How to Manage Hyper-V VM Checkpoints with PowerShell

How to Manage Hyper-V VM Checkpoints with PowerShell

In this blog post we are going to have a look at how you can create, manage, apply, and remove VM Checkpoints in Hyper-V using PowerShell. Hyper-V virtual machine (VM) checkpoints are one of the great benefits of virtualization. Before Windows Server 2012 R2, they were known as virtual machine snapshots. VM Checkpoints in Hyper-V allow you to save the system state of a VM to a specific time and then revert back to that state if you need to. This is great if you are testing software and configuration changes, or if you have a demo environment, which you want to reset.

Hyper-V VM Checkpoint Types

Before we got on how you can manage Hyper-V VM Checkpoints with PowerShell, let me first explain the two different types. Since Windows Server 2016 and Windows 10, Hyper-V includes two types of checkpoints, Standard Checkpoints, and Production Checkpoints.

  • Standard Checkpoints: takes a snapshot of the virtual machine and virtual machine memory state at the time the checkpoint is initiated. A snapshot is not a full backup and can cause data consistency issues with systems that replicate data between different nodes such as Active Directory. Hyper-V only offered standard checkpoints (formerly called snapshots) prior to Windows 10.
  • Production Checkpoints: uses Volume Shadow Copy Service or File System Freeze on a Linux virtual machine to create a data-consistent backup of the virtual machine. No snapshot of the virtual machine memory state is taken.

You can set up these settings in Hyper-V Manager or in PowerShell.

Hyper-V VM Checkpoint Types

If you are using PowerShell to configure Checkpoints for virtual machines these commands may help you.

Configure and set VM for Standard Checkpoints

Set-VM -Name "Windows10" -CheckpointType Standard

Set VM to Production Checkpoints, if the production checkpoint fails a Standard Checkpoint is created

 Set-VM -Name "Windows10" -CheckpointType Production

Set VM to only use Production Checkpoints

 Set-VM -Name "Windows10" -CheckpointType ProductionOnly

Disable VM Checkpoints for the Hyper-V virtual machine

 Set-VM -Name "Windows10" -CheckpointType Disabled

Managing Hyper-V VM Checkpoints using PowerShell

Create VM Checkpoints

You can create a new VM Checkpoint with PowerShell, you can round the following command:

Checkpoint-VM -Name "Windows10"

You can find more on the cmdlet on Microsoft Docs.

You can list the VM Checkpoints of a Hyper-V VM:

Get-VMCheckpoint -VMName "Windows10"

Applying Hyper-V VM checkpoints using PowerShell

If you want to revert your virtual machine state to a previous point-in-time, you can apply an existing checkpoint, using the following PowerShell command.

Restore-VMCheckpoint -Name "checkpoint name" -VMName "Windows10" -Confirm:$false

You can find more information about the cmdlet here.

Renaming checkpoints

To rename a checkpoint you can use the following command

Rename-VMCheckpoint -VMName "Windows10" -Name "Checkpointname" -NewName "MyNewCheckpointName"

Deleting checkpoints

You can also delete or remove a Hyper-V VM checkpoint with the following PowerShell command. This will merge the .avhdx files in the background.

Remove-VMCheckpoint -VMName "Windows10" -Name "Checkpointname"

Conclusion

I hope this blog post gives you a great overview on how you can manage, apply, restore, and remove Hyper-V VM Checkpoints using PowerShell. You can learn more about Hyper-V virtual machine checkpoints on Microsoft Docs. If you have any questions, feel free to leave a comment.

Windows File Recovery Tool WinFR

Recover Files on Windows using the Windows File Recovery Tool

Did you accidentally delete an important file, wiping a hard drive or partition, or need to restore corrupted files and data? We all have been there, with the newly released Microsoft Windows File Recovery tool you can recover and restore files on Windows. In this blog post, I am going to show you how you can recover and restore files on Windows using the Windows File Recovery tool. You can also use this tool to recover files from external drives and SD cards.

Accidentally deleted an important file? Wiped clean your hard drive? Unsure of what to do with corrupted data? Windows File Recovery can help recover your personal data.

For photos, documents, videos and more, Windows File Recovery supports many file types to help ensure that your data is not permanently lost.

Recovering from a camera or SD card? Try Signature mode, which expands beyond NTFS recovery and caters to your storage device needs. Let this app be your first choice for helping to find what you need from your hard drive, SSD (*limited by TRIM), USB drive, or memory cards.

I also want to make clear that this is no replacement for a backup, like Windows File History, Azure Backup, or products from third-party vendors. This tool is more of an emergency utility, you can restore files that were not backed up.

Requirements

To use the Windows File Recovery Tool, you have a couple of requirements.

