This mode of attestation requires that each Hyper-V host support UEFI 2.3.1 revision C or later and TPM v2. Since a virtual machine is a file in terms of storing in a storage, it has to be safeguarded against attacks via the storage system, the network or while it is backed up. For the purposes of this guide, we’ll be using self-signed. You’re now ready to deploy your first shielded VM. Notice that you’re new template also shows that it’s for deploying shielded or encryption supported VMs. We’re not going to deploy a shielded VM just yet as we’ll need a Shielding Data file for that. There are exactly two mutually-exclusive modes which we’ll discuss in the next section. In Windows Azure Pack, the experience is even easier than creating a regular VM because you only need to supply a name, shielding data file (containing the rest of the specialization information), and the VM network. From
, Once the VM is up and running, log into the desktop, complete any setup steps and make sure the VM is in a working state. I figured out what my problem was finally. BitLocker is also installed on the disk’s operating system to prepare it for encryption during the VM provisioning process. Trying to do the same from Hyper-V manager gives us a little more insight into why this is: You’ll also notice that you can’t see what’s going on inside the VM from its preview window. This will allow you to console onto the VM and troubleshoot what’s causing the issue. Finally, they tell HGS which security groups are deemed trustworthy. To create the private cloud environment that hosts our HVA resources, we use Windows Server 2016, System Center Virtual Machine Manager, and Windows Azure Pack. the Set-VMHost cmdlet F . Server1 has a virtual machine named VM1 that uses a single VHDX file. Click “Browse” to select a storage path and name for your .PDK, Select “Shielding data for existing VMs and non-Shielded templates”, “Shielded” and click “Next”, Select the local guardian you created earlier from the drop-down and highlight the hoster guardian you imported earlier from the windows below it. The HGS role is now installed but it’s not yet initialized. the Mount-VHD cmdlet B . HGS01: This is a standalone HGS Server that will be unclustered because this is a test environment. This means that you’ll spend at least a little time configuring an environment (or several environments) to your liking. Deploying shielded VMs This section describes how to deploy shielded VMs in VMM 2016. Remember that shielding helper VHDX we created earlier? You can avoid this by creating a new (blank) VHD and installing Windows Server 2016 onto it using your ISO installation media. What are shielded virtual machines and how to set them up in Windows Server Virtualization can expose data and encryption keys to hackers. Top 5 Reasons to Deploy Windows Server 2016 Oct 21, 2016 by Aidan Finn This product This page. It would be nice to hear what they come back with. Also, what version of SCVMM are you running? With this mode of attestation, HGS does not check for Secure Boot or code integrity policies on the host, instead, it simply examines the host’s group membership. You’ll need to have already configured a library server within SCVMM, if you’ve yet to do this, I’ve documented the process, Create and Prepare VM Shielding Helper VHD, The first thing weâll need to do is prepare an OS disk that we’ll run through the “Template Disk Wizard” RSAT tool. I also just noticed that hovering over the progress bar will show you the completion percentageâ¦nice touch ð. Setting that up is out of scope for this guide but will be covered in a later one. Apologies if that’s not a great help but it’s not a part of the process I’ve ever seen fail. To create our local guardian, click “Manage Local Guardians” and “Create”. the Set-VMProcessor cmdlet If you’d prefer not to, you can also create a shielded VM using PowerShell alone, as demonstrated in the Step by step – Creating shielded VMs without VMM blog. Virtual machines running in Google’s data center. Being that this will always be done by the tenant, lets act like one and run all this from a desktop machine. Create a new shielded VM using a signed virtual machine hard disk (VHDX), and optionally a VM template. 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. Thank you. The web giant introduced Shielded VMs as an option in mid-2018. Maintaining a fabric of regular virtual machines on any hypervisor platform pretty much boils down to the same set of administrative and operational tasks & duties: backup the VM definitions, backup their disks, etc. Give your guardian a name and either generate self-signed certificates or select existing certificates you already own. Step 6: Creating a shielded VM. View all page feedback. © Microsoft. Deploy virtual machines featuring up to 416 vCPUs and 12 TB of memory. NOTE: Tenants will be able to see details of the certificate when looking at the VSC of the disk (they’ll use this when creating their shielding data later), Armed with a certificate and prepared VHDX, we can launch the “Template Disk Wizard”, you’ll find it under “Windows Administrative Tools” in the Start menu, On the “Certificate” screen, click “Browse” and select the