The following command creates a Windows Server 2016 VM: Attach the network interface that you previously created with Add-AzVMNetworkInterface: Once you create the VM in Azure, connect to the VM and confirm that the Ethernet controller is installed in Windows. First, stop the VMs: Once the VMs are stopped, update the Accelerated Networking property under the network interface: Please note, a VMSS has VM upgrades that apply updates using three different settings, automatic, rolling and manual. Accelerated Networking is available for Virtual Machine instances that have two or more vCPUs for general purpose VM series (D/DSv2) and compute optimized Virtual Machine M series (F/Fs). If you receive output similar to the following sample output, accelerated networking is enabled and working. In these instructions the policy is set to automatic so that the VMSS will pick up the changes immediately after restarting. Only supported operating systems can be enabled through the portal. Instead, to resize one of these VMs: Stop or deallocate the VM. In the supported VM instances and Operating system (CentOS 7.4 which supported) you should be able to see the Accelerated Networking option when you create a VM on portal. The VM must support Accelerated Networking by meeting the following prerequisites that are also outlined above: First stop/deallocate the VM or, if an Availability Set, all the VMs in the Set: Important, please note, if your VM was created individually, without an availability set, you only need to stop/deallocate the individual VM to enable Accelerated Networking. We have noticed that ACI works well for their scenario but the Networking could be improved. The following distributions are supported out of the box from the Azure Gallery: Accelerated Networking is supported on most general purpose and compute-optimized instance sizes with 2 or more vCPUs. In this tutorial, you learn how to create a Linux virtual machine (VM) with Accelerated Networking. All NDv2 instances benefit from the GPU-optimized HPC applications, machine learning software and deep learning frameworks like TensorFlow, PyTorch and MXNet from the NVIDIA NGC container registry and Azure Marketplace. It is now available for all the regions. Open a port to allow SSH access to the virtual machine with az network nsg rule create: Create a public IP address with az network public-ip create. The benefits of accelerated networking have a real impact when communicating across Azure Virtual Networks (VNets) or connecting to on-premises, as this feature provides low latency and high throughput. Accelerated Networking is now enabled for your VM. o ESv3 series - this series can be Broadwell or Skylake processors. Offloading the policy enforcement to the hardware removes that variability by delivering packets directly to the VM. Enable accelerated networking on the NIC of your VM: Restart your VM or, if in an availability set, all the VMs in the set, and confirm that accelerated networking is enabled: A virtual machine scale set is slightly different, but it follows the same workflow. The returned output is similar to the following output: Check for activity on the VF (virtual function) with the ethtool -S eth0 | grep vf_ command. On instances that support hyperthreading, accelerated networking is supported on VM instances with four or more vCPUs. A supported VM size without accelerated networking enabled can only have the feature enabled when it's stopped and deallocated. The following example creates a VM named myVM with the UbuntuLTS image and a size that supports Accelerated Networking (Standard_DS4_v2): For a list of all VM sizes and characteristics, see Linux VM sizes. Create a resource group with New-AzResourceGroup. Create the rest of your VM configuration with Set-AzVMOperatingSystem and Set-AzVMSourceImage.
