Hi everybody,

another great news today. Microsoft made System Center 2016 TP5 and Windows Server 2016 TP5 available for download.

TP 5 is the last technical preview before the official release, which we think could be in Q3/Q4 2016.

Virtual Switches in Windows Server 2016 Hyper-V

With coming nearer to the release of Windows Server 2016, more and more details about he final server are revealed.

Today I want you give a short list about the switches which will be part of Hyper-V in Windows Server 2016.

“Classical” Switches

Switchtype Discription Source
Private Switch The private switch allows communications among the virtual machines on the host and nothing else. Even the management operating system is not allowed to participate. This switch is purely logical and does not use any physical adapter in any way. “Private” in this sense is not related to private IP addressing. You can mentally think of this as a switch that has no ability to uplink to other switches. http://www.altaro.com/hyper-v/the-hyper-v-virtual-switch-explained-part-1/
Internal Switch The internal switch is similar to the private switch with one exception: the management operating system can have a virtual adapter on this type of switch and communicate with any virtual machines that also have virtual adapters on the switch. This switch also does not have any matching to a physical adapter and therefore also cannot uplink to another switch. http://www.altaro.com/hyper-v/the-hyper-v-virtual-switch-explained-part-1/
External This switch type must be connected to a physical adapter. It allows communications between the physical network and the management operating system and virtual machines. Do not confuse this switch type with public IP addressing schemes or let its name suggest that it needs to be connected to a public-facing connection. You can use the same private IP address range for the adapters on an external virtual switch that you’re using on the physical network it’s attached to. http://www.altaro.com/hyper-v/the-hyper-v-virtual-switch-explained-part-1/

New Switches available in Windows Server 2016

Externals Switch with SET SET (Switch embedded Teaming) is an alternative NIC Teaming solution that you can use in environments that include Hyper-V and the Software Defined Networking (SDN) stack in Windows Server 2016 Technical Preview. SET integrates some NIC Teaming functionality into the Hyper-V Virtual Switch.SET allows you to group between one and eight physical Ethernet network adapters into one or more software-based virtual network adapters. These virtual network adapters provide fast performance and fault tolerance in the event of a network adapter failure. SET member network adapters must all be installed in the same physical Hyper-V host to be placed in a team. https://technet.microsoft.com/en-US/library/mt403349.aspx#bkmk_sswitchembedded
NAT Mode Switch With the latest releases of the Windows 10 and Windows Server 2016 Technical Preview 4, Microsoft included a new VM Switch Type called NAT, which allows Virtual Machines to have a Internal Network and connect to the external world and internet using NAT. http://www.thomasmaurer.ch/2015/11/hyper-v-virtual-switch-using-nat-configuration/

Virtual Switches in System Center Virtual Machine Manager

Switchtype Discription
Standard Switch A Standard Switch is basicly a Hyper-V Switch shown in virtual machine manager. From the management and feature perspective there are no differences.
Logical Switch A Logical Switch includes Virtual Switch Extensions, Uplink Port Profiles which define the physical network adapters used by the Hyper-V Virtual Switch for example for teaming and the Virtual Adapter Port Profiles mapped to Port Classifications which are the settings for the Virtual Network Adapters of the virtual machines.

Not really a switch but part of the Hyper-V networking stack and currently necessary in multi tenant scenarios.

Type Discription Source
Multi Tenant Gateway In Windows Server 2012 R2, the Remote Access server role includes the Routing and Remote Access Service (RRAS) role service. RRAS is integrated with Hyper-V Network Virtualization, and is able to route network traffic effectively in circumstances where there are many different customers – or tenants – who have isolated virtual networks in the same datacenter.Multi-tenancy is the ability of a cloud infrastructure to support the virtual machine workloads of multiple tenants, but isolate them from each other, while all of the workloads run on the same infrastructure. The multiple workloads of an individual tenant can interconnect and be managed remotely, but these systems do not interconnect with the workloads of other tenants, nor can other tenants remotely manage them. https://technet.microsoft.com/en-us/library/dn641937.aspx

How to upgrade SCVMM from 2012 R2 to 2016

Hi,

today I want to provide you a quick end dirty step by step guide how to upgrade you SCVMM from 2012 R2 to 2016.

The procedure is pretty much the same like in 2012 or 2012 R2.

Single Node:

  1. Uninstall SCVMM 2012 R2 and keep your database
  2. Install all needed requirements for SCVMM 2016 on your server which are noticed in the requirements* during the installation wizard
  3. Connect the “old” SCVMM 2012 R2 database
  4. Run all updates and your done

Cluster:

  1. Uninstall SCVMM 2012 R2 from all of your nodes and keep your database
  2. delete the cluster role of the old VMM (if you want to keep the name you need to set it new)
  3. Install all needed requirements for SCVMM 2016 on your server’s which are noticed in the requirements* during the installation wizard
  4. Create a new cluster role with the old name and IP
  5. Connect the “old” SCVMM 2012 R2 database
  6. Run all updates and your done

*You will require

That’s all 🙂

Save the Date: WEBINAR | Scripting & Automation in Hyper-V without SCVMM with @ThomasMaurer

Hi everyone,

you should save the 10th December 2015 in your calender’s. My friend Thomas Maurer is presenting some cool Scripting Stuff for Hyper-V together with Altaro. 🙂

Click here to register for the event.

System Center Virtual Machine Manager (SCVMM) provides some great automation benefits for those organizations that can afford the hefty price tag. However, if SCVMM isn’t a cost effective solution for your business, what are you to do? While VMM certainly makes automation much easier, you can achieve a good level of automation with PowerShell and the applicable PowerShell modules for Hyper-V, clustering, storage, and more.

Are you looking to get grips with automation and scripting?

Join Thomas Maurer, Microsoft Datacenter and Cloud Management MVP, who will use this webinar to show you how to achieve automation in your Hyper-V environments, even if you don’t have SCVMM.

Remember, any task you have to do more than once, should be automated. Bring some sanity to your virtual environment by adding some scripting and automation know-how to your toolbox.

How to fix same SMBIOS ID on different Hosts

Today one post about things I see sometimes in the field.

Today I want to show you how to fix the issue when you get servers and clients with the same SMBIOS ID. Normally that would be an issue but as soon as you try to management them with System Center Virtual Machine Manager or Configuration Manager it will become one. Both tools use the SMBIOS ID to create a primary key in their databases to identify the system.

Currently I only know the following trick to fix the issue and that one would be extremly annoying on many clients or servers but it actually work.

First you need two tools.

1: Rufus – To create a bootable USB Stick

2: AMIDMI – With that tool you can overright the SMBIOS ID

Now create the Bootstick with Rufus and copy the AMIDMI file on the stick.

Reboot your from the stick.

Navigate to the folder with your AMIDMI file and run the command amidmi /u

Afterwards you can reboot the system and start Windows again.

 

When you are working with Virtual Machine Manager, you need to remove the host from your management consolte and add it again. After the host is discovered again, you can see the new SMBIOS ID.

I currently saw these issues with following motherboard vendors:

  1. ASRock (Client & Rack)
  2. ASUS (Client)
  3. SuperMicro (Server & ARM)
  4. Fujisu (Server)
