Azure Nested Virtualization

Hyper-V Container and Nested Virtualization in Microsoft Azure Virtual Machines

Last week Microsoft announced some pretty cool new Azure Stuff, like the Azure Cloud Shell, Azure PowerShell 4.0, Azure Cosmos DB and much more.

In the session about Azure Compute, Microsoft introduced a bunch of new features, like new VM sizes, new experiences and new integration technology as well as updates to Azure Service Fabric, Azure Container Service and Azure Functions. One which really got my interest was the announcement about the new Virtual Machines sizes for Dv3 and Ev3, which will enable customers to use Virtualization inside their Windows Server Virtual Machines on Azure, enabled by Nested Virtualization from Windows Server 2016 Hyper-V. With that Dv3 and Ev3 Azure Virtual Machines are Nested Virtualization enabled.

Azure Nested Virtualization and Hyper-V Containers

You can now run Hyper-V in Azure Virtual Machines and even more important you can now run Hyper-V Container inside Azure Virtual Machines. With the announcements for Windows Server 2016 supporting Hyper-V Containers running Linux and Windows Server this is great news. You will be able to create Container Hosts in Azure running Windows Server and create Windows and Linux Containers on the same Container Host.

Azure VM Sizes

By the way, if you want to run Hyper-V Container in Azure today, and you don’t want to wait until the Dv3 and Ev3 series are available you can run them inside Azure Service Fabric. So yes, Microsoft now allows you to run Hyper-V Containers in Azure Service Fabric.

Azure Nested Virtualization Demo

As you could see in the demo, they are offering quite large Virtual Machines with a lot of RAM, running on Intels Xeon E7 CPUs.

What's new in Hyper-V 2016

Windows Server 2016 Hyper-V Scale Numbers

Yesterday Microsoft announced the VMware to Hyper-V Migration offer with Windows Server 2016. The Hyper-V team also announced the new scale numbers in Windows Server 2016 Hyper-V. Microsoft announced a Hyper-V Host will support 24TB of RAM and up to 512 CPUs, and up to 16TB and 240 virtual CPUs per Virtual Machine. This are huge number and a huge improvement to the numbers to the numbers of Windows Server 2012 and Windows Server 2012 R2.

Windows Server 2012/2012 R2

Standard & Datacenter

Windows Server 2016 Standard & Datacenter
Physical (Host) Memory Support Up to 4 TB per physical server Up to 24 TB per physical server (6x)
Physical (Host) Logical Processor Support Up to 320 LPs Up to 512 LPs
Virtual Machine Memory Support Up to 1 TB per VM Up to 16 TB per VM (16x)

VMware Switch

Microsoft’s new VMware migration offer for Windows Server 2016

Microsoft just announced a new VMware migration offer for Windows Server 2016. In a nutshell: If you switch from VMware to Hyper-V from during September 1, 2016, through June 30, 2017, you can get free Windows Server Datacenter licenses when buying Windows Server Datacenter + Software Assurance. That ultimately means customers only pay for Software Assurance.

Microsoft also released a new TCO calculator to compare VMware and Hyper-V, which you can find here: VMware Shift

There are also a lot of great technical reasons to switch from VMware to Hyper-V. Check out my blog post about What’s new in Windows Server 2016 Hyper-V to get an overview about new features.

To get started just follow these steps:

To be eligible for the VMware migration offer, customers must follow these steps:

  • Step 1: Engage your account executive or sales rep to begin the process.
  • Step 2: Identify virtualized workloads to migrate and specify the Windows Server Datacenter cores required.
  • Step 3: Provide your account executive proof of eligibility. (Offer applicable to customers migrating from VMware to Microsoft).
  • Step 4: Engage your partner to start the migration process.
  • Step 5: Receive free Windows Server Datacenter licenses with Software Assurance and pay only the cost of Software Assurance to kick start your migration.

Feel free to contact us to help you switch!

