How to Enable Nested Virtualization on Hyper-V Windows Server 2016

I figured this post may be useful if you’re like me and testing out Azure Stack. If you are unaware of Azure Stack, in short, it allows organizations to have Azure (Cloud) on their own environment/datacenter. Here is a LINK for more information on Azure Stack. Azure Stack is currently in phase TP2 (Technical Preview 2) and this is the version I will be deploying and testing.

Anyways..

Before getting started with Azure Stack, your physical Windows Server 2016 box must have Nested Virtualization enabled.

First things first, the VM will need to have:

  • Dynamic Memory disabled and provide a minimum of 96GB of memory

3

  • VM will need to have at least 1 vCPU. I gave it 16 as per system/hardware recommendations.

4

  • MAC address spoofing must be enabled.

5

  • Lastly, Virtualization Extensions need to enabled/set to TRUE.

With the following PowerShell code, we can get the value, and then change the value from. By default this value is disabled.

Get-VMProcessor -VMName VMName | FL *
Set-VMProcessor -VMName VMName -ExposeVirtualizationExtensions $true

1

Re-run the first command to confirm the change.

Now we are ready to move forward with the Azure Stack install!

Step-by-Step – SCOM 2012 R2 Update Rollup 11 (UR11) Install Procedure

My personal notes,  SCOM 2012 R2 Update Rollup 11 (UR11) has a lot of networking monitoring fixes, Linux/UNIX support and security fixes, along with more OMS integration. What is OMS, please go HERE. It is highly recommended to upgrade your lab/Dev environments first before upgrading your Production environment(s). The step by step procedures below are the steps I took and in no way shape or form do I accept responsibility for any data loss, and/or issues within your environment. It is advised to always take a backup of your SQL databases and/or snapshots of your SCOM environment(s). Please take these notes as suggestions. Always refer to Microsoft’s KB (posted above) for full documentation steps.

Here are the key updates for UR11 (source Microsoft):

Issues that are fixed in this update rollup can be found here, https://support.microsoft.com/en-us/kb/3183990

Once you are ready to begin your upgrade, it is recommend you do the following server/roles in the order below:

  1. Install the update rollup package on the following server infrastructure:
  • Management server or servers
  • Audit Collection Services
  • Gateway servers
  • Web console server role computers
  • Operations console role computers
  1. Apply SQL scripts.
  2. Manually import the management packs.
  3. Apply the agent update to manually installed agents, or push the installation from the Pending view in the Operations console.

Once you have downloaded the rollup files, I like to extract and only keep the language I need, in this case, ENU (English). You will need to install these with Administrative rights, I like to use PowerShell as Local Administrator. It really does frustrate me, as there is no indication that the rollup installed correctly, (other than looking at the file version number change via File Explorer).

Personally, I prefer to execute the MSP files via PowerShell (RunAs Administrator) console.

Again, the order needs to be:

  1. Management Servers
  2. Audit Collection Services
  3. Gateway Servers
  4. Web Console Role Servers
  5. Operations Console Role Servers

Once the rollups are installed, you will now need to apply the SQL scripts. First update the Data Warehouse, then followed by the OpsMgr DB.

The scripts can be found here, “%SystemDrive%\Program Files\System Center 2012 R2\Operations Manager\Server\SQL Script for Update Rollups

Please note, the user executing these scripts needs to have read and write permissions to the database(s).

Once you have successfully executed the SQL scripts, you will now need to import the updated Management Packs (MP). These MPs can be found here, “%SystemDrive%\Program Files\System Center 2012 R2\Operations Manager\Server\Management Packs for Update Rollups“.

You will need to import the following MPs, please see below:

Once the MPs have been imported, you should now go back to your Pending Management view, under the Administrations pane, and update all servers.

And that is that! You are now on the latest and greatest System Center release for SCOM 2012 R2.
