The Microsoft's Hyper-V virtualization server is available in "Server" editions of Windows, but also as a feature in client versions of Windows.
Before you start the installation of Microsoft Hyper-V, verify that your computer meets the requirements for Hyper-V.
Important : Hyper-V requires :
To do this, run a command prompt and type :
At the end of the information displayed by this command you will find :
Hyper-V Requirements: VM Monitor Mode Extensions: Yes Virtualization Enabled In Firmware: Yes Second Level Address Translation: Yes Data Execution Prevention Available: Yes
If everything is "yes", it's good.
Open the control panel and go to : Programs -> Uninstall a program.
Then, click on "Turn Windows features on or off".
Check the "Hyper-V" box and click OK.
Windows prepares the required files.
Then, Windows will have to restart.
Click on: Restart now.
Your computer will restart several times and Windows will configure features (in this case : those related to Hyper-V in this case).
Once the installation and configuration is complete, you will arrive on the Windows 8 home screen.
If you go on the right, you will see that the "Hyper-V Manager" has appeared.
On Windows 10, you will see the Hyper-V Manager appear in the start menu.
On Windows 11, open the start menu, search for "Hyper-V" and launch the "Hyper-V Manager".
The Hyper-V Manager of Windows 8 is very similar to that of Windows Server 2012.
However, unlike the installation of the Hyper-V role in Windows Server 2012 where the wizard offers you directly to create your first virtual switch, this is not the case in Windows 8.
It will therefore be necessary to create it manually.
In Hyper-V Manager, select your Hyper-V server and click on "Virtual Switch Manager".
Then, select "External" and click "Create Virtual Switch".
Choose "External network" and select which physical network adapter your virtual machines will use to access the network.
If you only have one physical network card on your computer, you will also need to check the "Allow management operating system to share this network adapter" checkbox.
Finally, click OK.
Click Yes to save the changes.
For Windows 10, Hyper-V will obviously be different from that of Windows 8 since it will look like Hyper-V of Windows Server 2016 and not that of Windows Server 2012.
Since Windows 10, a default virtual switch will be automatically configured during Hyper-V installation.
Nevertheless, as you can see, this one is not modifiable (even if you create another one) and only allows the communication of the virtual machines between them. This means that your virtual machines will not have access to physical machines on the network or to the Internet.
To quickly resolve the problem, simply create a new virtual switch and select the "External network" connection type.
Finally, click OK or Apply to save the changes.
Note : to use it, simply go to the settings of your virtual machines.
If your computer meets the requirements for Hyper-V, you will be able to create and use virtual machines.