Microsoft a leader in Gartner x86 Server Virtualization Infrastructure 2016 Magic Quadrant

Year over year Microsoft is named as a leader in the Gartner x86 Server Virtualization Infrastructure Magic Quadrant and it gets closer and closer to VMware. Microsoft now is named again as a leader in Gartner x86 Server Virtualization Infrastructure 2016 Magic Quadrant. Especially the integration with System Center and Microsoft Azure as well as the new security features in Windows Server 2016 Hyper-V, makes Hyper-V a strong player in the hypervisor space. Check out the Microsoft Blog post for more information or my blog post about What’s new in Windows Server 2016 Hyper-V.

Gartner published the Gartner x86 Server Virtualization Infrastructure MQ with Microsoft landing in the Leader Quadrant for the sixth year in a row. Microsoft moved up in the ‘ability to execute’ and to the right in the ‘completeness of vision’ assessment compared with 2015. Gartner defines leaders as having a clear strategy and roadmap for offerings, understanding virtualization’s role in infrastructure and operations transformation, and having a clear vision with respect to private cloud, hybrid cloud and public cloud computing.

unatted xml file for VM

Add unattend.xml to VHDX File for VM automation

If you for example don’t have System Center Virtual Machine Manager or another tool to create Virtual Machine Templates and automate the deployment, you can also do this using Sysprep, PowerShell and an unattend.xml file to automate or simplify the Virtual Machine creation process. In other blog posts I already wrote how you can sysprep Virtual Machines or how you can create Hyper-V Virtual Machines using PowerShell. In this post I will show you how you can add an unattend.xml file to your VHD or VHDX so your virtual machine gets some default settings like regional information.

Here we have a basic unattend.xml file. If you want to enhance it, or create your own, you can also use the Windows ADK.

To use this unattend.xml you first have to sysprep a virtual machine and create a sysprep VHD file. After that you can mount the VHDX file and insert the unattend.xml file to the VHD. Copy the unattend.xml file to the following location: D:\Windows\Panther (in my case the VHD was mounted as D drive).

You can mount the VHDX using the UI or PowerShell:

There are more paths as well. You can check out the Windows Setup Automation Overview on TechNet where you can see all the possible paths to place the unattend.xml file.



sysprep.exe vm mode

Windows Sysprep for Virtual Machines

For using the same system image for different virtual machines or physical computer, Microsoft created a tool called sysprep.exe. Most people should be already familiar with that tool. If not here is the description:

Sysprep prepares a Windows installation (Windows client and Windows Server) for imaging, allowing you to capture a customized installation. Sysprep removes PC-specific information from a Windows installation, “generalizing” the installation so it can be reused on different PCs. With Sysprep you can configre the PC to boot to audit mode, where you can make additional changes or updates to your image. Or, you can configure Windows to boot to the Out-of-Box Experience (OOBE).

This is great so you can sysprep a virtual machine copy the VHD or VHDX file and use it for the first boot of different VMs. In Windows Server 2012 and Windows 8, Microsoft added an addition to sysprep called the mode switch “/mode:vm”. The mode:vm switch allows you to identify the Windows as a Virtual Machine and sysprep.exe will generalize a Virtual Hard Disk (VHD or VHDX) so that you can deploy the VHD as a VHD on the same Virtual Machine (VM) or hypervisor. You must deploy the VHD on a Virtual Machine (VM) or hypervisor with the same hardware profile. For example, if you created VHD in Microsoft Hyper-V, you can only deploy your VHD to Microsoft Hyper-V VMs with a matching hardware profile, and you can only run VM mode from inside a VM.

This will boost the performance and time for the virtual machine for the first startup and installation. This also work of course with virtual machines running on other hypervisors such as VMware or Xen.

Run the following command inside the Virtual Machine (You find sysprep.exe in the  C:\Windows\System32\Sysprep folder):

Now you can copy the VHD or VHDX file from that virtual machine and use it for other VMs.
