Connected Machine agent prerequisites

This topic describes the basic requirements for installing the Connected Machine agent to onboard a physical server or virtual machine to Azure Arc-enabled servers. Some onboarding methods may have additional requirements.

Supported environments

Azure Arc-enabled servers support the installation of the Connected Machine agent on physical servers and virtual machines hosted outside of Azure. This includes support for virtual machines running on platforms like:

  • VMware (including Azure VMware Solution)
  • Azure Stack HCI
  • Other cloud environments

Azure Arc-enabled servers do not support installing the agent on virtual machines running in Azure, or on virtual machines running on Azure Stack Hub or Azure Stack Edge, as they are already modeled as Azure VMs and able to be managed directly in Azure.


For additional information on using Arc-enabled servers in VMware environments, see the VMware FAQ.

Supported operating systems

The following versions of the Windows and Linux operating system are officially supported for the Azure Connected Machine agent. Only x86-64 (64-bit) architectures are supported. x86 (32-bit) and ARM-based architectures, including x86-64 emulation on arm64, are not supported operating environments.

  • Windows Server 2008 R2 SP1, 2012 R2, 2016, 2019, and 2022
    • Both Desktop and Server Core experiences are supported
    • Azure Editions are supported when running as a virtual machine on Azure Stack HCI
  • Windows IoT Enterprise
  • Azure Stack HCI
  • Ubuntu 16.04, 18.04, 20.04, and 22.04 LTS
  • Debian 10 and 11
  • CentOS Linux 7 and 8
  • Rocky Linux 8
  • SUSE Linux Enterprise Server (SLES) 12 and 15
  • Red Hat Enterprise Linux (RHEL) 7, 8 and 9
  • Amazon Linux 2
  • Oracle Linux 7


On Linux, Azure Arc-enabled servers install several daemon processes. We only support using systemd to manage these processes. In some environments, systemd may not be installed or available, in which case Arc-enabled servers are not supported, even if the distribution is otherwise supported. These environments include Windows Subsystem for Linux (WSL) and most container-based systems, such as Kubernetes or Docker. The Azure Connected Machine agent can be installed on the node that runs the containers but not inside the containers themselves.


If the Linux hostname or Windows computer name uses a reserved word or trademark, attempting to register the connected machine with Azure will fail. For a list of reserved words, see Resolve reserved resource name errors.


While Azure Arc-enabled servers support Amazon Linux, the following features are not supported by this distribution:

  • The Dependency agent used by Azure Monitor VM insights
  • Azure Automation Update Management

Software requirements

Windows operating systems:

Linux operating systems:

  • systemd
  • wget (to download the installation script)
  • openssl
  • gnupg

Required permissions

The following Azure built-in roles are required for different aspects of managing connected machines:

  • To onboard machines, you must have the Azure Connected Machine Onboarding or Contributor role for the resource group in which the machines will be managed.
  • To read, modify, and delete a machine, you must have the Azure Connected Machine Resource Administrator role for the resource group.
  • To select a resource group from the drop-down list when using the Generate script method, as well as the permissions needed to onboard machines, listed above, you must additionally have the Reader role for that resource group (or another role which includes Reader access).

Azure subscription and service limits

Azure Arc-enabled servers support up to 5,000 machine instances in a resource group.

Before configuring your machines with Azure Arc-enabled servers, review the Azure Resource Manager subscription limits and resource group limits to plan for the number of machines to be connected.

Azure resource providers

To use Azure Arc-enabled servers, the following Azure resource providers must be registered in your subscription:

  • Microsoft.HybridCompute
  • Microsoft.GuestConfiguration
  • Microsoft.HybridConnectivity
  • Microsoft.AzureArcData (if you plan to Arc-enable SQL Servers)

If these resource providers are not already registered, you can register them using the following commands:

Azure PowerShell:

Set-AzContext -SubscriptionId [subscription you want to onboard]
Register-AzResourceProvider -ProviderNamespace Microsoft.HybridCompute
Register-AzResourceProvider -ProviderNamespace Microsoft.GuestConfiguration
Register-AzResourceProvider -ProviderNamespace Microsoft.HybridConnectivity

Azure CLI:

az account set --subscription "{Your Subscription Name}"
az provider register --namespace 'Microsoft.HybridCompute'
az provider register --namespace 'Microsoft.GuestConfiguration'
az provider register --namespace 'Microsoft.HybridConnectivity'

You can also register the resource providers in the Azure portal.