  • You will need to run Windows 10, version 2004 (Build 19041), or later.
  • You can download the Windows File Recovery Tool from the Microsoft Store.
  • The source and destination drives must be different. If you don’t have a second drive on your computer, you can use a USB drive as a target for the restore. If you are storing form an SD card or external drive, you can use the internal system drive (often the C: drive) as a target.
  • The tool supports different file systems such as NTFS, ReFS, FAT, and exFAT. If you are restoring files from a non-NTFS file system, you will need to run the commands in signature mode using the /x parameter.


Run Hyper-V on Windows 10 on ARM and the Surface Pro X

Run Hyper-V on Windows 10 on ARM and the Surface Pro X

Here is a quick blog post on how you can run Hyper-V virtual machines (VM) on Windows 10 on ARM and the Surface Pro X.

I am running the Surface Pro X as my daily driver for a couple of months. It is a fantastic device and combines a light designed and the Surface Pro form factor with a 13-inch screen. But the most significant difference to the other Surface devices like the Surface Pro 7, is that the Surface Pro X is running Windows 10 on ARM. It has a custom Microsoft SQ1 chip. This limits it to run native ARM64 or emulated 32-bit x86 applications, and it can’t run classic 64-bit x64 applications at the moment. Another limitation was that I wasn’t able to run Hyper-V virtual machines (VMs) on my Surface Pro X.

With the Windows 10 Insider Preview build 19559, you were able to install Hyper-V. However, you didn’t have a compatible image to run inside the virtual machine (VM). With the Windows 10 Insider Preview Build 19631, Microsoft is now also providing an ARM64 VHDX file, which you can download and run as a guest OS in Hyper-V.

How to enable Hyper-V on Windows 10 on ARM

You need a Windows 10 ARM-based PC with a Microsoft SQ1, Qualcomm Snapdragon 8cx, or Qualcomm Snapdragon 850 processor. To enable the Hyper-V feature on Windows 10 on ARM and the Surface Pro X, you will also need to have installed the Windows 10 Insider Preview build 19559 or higher and have Windows 10 Pro or Windows 10 Enterprise.

  1. Join the Windows Insider Program and update to the latest Windows 10 Insider Fast Ring build 19559 or newer
  2. Upgrade your Windows edition from Home to Windows 10 Pro or Windows 10 Enterprise
  3. Install the Hyper-V feature on Windows 10You can run the following PowerShell command to install the Hyper-V feature.
    Enable-WindowsOptionalFeature -Online -FeatureName:Microsoft-Hyper-V -All
  4. Download the Windows 10 on ARM VHDX file from here.
  5. After that, you can create a Hyper-V virtual machine (VM) with an existing VHDX file on your Surface Pro X.
  6. Visit Windows 10 on ARM developer center for more details and documentation.

Conclusion

I hope this gives an overview of how to run Hyper-V VMs on Windows 10 on ARM. This is still in preview, but if you are like me and want to give it a try, you can. Let me know if you have any questions.



Windows Terminal Color Schemes -Themes

My Windows Terminal Color Schemes

The Windows Terminal became generally available at the Microsoft Build 2020 virtual conference a couple of weeks ago. I already blogged about how you can customize your Windows Terminal settings and shared my settings.json file. Many people asked me about the different Windows Terminal Color Schemes I use. So I thought a blog post would be a good way of sharing my Windows Terminal Schemes.

Windows Terminal 1.0 was released on May 19, you can find more documentation here on Microsoft Docs.

I already shared a couple of blog posts on how you can customize your Windows Terminal experience:

HCSDiag.exe - Hyper-V Host Compute Service Diagnostics Tool

HCSDiag.exe – Hyper-V Host Compute Service Diagnostics Tool

As you know, Hyper-V is not just a server virtualization software anymore. Today, you can find Hyper-V technology across different operating systems, products, and services, like Windows Defender Application Guard, Windows Sandbox, Hyper-V Containers, or many more. Thanks to Ben Armstrong from the Hyper-V team, I found out that there is a tool in Windows to troubleshoot these Hyper-V containers called hcsdiag.exe or Hyper-V Host Compute Service Diagnostics Tool. The Hyper-V Host Compute Service Diagnostics Tool (HCSDiag.exe) is available in Windows 10 and Windows Server 2019 if you have the Hyper-V roles or virtualization features enabled, and can be helpful to troubleshoot Hyper-V containers, virtual machines (VMs), Windows Sandbox, Windows Defender Application Guard, Windows Subsystem for Linux 2 and more.

