Migrate Hyper-V VMs to Azure using Azure Migrate

Assess and Migrate Hyper-V VMs with Azure Migrate

Today, the Azure Migrate team launched an update to the Azure Migrate service, which can help you discover, assess, and migrate applications, infrastructure, and data from your on-prem environment to Microsoft Azure. This is excellent timing since we all know that Windows Server 2008 and Windows Server 2008 R2 are soon out of support and you get free extended security updates if you migrate your VMs to Azure. With Azure Migrate, you can now centrally track the progress of your migration journey across multiple thrid-party and Microsoft tools. In addition, Azure Migrate can now assess and migrate your Hyper-V virtual machines (VMs).

With the latest release of Azure Migrate you can now:

  • Extensible approach with choice across Microsoft and popular ISV assessment and migration tools
  • Integrated experience for discovery, assessment, and migration with end-to-end progress tracking for servers and databases
  • Server Assessment and Server Migration for large-scale VMware, Hyper-V, and physical server migrations
  • Database Assessment and Database Migration across various database targets including Azure SQL Database and Managed Instance

You can find more about the Azure Migrate capabilities on Microsoft Docs. For more information on Azure Migration, check out my blog post about Azure Migration on the Nigel Frank International blog. In this post, I am going to show you how you can step-by-step assess and migrate Hyper-V VMs to Azure using Azure Migrate.

Preparation

First, you need to prepare your Azure to set the right permissions and prepare the on-premises Hyper-V hosts and VMs for server assessment and migration. You can find more about the details for permissions and host preparations on Microsoft Docs.

Next, you will need to create a new Migration project for servers. Click on Asses and migrate servers.

Now you will need to add the tools you want to use for the assessment as well as for the migration, click on “add tools”.

Getting started

Getting started

You will need to create a new Azure Migrate project. Enter the details for your subscription, resource group, and a name for the project. You will also need to choose a region where your project is going to be deployed. No worries, this will only store the assessment data, you can still select another region for the migration.



Copy files to Azure VM using PowerShell Remoting

Copy Files to Azure VM using PowerShell Remoting

There are a couple of different cases you want to copy files to Azure virtual machines. To copy files to Azure VM, you can use PowerShell Remoting. This works with Windows and Linux virtual machines using Windows PowerShell 5.1 (Windows only) or PowerShell 6 (Windows and Linux). Check out my blog post at the ITOpsTalk.com about copying files from Windows to Linux using PowerShell Remoting.

Prepare your client machine

Prepare the client machine to create PowerShell Remote connections to a specific remote VM.

Set-Item WSMan:localhost\client\trustedhosts -value "AZUREVMIP"

You can also enable remoting to all machines by using an asterisk.

Set-Item WSMan:localhost\client\trustedhosts -value *

Copy Files to Windows Server Azure VM

If you want to copy files to an Azure VM running Windows Server, you have two options. If you are copying files from Windows to Windows, you can use Windows PowerShell Remoting; if you are copying files from Linux or macOS to Windows, you can use the cross-platform PowerShell 6 and PowerShell Remoting over SSH.

Using Windows PowerShell Remoting

To copy files from a Windows machine to a Windows Server running in Azure, you can use Windows PowerShell Remoting.

Prepare the host (Azure VM) to receive Windows PowerShell remote commands. The Enable-PSRemoting cmdlet configures the computer to receive Windows PowerShell remote commands that are sent by using the WS-Management technology.

Enable-PSRemoting -Force

Now you can create a new PowerShell Remoting session to the Azure VM.

$cred = Get-Credential
 
$s = New-PSSession -ComputerName "AZUREVMIPORNAME" -Credential $cred

After the session was successfully created, you can use the copy-item cmdlet with the -toSession parameter.

Copy-Item .\windows.txt C:\ -ToSession $s

Some important notes

  • You need to configure the Network Security Group for the Azure VM to allow port 5985 (HTTP) or 5986 (HTTPS)
  • You can use PowerShell Remoting over Public Internet or Private connectivity (VPN or Express Route). If you are using the Public Internet, I highly recommend that you use https. I also recommend that you use Just-in-time virtual machine access in Azure Security for public exposed ports.

