Requirements for a host machine for Hyper-V deployments

Last Updated : Jun 08, 2026 |

The following table lists the requirements for a computer that will host a Microsoft Hyper-V virtual machine with Avaya Aura® Device Services:

Resource

Requirement

RAM memory

13 to 19 GB:

  • 4 GB to operate the Hyper-V host.

  • 9 to 15 GB depending on the Avaya Aura® Device Services resource profile that you are planning to use.

Hard disk

At least 252 GB of free disk space:

  • 250 GB for an Avaya Aura® Device Services virtual machine.

  • 2 GB to operate the Hyper-V host.

CPU

The minimum CPU speed is 2.1 GHz per core.

The number of vCPUs that your physical CPU provides must be greater than the number of vCPUs required by the resource profile that you are planning to use. You can find the number of vCPUs that your physical CPU can provide using the following formula:

(Threads × Cores) × Physical CPU = Number of vCPU

For example, the number of vCPUs for a 4 cores / 8 threads physical CPU is (8 threads × 4 cores) × 1 CPU = 32 vCPU

NICs

Two NIC ports:

  • One NIC port for Hyper-V access and management.

  • One NIC port for routing the virtual machine network.

Operating system

The following 64-bit operating systems are supported:

  • Windows:

    • Windows 8.1

    • Windows 10

  • Windows Server:

    • Windows Server 2008 SP2 or later
