In Hyper-V Manager, select your Ubuntu virtual machine, right click the VM name and in the context menu, select Connect to open VMConnect. When you boil down a Shielded VM to its absolute most basic security foundation it is the ability to decrypt the content of the virtual TPM (vTPM) that is stored in the VMs resource state file (VMRS). With Shielded VM’s we can add a Virtual TPM module to each VM and use that to encrypt the content of the Virtual Machine. Table 1 Examples of attacks that Shielded VMs can defend against This document provides guidance for deploying a guarded fabric, that is, the Host Guardian Service (HGS) plus guarded hosts, on which Shielded VMs can run. Now log onto the server and install the Shielded VM RSAT Tools using the PowerShell below: Install-WindowsFeature RSAT-Shielded-VM-Tools –Restart You will now need to obtain a certificate to sign the VHDX, for production purposes, this certificate should be from a Certificate Authority trusted by both the tenant and the hoster.
