Error Occurred Trying to Retrieve a List of Virtual Switches

Question

I tried every possible solution but stuck here. I tried to follow this: https://appuals.com/an-error-occurred-virtual-switches-in-hyper-v-2019/ but could not see the protocol, or the network card here. I am new with Hyper-v so take it easy.

Hello,

 

Thank you for posting in Q&A forum.

To further troubleshoot this issue, please kindly try below steps:

1.Find the network interface and right click to open properties > Check Hyper-V Extensible Virtual Switch and click Install > Select Protocol and click "Add" > Select network protocol > Reliable Multicast Protocol > click OK.

After the change please reboot the machine to get it applied.

2.You can also create a virtual switch in PowerShell command:

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

3.Reinstall Hyper-V role, give another try and check if issue still persists.

4.Meanwhile you can try to reinstall the network Adapter.

 

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.

 

Best regards，

Jill Zhou
