How to Create the External switch in the Hyper-V manager in Azure VM.

Question

Hello Team,

I've set up a VM in Azure using the D8as_V5 size, which supports nested virtualization. I've installed the Hyper-V role on it with Windows Server 2019 OS.

I can create internal switches and enable internet access for virtual machines in Hyper-V Manager. However, I'm encountering issues when attempting to RDP from other servers.

When trying to create an external switch, it shows the network is connected but lacks an internet option.

My objective is to enable internet access for virtual machines in Hyper-V Manager and establish RDP connections from other servers within the same Virtual Network in Azure.

Hello,

Thank you for posting in Q&A forum.

I suggest you try the following powershell command to create a virtual external switch which should resolve your issue:

1. Click on the "Start Menu", enter PowerShell, right-click and select Run as administrator.
2. Type the following command to create a new external virtual switch.

New-VMSwitch -Name ExternalSwitch -NetAdapterName Ethernet -AllowManagementOS $True

-name: What the network adapter looks like in Hyper-V Manager.

-NetAdapterName: The name of the network adapter.

-AllowManagementOS – $true for both the host and the virtual machine with internet.
