While publishing through visual studio, facing the issue "The virtual machine could not be started because a required feature is not installed."

Question

Hi There,

I have created a Azure Virtual machine, windows 10 pro. Installed docker in it.
I am trying to publish a code-base for OPC Publisher Edge module to Container registry using Visual studio 2019.

The systeminfo shows the following:

"Hyper-V Requirements: A hypervisor has been detected. Features required for Hyper-V will not be displayed."

While publishing the code it throws the following error:

---

1>Step 6/17 : RUN dotnet restore "opcpublisher/opcpublisher.csproj"
1> ---> Running in a13f7240c82c
1>Removing intermediate container a13f7240c82c

Hi @Vivek Sagar Pandey ,

That systeminfo dialog is stating that your attempting to publish a virtualized artifact on-top of an existing virtualization. This is called Nested Virtualization and it's not enabled on everything by default. For how to enable nested virtualization on a VM more please see this doc.
