There are many security considerations built in to shielded VMs, from secure provisioning to protecting data at rest. Even administrators can’t use VMConnect.exe to connect to a Shielded Virtual Machine. Each shielded VM has a Key Protector which contains one owner guardian, and one or more HGS guardians. In short, even if the administrator of the hypervisor host is compromised, all the existent virtual machine data is safe. Shielded VMs, or Shielded Virtual Machines, are a security feature introduced in Windows Server 2016 for protecting Hyper-V Generation 2 virtual machines (VMs) from unauthorized access or tampering by using a combination of techniques like Secure boot, Bit-locker encryption, virtual Trusted Platform Module and the Host Guardian Service. Microsoft Hyper-V Shielded VM: A Microsoft Hyper-V Shielded VM is a security feature of Windows Server 2016 that protects a Hyper-V second-generation virtual machine (VM) from access or tampering by using a combination of Secure Boot, BitLocker encryption, virtual Trusted Platform Module (TPM) and the Host Guardian Service.

When deploying a new VM from template, whether it be shielded or not, a template disk is used as the basis for the VM’s operating system disk. Hyper-V runs each virtual machine in its own isolated space, which means you can run more than one virtual machine on the same hardware at the same time. 2.) A second computer (Windows 10 or Windows Server 2016) capable of running Hyper-V Manager to connect to the running VM's console; An ISO image for one of the supported Linux shielded VM OSes: Ubuntu 16.04 LTS with the 4.4 kernel; Red Hat Enterprise Linux 7.3; SUSE Linux Enterprise Server 12 Service Pack 2; Internet access to download the lsvmtools package and OS updates [!IMPORTANT] … Shielded VMs are encrypted and only run on hosts that have passed a hardware attestation process. … Shielded VM.

At an elevated command prompt, type: 1. certutil-viewstore "Shielded VM Local Certificates" You’ll be presented with a dialog that shows the Shielded VM Encryption Certificate. However, the steps illustrated below allow you to deploy and validate the entire scenario without a fabric manager. By Microsoft Windows Server Team. Note: For the full list of operating systems that Shielded VM supports, see Images with Shielded VM support. Minimum requirement to set up a guarded fabric consists of One Windows 2012/2016 physical/virtual machine to provision fabricated domain controller, One Windows 2016 DC physical/virtual machine to provision Host Guardian Service (HGS), One Windows 2016 DC physical machine to provision guarded hosts, and one or more shielded virtual machines (Generation 2 VMs) provisioned on the guarded … What Windows Server 2016 Shielded VMs include: Shielded VM mode. If the host is not connected to the network, the shielded VM won’t start. The disk signature is computed by hashing every sector of the OS volume on the template disk. The event gets generated every time the shielded VM powered on. Windows Server 2016 introduces the shielded VM feature in Hyper-V. Tenant customisation options are also limited. The CERTUTIL.EXE program is available on any system, including those without a GUI. I run Hyper-V on Windows 10, and have a Windows 10 VM that I have TPM passthrough enabled (for security reasons).

When setting the Shielding option for the VM, you’ll need to ensure that the VM is BitLocker-encrypted and accessible via RDP for management as well as PowerShell Remoting. To rectify this, I had to do the following: 1.) VMM) to deploy shielded VMs. Viewing Shielded Virtual Machine Certificates Using CERTUTIL.EXE. You can deduce then if a shielded VM's vTPM is either lost or cannot be decrypted, the shielded VM's BitLockered disk also can't be decrypted. In Windows Server 2016, you can protect hosts and guest VMs with guarded fabric that uses a Host Guardian Service to manage shielded VMs. … The VM EKpub information is stored in the eventlog channel “Microsoft-Windows-Hyper-V-Worker-Analytic”, with Event ID 1500. … Previously, Windows Client only supported local mode; HGS mode support was added in the Windows 10, version 1709 release.