Using PowerShell Core 6 PowerShell Remoting over SSH

If you are running PowerShell Core 6, you can use PowerShell Remoting over SSH. This gives you a simple connection and cross-platform support. First, you will need to install PowerShell 6. After that, you will need to configure and setup PowerShell SSH Remoting together with OpenSSH. You can follow my blog post to do this here: Setup PowerShell SSH Remoting in PowerShell 6

Now you can create a new PowerShell Remoting session to the Azure VM.

$s = New-PSSession -HostName "AZUREVMIPORNAME" -UserName

After the session was successfully created, you can use the copy-item cmdlet with the -toSession parameter.

Copy-Item .\windows.txt C:\ -ToSession $s

Some important notes

  • You need to configure the Network Security Group for the Azure VM to allow port 22 (SSH)
  • You can use PowerShell Remoting over Public Internet or Private connectivity (VPN or Express Route). Exposing the SSH port to the public internet maybe is not secure. If you still need to use a public SSH connection, I recommend that you use Just-in-time virtual machine access in Azure Security.

Copy Files to Linux Azure VM

Copy File Windows to Linux using PowerShell Remoting

If you want to copy files to a Linux VM running in Azure, you can make use of the cross-platform PowerShell capabilities of PowerShell 6, using PowerShell Remoting over SSH. As for the Windows virtual machines, you will need to install PowerShell 6. Next, you will need to configure and setup PowerShell SSH Remoting together with OpenSSH. You can follow my blog post to do this here: Setup PowerShell SSH Remoting in PowerShell 6

After installing and configuring PowerShell Remoting over SSH, you can create a new PowerShell Remoting session to the Azure VM.

$s = New-PSSession -HostName "AZUREVMIPORNAME" -UserName

After you successfully connected to your Azure VM, you can use the copy-item cmdlet with the -toSession parameter.

Copy-Item .\windows.txt /home/thomas -ToSession $s

I hope this gives you an overview about how you can copy files to Azure VMs using PowerShell Remoting. If you have any questions, let me know in the comments.

Ubuntu VM on Windows 10

How to create an Ubuntu VM on Windows 10

Windows 10 is not just a modern desktop operating system, and it also has some great IT Pro and Developer related features build in. One of them is client Hyper-V. This is the same hypervisor which powers virtualization in Windows Server and the Microsoft Azure datacenters. With Hyper-V, you can create virtual machines running on Windows 10, without the need for third-party software. You can not just run Windows virtual machines, and you can also run Linux virtual machines. In this blog post, I am going to show you how you can create an Ubuntu VM on Windows 10 using Hyper-V.

If you want to know more about Hyper-V on Windows 10, check out the Microsoft Docs.

Install Hyper-V

First, you will need to install Hyper-V on your Windows 10 computer. Hyper-V on Windows 10 has the following requirements:

  • Windows 10 Enterprise, Professional, or Education (Home does not have the Hyper-V feature included)
  • 64-bit Processor with Second Level Address Translation (SLAT)
  • CPU support for VM Monitor Mode Extension (VT-c on Intel CPU’s)
  • Minimum of 4 GB memory

The easiest way to enable Hyper-V on Windows 10 is to run the following PowerShell command as an administrator:

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

After you have installed Hyper-V, you need to restart your computer.

Create an Ubuntu virtual machine on Windows 10

To create an Ubuntu virtual machine on Windows 10 Hyper-V, you could download the Ubuntu ISO file and install it like any operating system. However, there is a much easier way, using the Hyper-V Quick Create feature. In the Hyper-V VM Gallery, you will find not just two Windows 10 virtual machines; you will also currently find Ubuntu 18.04 LTS and Ubuntu 19.04. These are prepared Hyper-V virtual machines images, ready for you to download and install.

Ubuntu Hyper-V VM Images

Select the Ubuntu version you want to install and click on Create Virtual Machine. This will start downloading the virtual machine image.

Downloading Ubuntu Hyper-V VM Image

After the image is downloaded, you can either connect to the virtual machine and start it, or you can first modify the virtual machine settings.

Ubuntu 18.04 LTS Hyper-V VM

Optional: If you click on Edit settings, you will be able to configure the virtual machine hardware settings like vCPU or vRAM. You can also enable Secure Boot. If you enable Secure Boot for a Linux virtual machine, make sure you change the Secure Boot template to Microsoft UEFI Certificate Authority.

