To start using MSLab just download the latest version of the scripts from the Releases section of this repository or follow Dell GEOS hands-on-labs.

MSLab is a GitHub project that aims to provide virtual environments in Hyper-V, that can be built in a consistent way. It comes at no additional cost, it's free and available under the MIT License.
Unlike other solutions, MSLab focuses on simplicity (all actions can be done without typing complex scripts) and low profile (all disks are differencing, minimum requirements are 8GB RAM and 40GB free space). There is no special hardware requirement. MSLab can run on almost any machine that has SSD and decent amount of memory.
- Windows 10 Pro/Enterprise (as Hyper-V is required) or Windows Server 2016/2019
- 8GB RAM
- CPU with Virtualization support
- SSD
- 40GB free space
The main part of MSLab are the Scripts that will help you preparing lab files (Hydration Phase). This phase is the most time consuming (1-2hours), but needs to be done only once. It will create virtual hard disks from of provided ISO and will create Domain Controller. MSLab Deployment takes only few minutes as it will just import Domain Controller and will add other Virtual Machines as specified in LabConfig.ps1

In the past, this ZIP file was stored in the git repository, and recently we switched to using a native Releases feature of Github, where all releases are available at https://github.com/microsoft/MSLab/releases. Also, we have a static direct link to the latest MSLab release on http://aka.ms/mslab/download which is updated automatically when we create a new version.
This built ZIP file is more optimized, e. g. the file 0_Shared.ps1 is in-lined to the rest of the scripts to keep the number of MSLab files as low as possible. Compared to the git repository where I tend to split those scripts to multiple independent files for a better supportability on our side.
Over the time, we have developed multiple scenarios simulating Azure Stack HCI and even deep dives into other technologies such as Windows Admin Center, Certification Authority or Just Enough Administration. Scenarios can be reused for real environments. For example S2D Hyperconverged can be used to deploy real Azure Stack HCI clusters.
MSLab is ideal for prototyping. It will quickly spin Windows Server/Client environments that are connected to Internet and ready to be played with. If something goes wrong, there is nothing easier than just run Cleanup and then Deploy again
MSLab virtual machines are defined in LabConfig.ps1 as simple hash table. This way you can share your configurations and create consistent, complex environments. Labs are easy to distribute. Once you are done with Hydration Phase, you can just copy result folder to multiple computers and deliver entire classes.
Many times happened, that there was an issue that was hard to reproduce. And even if you could reproduce it, another person did not have the same environment, so even with the same steps, the issue might not occur again. MSLab changes this as all MSLab environments with the same LabConfig are the same. So only thing you need to share to other person to reproduce issue are steps and LabConfig.ps1.

MSLab scripts work also in PowerShell 7, if you want to test it just install latest version of PowerShell 7.
If you also would like to have context menu integration like this:
You can use this script to register PowerShell Core integration in Explorer.
# Set context menu option
$pwshPath = "c:\Program Files\PowerShell\7-preview\pwsh.exe"
if(-not (Get-PSDrive -PSProvider Registry | Where-Object Root -EQ "HKEY_CLASSES_ROOT")) {
New-PSDrive -PSProvider Registry -Root "HKEY_CLASSES_ROOT" -Name "HKCR"
}
New-Item -Path "HKCR:\Microsoft.PowerShellScript.1\Shell" -Name "1"
New-ItemProperty -Path "HKCR:\Microsoft.PowerShellScript.1\Shell\1" -PropertyType String -Name "MUIVerb" -Value "Run with PowerShell &Core"
New-ItemProperty -Path "HKCR:\Microsoft.PowerShellScript.1\Shell\1" -PropertyType String -Name "Icon" -Value $pwshPath
New-Item -Path "HKCR:\Microsoft.PowerShellScript.1\Shell\1" -Name "Command"
Set-ItemProperty -Path "HKCR:\Microsoft.PowerShellScript.1\Shell\1\Command" -Name "(Default)" -Value ('"{0}" "-Command" "if((Get-ExecutionPolicy ) -ne ''AllSigned'') {{ Set-ExecutionPolicy -Scope Process Bypass }}; & ''%1''"' -f $pwshPath)
If your environment enforces running signed PowerShell scripts, scripts in release ZIP archive (starting from September 2022) are now signed with a code signing certificate. Although the code signing certificate is trusted you might see this warning when running the MSLab scripts:
This is by design behavior of PowerShell runtime, as certificates for scripts are stored in separate certificate store (Cert:\CurrentUser\TrustedPublisher\) and explicit decision is required for each certificate.
Also please keep in mind that any change to LabConfig.ps1 file would then require to sign that file again as any change in LabConfig would invalidate initial signature.
To sign LabConfig.ps1 file you can use this snippet that would select first available Code Signing certificate on your computer:
# Get a Code signing certificate from store
$certificate = Get-ChildItem -Path Cert:\CurrentUser\My\ -CodeSigningCert | Select-Object -First 1
# Add signature to a LabConfig file
Set-AuthenticodeSignature -FilePath "LabConfig.ps1" -Certificate $certificate
There is en experimental support for building Linux parent images in MSLab. For building those images MSLab use Packer tool. Supported Packer templates are hosted in separate GitHub repository https://github.com/microsoft/MSLab-templates.
To build a Linux parent disk Linux = $true need to be added to the LabConfig.ps1 before running any MSLab scripts. When 1_Prereq.ps1 is ran MSLab would download Packer if not present on the machine yet, generates SSH key pair unique per a MSLab instance folder. This SSH key will be hardcoded in every parent disk built by that instance.
After prerequisites stage additional PowerShell script CreateLinuxParentDisk.ps1 will be ParentDisks folder. You can use that script to build a Linux parent disk in the similar way like the Windows images.
You can also use your own SSH key that can be shared by multiple MSLab instances by explicitely specifying a path to it using SshKeyPath option in LabConfig.ps1.
Deploy.ps1 script is using hv_socket to connect to a Linux instances and provision them online (similar to how PowerShell Direct work for Windows virtual machines). By default, Linux virtual machines would also be joined to MSLab Active Directory via sssd tool.
All the supported Linux distributions and their Packer templates are in the Microsoft/MSLab-templates repository. Should you run to any problem with specific distribution, please open an issue directly in that repository.