HCSDiag.exe - Hyper-V Host Compute Service Diagnostics Tool

HCSDiag.exe – Hyper-V Host Compute Service Diagnostics Tool

Let’s have a look at the HCSDiag.exe, which you can find in C:\Windows\System32. It provides you with a couple of different commands and options. However, keep in mind that not all features work with every type of container. Some features are limited to scenarios where the VM is being used under the same user context as the host, where it is all about protecting the host from the guest and not the guest from the host like in the server version of Hyper-V.

To install Hyper-V, check out the following posts:

HCSDiag.exe

hcsdiag <command> [options…]

  • list
    Lists running containers and VMs.
  • exec [-uvm] <id> <command line>
    Executes a process inside the container.
  • console [-uvm] <id> [command line]
    Launches an interactive console inside the container.
  • read [-uvm] <id> <container file> [host file]
    Reads a file from the container and outputs it to standard output or a file.
  • write [-uvm] <id> [host file] <container file>
    Writes from standard input or a host file to a file in the container.
  • kill <id>
    Terminates a running container.
  • share [-uvm] [-readonly] [-asuser] [-port <portnumber>] <id> <host folder> <container folder>
    Shares a host folder into the container.
  • vhd [-uvm] <id> <host vhdx file> <container folder>
    Shares a virtual hard disk file into the container.
  • crash <id>
    Forces a crash of the virtual machine hosting the container (only works for containers hosted in a virtual machine).

I will give you some examples of how you can use hcsdiag.exe to interact with some of the Hyper-V containers. Now again, this focuses mostly on technologies like Windows Sandbox, Docker Hyper-V Containers, WSL 2, and similar features.

You can find more documentation on Hyper-V on Windows Server or Hyper-V on Windows 10 on Microsoft Docs.

List all containers and Hyper-V VMs

With the hcsdiag list command, you can create a list of containers and Hyper-V virtual machines running on the host. Including Windows Sandbox, Windows Subsystem for Linux 2, and Application Guard.

hcsdiag.exe list

hcsdiag.exe list

Connect Console to Hyper-V containers and Windows Sandbox

You can also directly connect to the console of containers or the Windows Sandbox. Remember that it only works for Hyper-V containers where the guest is not protected from the host. Not for containers like Hyper-V VMs, where the guest is also protected from the host. If you need to remote into want console access or run commands against a Hyper-V VM from the host, check out PowerShell Direct for Windows VMs and hvc.exe for Linux VMs.

hcsdiag console connect

hcsdiag console connect

Here is an example where I am connected to a Windows Sandbox container using hcsdiag.exe.

hcsdiag Windows Sandbox

hcsdiag Windows Sandbox

But that also works with Dockers container (Hyper-V containers) running Windows and Linux.

hcsdiag Linux Container

hcsdiag Linux Container

HCSDiag console provides you with an interactive connection to interact with the container.

Additional HCSDiag.exe features and commands

The HCSDiag.exe also provides you with a couple of additional commands you can use. For example, the read command to read a file from the container and output it to the host or as a file to the host.

hcsdiag read

hcsdiag read

You can use the “share” command to share a host folder into the container or use “vhd” to mount a virtual disk file (VHD) file to a container. The hcsdiag kill command terminates a running container.

Conclusion

HCSDiag.exe – Hyper-V Host Compute Service Diagnostics Tool is excellent if you need to troubleshoot these Hyper-V containers, virtual machines (VMs), Windows Sandbox, Windows Defender Application Guard, Windows Subsystem for Linux 2 and more. If you have any questions, feel free to leave a comment.



How to Change the Windows Terminal Default Shell Profile

How to Change the Windows Terminal Default Shell Profile

The Windows Terminal is now generally available as version 1.0. I already shared a blog post on how to customize the Windows Terminal and shared my personal settings.json file with a lot of different examples, like the integration of PowerShell Remoting, SSH Remoting, changing the background image and much more. One question I got is, how to change the Windows Terminal default shell or default profile from PowerShell to the Windows Subsystem for Linux (WSL) or the command line (cmd).

By default, the Windows Terminal takes PowerShell 7 (if it is installed) as the primary shell when you open the Windows Terminal. However, if you want to change that you can simply configure the default shell in Windows Terminal, in the settings.json file. On the top, you can find the “defaultProfile” setting with a GUID

{
    "$schema": "https://aka.ms/terminal-profiles-schema",
    "defaultProfile": "{574e775e-4f2a-5b96-ac1e-a2962a402336}",
....
}

The GUID is the GUID of your profile. For example, if you want to change it to cmd, you can use the following GUID “0caa0dad-35be-5f56-a8ff-afceeeaa6101”.

I hope this blog post gives you a look on how to switch the default shell in Windows Terminal. I recommend that you check out my other blog post where I share even more details on how to customize the Windows Terminal. You can also read the full announcement blog for the version 1.0 here or check out the documentation on Microsoft Docs.