Ubuntu Hyper-V UEFI Secure Boot Settings

You can now start the Ubuntu VM.

Start Ubuntu hyper-V VM

 

This will boot you in the Ubuntu installation, where you can set up your Ubuntu operating system.

Install Ubuntu VM

All the specific Hyper-V drivers for Ubuntu, are already included in the image. This allows you to use features like Hyper-V Enhanced Session Mode, which enables you also to use copy-paste, and others.

Ubuntu VM on Windows 10

I hope this gives you a step-by-step guide, how you can create an Ubuntu VM on Windows 10 using Hyper-V. If you have any questions, please let me know in the comments.



Azure Bastion Windows VM

Azure Bastion – Private RDP and SSH access to Azure VMs

Azure Bastion is a new service which enables you to have private and fully managed RDP and SSH access to your Azure virtual machines. If you wanted to access your Azure virtual machines using RDP or SSH today, and you were not using a VPN connection, you had to assign a public IP address to the virtual machine. You were able to secure the connection using Azure Just in Time VM access in Azure Security Center. However, this had still some drawbacks. With Azure Bastion you get a private and fully managed service, which you deploy to your Virtual Network, which then allows you to access your VMs directly from the Azure portal using your browser over SSL.

Azure Bastion Architecture

Source: Microsoft Docs

Azure Bastion brings a couple of advantages

  • Removes requirement for a Remote Desktop (RDP) client on your local machine
  • Removes element for a local SSH client
  • No need for local RDP or SSH ports (handy when your company blocks it)
  • Uses secure SSL/TLS encryption
  • No need to assign public IP addresses to your Azure Virtual Machine
  • Works in basically any modern browser on any device (Windows, macOS, Linux, etc.)
  • Better hardening and more straightforward Network Security Group (NSG) management
  • Can remove the need for a Jumpbox

If you want to know more directly here is the link to the Azure Bastion announcement blog and the Microsoft Docs.

Public Preview

Azure Bastion is currently in public preview. The public preview is limited to the following Azure public regions:

  • West US
  • East US
  • West Europe
  • South Central US
  • Australia East
  • Japan East

To participate in this preview, you need to register. Use these steps to register for the preview:

Register-AzureRmProviderFeature -FeatureName AllowBastionHost -ProviderNamespace Microsoft.Network
 
Register-AzureRmResourceProvider -ProviderNamespace Microsoft.Network
 
Get-AzureRmProviderFeature -ProviderNamespace Microsoft.Network

To use the Azure Bastion service, you will also need to use the Azure Portal – Preview.

How to set up an Azure Bastion host for a private RDP and SSH access to Azure VMs

Create Azure Bastion Host

First, you will need to deploy Bastion Host in your virtual network (VNet). The Azure Bastion Host will need at least a /27 subnet.

AzureBastionSubnet

Access Azure virtual machines using Azure Bastion

Azure Bastion integrates natively in the Azure portal. The platform will automatically be detected if Bastion is deployed to the virtual network your virtual machine is in. To connect to a virtual machine, click on the connect button for the virtual machine. Now you can enter your username and password for the virtual machine.

Azure Portal connect to Linux VM SSH

This will now open up a web-based SSL RDP session in the Azure portal to the virtual machine. Again, there is no need to have a public IP address assigned to your virtual machine.

Private access to Azure Linux VM

 

Roadmap – more to come

As Yousef Khalidi (CVP Azure Networking) mentions in his preview announcement blog, the team will add more great capabilities, like Azure Active Directory and MFA support, as well as support for native RDP and SSH clients.

The Azure networking and compute team are doing more great work on creating a great Azure IaaS experience. I hope this gives you an overview of how you can get a private RDP or SSH access to your Azure VM. If you want to know more about the Azure Bastion service, check out the Microsoft Docs for more information. If you have any questions, feel free to leave a comment.



Microsoft Hyper-V Server 2019

Download Hyper-V Server 2019 now

A lot of people have been waiting for this. After the release of Windows Server 2019 back in October 2018, you were able to download Windows Server 2019 Standard, Datacenter and Essentials. Today you can also download Microsoft Hyper-V Server 2019. This is the free version of the Hyper-V role which you can find in Windows Server 2019. It includes all the great Hyper-V virtualization features like the Datacenter Edition. This is especially interesting if you don’t need to license Windows Server VMs, and is ideal when you run Linux Virtual Machines or VDI VMs.

