Red Hat Enterprise Linux virtual machine deployment in Microsoft Azure

Last Updated : Jun 05, 2026 |

When you deploy Avaya Aura® Device Services as a software-only solution, you must use the Red Hat Enterprise Linux (RHEL) 8.4 or RHEL 8.10 (LVM) GEN1 or GEN2, which is available in Microsoft Azure Marketplace.

After obtaining RHEL 8.4 or RHEL 8.10, do the following:

  1. Deploy a RHEL 8.4 or RHEL 8.10-based virtual machine in Microsoft Azure. For more information, see Create a Linux virtual machine in Azure.

    When creating a virtual machine, use the virtual machine size that is appropriate for the Avaya Aura® Device Services resource profile that you selected. For information about virtual machine sizes, see Resource profile specifications for Microsoft Azure virtual machines.

    For cluster deployments, you can deploy virtual machines in different subnets and in different Availability Zones as appropriate.

    Important:

    • Avaya Aura® Device Services requires 250 Gb of free disk space in total. Microsoft Azure virtual machines might not have the required amount of disk space by default. Before deploying RHEL, ensure that virtual machines have enough disk space and purchase additional disk space if required.

      By default, the size of the primary hard disk of a virtual machine does not equal to the required size of 125 Gb. You must resize the disk during or after virtual machine deployment.

      Avaya Aura® Device Services requires specific disk partitioning. After installing RHEL, you must create the required data disks and physical volumes for data disks as described in Creating required virtual hard disks for a virtual machine and Creating disk partitioning for a Microsoft Azure virtual machine.

    • During the RHEL installation process, you create primary network interface eth0. Do not modify the ifcfg-eth0 configuration file before installing the system layer. Avaya Aura® Device Services deployment might fail if you modify this file before installing the system layer. You can freely modify this file after you install the system layer.

  2. Install the latest critical security updates.

    For update procedures, see Red Hat documentation. You can install security updates by using the YUM package manager.
