree, and Choose-VMsnapshot.

Not a bad laptop site, I liked the Acers the most: reviews of Acer laptops, all models, low prices.