certificate you created above and click “OK”. We’re going to cover creating a shielded template disk and a VM template that makes use of it. Now click “Finish”. This however does allow me to reiterate that without networking, a shielded VM is basically a brick ð. AD-based attestation uses Active Directory security groups to assess health. If the template disk is later infected by malware, its signature will differ and cause the shielded VM provisioning process to abort creation. Copy your new Shielding Data File to your SCVMM server and import it following the process we used above. The IP Address is 10.0.0.6 2. For HGS to release a key to Hyper-V, the request must be accompanied by a trustworthy, non-expired certificate of health. If you re-use a template disk, there will be a disk signature collision during the shielding process because both disks will have the same GPT disk identifier. Initializing HGS is really all about two things: selecting the certificates used to protect shielded VMs and configuring HGS’ attestation mode. The scope of this blog is limited to minimal configuration to setup Host Guardian Service role and the corresponding Hyper-V support components to provision a Shielded VM in the guarded host. As noted earlier, HGS supports precisely two attestation modes: TPM-based attestation is the preferred choice because it imposes stringent cryptographically-enforced health requirements on hosts before releasing the keys they need to work with shielded VMs. Before you start So it’s good news that we can also create templates for our shielded VMs. In this section we’re going to configure all necessary resources to enable us to deploy shielded VMs on our guarded fabric. Now let’s briefly walk through creating a shielded VM template disk and a shielding data file so that we can provision shielded VMs simply and securely on the fabric we just built. I’m glad you managed to resolve the issue. ... Shielded VMs Reinforced virtual machines on Google Cloud. You’ll notice that when you RDP, you see a popup which shows the RDP certificate you placed in your shielding data file, so that works! shielded virtual machines . A fabric admin creates or designates a group in the fabric Active Directory domain and adds each of the trusted Hyper-V hosts (the computer accounts) to that group. The VSC is signed using a certificate specified by either the tenant or the service provider (depending on who is supplying the template disk, as it can all be done by the tenant if that’s their preference) and is used in the provisioning process to ensure that the disk has not been altered or replaced with a disk the tenant hasn’t trusted. Thanks for passing your fix on, much appreciated. Once the VM has finished sysprepping (yeah it’s a word! Log onto your SCVMM server, launch an elevated PowerShell console and run the following: â¦and with that, we can FINALLY create the tenants shielding data file. Join me in part 7 where I’ll be detailing how to offer this service to tenants via the Windows Azure Portal. How to create and deploy a virtual machine in Microsoft Azure by Mark Kaelin in Cloud on February 8, 2019, 10:30 AM PST Deploying VMs using the Microsoft Azure Portal takes just … Now click “Next”, On the “Volume ID Qualifiers” page and click “Add”Click “Browse” to locate the .VSC file you obtained earlier and click “OK”. Now click “OK”. You may also receive an error relating to your configured Execution Policy, this can be set to the following values: You can set this to “Unrestricted” long enough to allow you to install the module by running. Microsoft have made their RSAT tools available for download and install for Windows 10. The added security of these templates does require a little more effort to setup, but that’s what we’re here to step through ð. WS-Man is enabled by default and the above rules can be added by using, Armed with a certificate and prepared VHDX, we can launch the, Give your disk a friendly name and a version number (yup, 3 decimal places) and click, Copy the VHDX to your SCVMM library share folder, this could be local on the server or if you used this guide a dedicated share on your SOFS cluster, (Iâve yet to update my VMM deployment with this piece, coming very soon), You can also right-click the context bar at the top of the pane and enable a column for denoting resources as, Select your signed template disk, you can make this earlier by right-clicking the context bar and enabling a, Type a name for your VM Template and click, Modify the resources as required, Processors, Memory and Availability. For a guarded fabric, however, there’s a small number of artifacts that are specific to running and maintaining shielded VMs: Introducing Shielded Virtual Machines (VMs) Windows Server 2016 Shielded VMs remedy this disconcerting situation by extending virtual machines the same security capabilities that physical machines have enjoyed for years, e.g. You can find the video here: Deploying shielded VMs and a guarded fabric with Windows Server 2016 . Now click “Next”, On the “Specialization Files” page, click “Browse” and locate the unattend file you created earlier. Once the refresh job has completed, you should see the new shielded VHDX in your libraryâ¦and hey LOOK, it’s got a shielded icon ð, You can also right-click the context bar at the top of the pane and enable a column for denoting resources as “Shielded”. 