This version of Hyper-V also comes with a lower footprint, since it is only available as Server Core and doesn’t include any other roles and features, which are not related to virtualization. That said, it does not come with other Software Defined Datacenter features like Storage Spaces Direct (S2D). These features are only included in the Windows Server Datacenter edition.

Microsoft Hyper-V Server is a free product that delivers enterprise-class virtualization for your datacenter and hybrid cloud. Microsoft Hyper-V Server 2019 provides new and enhanced features that can help you deliver the scale and performance needs of your mission-critical workloads.

The Windows hypervisor technology is the same as what’s in the Hyper-V role on Windows Server 2019. It is a stand-alone product that contains only the Windows hypervisor, a Windows Server driver model, and virtualization components. It provides a simple and reliable virtualization solution to help you improve your server utilization and reduce costs.

You can download Microsoft Hyper-V Server 2019 ISO from the Microsoft Evaluation Center. You should also have a look at the Windows Admin Center, which is a locally deployed, browser-based app for managing servers, clusters, hyper-converged infrastructure, and Windows 10 PCs

If you want to learn more about the new Hyper-V and Windows Server 2019 features, check out my blog: Windows Server 2019 – What’s coming next



Install WSL 2

Install WSL 2 on Windows 10

With the Windows 10 Insider Preview Build 18917, the team also ships the first version of the Windows Subsystem for Linux 2 (WSL 2), which was announced at the Microsoft Build 2019 conference. In this post, I am going to show you how you can install WSL 2 on your Windows 10 machine.

The Windows Subsystem for Linux (WSL 1) was in Windows 10 for a while now and allowed you to use different Linux distros directly from your Windows 10 machine. With WSL 2, the architecture will change drastically and will bring increased file system performance and full system call compatibility. WSL 2 is now using virtualization technology (based on Hyper-V) and uses a lightweight utility VM on a real Linux kernel. You can find out more about WSL 2 in the release blog or on the Microsoft Docs Page for WSL 2.

WSL 2 Architecture

Requirements

To install WSL 2, you will need the following requirements:

Install WSL 2

To install the Windows Subsystem for Linux 2 (WSL 2), you need to follow these tasks.

  • Enable the Windows Subsystem for Linux Optional feature (WSL 1 and WSL 2)
  • Install a distro for the Windows Subsystem for Linux
  • Enable the ‘Virtual Machine Platform’ optional feature (WSL 2)
  • Configure the distro to use WSL 2

Enable the Windows Subsystem for Linux

To run the WSL on Windows 10 you will need to install the optional feature:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

Install a Linux distro for the Windows Subsystem for Linux

If you don’t already have installed a WSL distro, you can download and install it from the Windows 10 store. You can find more here: Crazy times – You can now run Linux on Windows 10 from the Windows Store

Enable the Virtual Machine Platform feature

WSL 2 Enable Virtual Machine Platform

WSL 2 Enable Virtual Machine Platform

To make use of the virtualization feature for WSL 2, you will need to enable the optional Windows feature. You can run the following PowerShell command to do this. You will need to start PowerShell as an Administrator. After you run this command, you might need a restart of your computer.

Enable-WindowsOptionalFeature -Online -FeatureName VirtualMachinePlatform

Set WSL distro to use version 2

After you completed the first two steps, you will need to configure the distro to use WSL 2. Run the following command to list the available distros in PowerShell:

wsl -l -v

To set a distro to WSL 2 you can run the following command:

wsl --set-version DistroName 2

You can also set WSL 2 as the default:

wsl --set-default-version 2

To find out more about installing WSL 2, check out the Microsoft Docs page.

If you are now running your distro using WSL 2, you can now see that there is a Virtual Machine worker process running and if you search a little bit more, you can also find the VHDX file of the distro.

WSL 2 VHDX file

I hope this helps you and gives you a quick overview, if you have any questions, let me know in the comments and check out the WSL 2 FAQ. The Windows Subsystem for Linux 2 Kernel is also open-source, you can follow the project on GitHub.

By the way, you can now also start using Docker Desktop together with the Windows Subsystem for Linux 2.