2 Introduction to Windows Server 2016 Shielded VMs Abstract This document provides step-by-step instructions on how to deploy Shielded Virtual Machines (VMs) and Guarded Fabric on Lenovo® servers running Windows Server 2016 Datacenter Edition. Log onto the server you used earlier for signing your template disk (as it already has the required RSAT tools installed). Now log onto the server and install the Shielded VM RSAT Tools using the PowerShell below: 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. Navigate to “Library”, right-click “VM Templates” and select “Create VM Template”, Select “Use and existing VM template or virtual hard disk stored in the library” and click “Browse”, Select your signed template disk, you can make this earlier by right-clicking the context bar and enabling a “Shielded” column. The main differences being that options like Generation 2, UEFI, secure boot etc. Let’s finish up with the hoster side of things before moving on to that ð. Select the host group that contains your guarded hosts and click “Next”.Select a host and click “Next”. Select your .PDK and click, During this process you will see a new virtual machine is created called, So there you have it, you can now deploy shielded VMs to your guarded fabric. In a traditional environment where virtual machines run on a hypervisor host, it’s possible for the administrator of the virtualization layer to get full access to the virtual machines. Join me in, Click to share on Twitter (Opens in new window), Click to share on Facebook (Opens in new window). The wizard is included with the Shielded VM Tools feature in Windows Server 2016 Remote Server Administration Tools, and the Windows 10 Remote Server Administration Tools package. Sounds good! You plan to use VM1 as a virtual Machine Template to deploy shielded virtual machines. Click “Browse” and select the ShieldingHelper VHDX you just copied to the library. This article describes how to deploy shielded virtual machines in the System Center - Virtual Machine Manager (VMM) compute fabric. Since the Hyper-V hosts don’t persistently store these keys, they must ask HGS for them whenever a shielded VM is powered on or when receiving a shielded VM through live migration. DC1: This VM is the Domain Controller for the following AD Forest: GET-CMD.local. If you look at any datacenter today, virtualization is a key element. You can use any of your existing tools to create this disk (DISM for example), however I always prefer to create a new VM from ISO and will be using this process now. Virtual machines running in Google’s data center. The first .PDK we’re going to create will be for fully shielding VMs, as such, click “Shielded” and click “Next”. HGS is now able to validate that each host’s EKpub, TCGlog and CI policy match with its whitelisted inventory before issuing a health certificate. I ran the template disk wizard and the vhdx was bitlocked. Deploying a guarded fabric involves several new concepts so, in this blog, we’ll describe each of the pieces including what it does, any specific requirements, their relative sequence, and point you to the cmdlet used to complete each step. NOTE: Don’t copy the VHDX to your VMM library just yet. Get up to 3.7 million local storage IOPS per VM. Before creating our disk though, there are a few requirements to be aware of, see table below: With all of that in mind, go spin up a VM so we can steal it’s disk ð. This will allow us to keep the VM for usage somewhere else later, including updating it as once it’s been signed, you will not be able to alter it. A trustworthy administrator, such as the fabric administrator or VM owner, will need a signing certificate to create the disk signature. NOTE: Make sure you’re SCVMM setup is in line with the warning detailed in the screenshot below: To get the VSC file, log onto your SCVMM server and launch an elevated PowerShell prompt and run the following: This code assumes that you only have one signed disk in your SCVMM library at the time of running, if this is not the case, modify the first line as follows: NOTE: As previously mentioned, a tenant would generally download this file from the Windows Azure Pack portal. For the purposes of this guide, we’ll be obtaining this using an SCVMM PowerShell cmdlet. Which type virtual machine should you deploy? Google has made its Shielded VMs the default option in its cloud. With virtual machines we’ve made it easier to deploy, manage, service and automate the infrastructure. NOTE: Now delete the VM you used to create the ShieldingHelper disk as starting it up again will corrupt the ShieldingHelper disk. For this, we need to get a hold of the guardian metadata. Make sure you attach your network adapter to a VM Network as this is a tenants only route into a shielded VM. This gives us as the owner of a VM, the ability to change it from Shielded to Encryption Supported and vice versa. You can use the New device drop-down menu on the Customize Hardware page to add a new hard disk, select an existing disk, or add an RDM disk.
