Several key IT trends have been reshaping the industry, notably Cloud and Big Data. As business innovations drive the need for enhanced systems, the data that IT must track grows exponentially and creates significant challenges. Without the right tools for visualizing data, significant and valuable insights remain unknown. In fact, the utter volume of data prevents organizations from capturing, analysing and presenting information that is significant…

Last October, Microsoft and Docker, Inc. jointly announced plans to bring containers to developers across the Docker and Windows ecosystems via Windows Server.
Hyper-V Containers will ensure code running in one container remains isolated and cannot impact the host operating system or other containers running on the same host. Applications developed for Windows Server Containers can be deployed as a Hyper-V Container without modification, providing greater flexibility for operators who need to choose degrees of density, agility, and isolation in a multi-platform, multi-application environment.
The new Microsoft Container technology offers flexibility and choice through Windows Server containers, Linux containers, and Hyper-V containers both in the cloud and on-premises.
Microsoft Announces Nano Server for Modern Apps and Cloud in vNext. Nano Server won’t have a separated SKU, it will be an installation option during Windows Server vNext deployment.
Nano Server is a deeply refactored version of Windows Server with a small footprint and remotely managed installation, optimized for the cloud and a DevOps workflow.
There is no local logon or Remote Desktop support. All management is performed remotely via WMI and PowerShell.
Nano Server focuses on two scenarios:
- Born-in-the-cloud applications – support for multiple programming languages and runtimes. (e.g. C#, Java, Node.js, Python, etc.) running in containers, virtual machines, or on physical servers.
- Microsoft Cloud Platform infrastructure – support for compute clusters running Hyper-V and storage clusters running Scale-out File Server
EXCLUSIVE Whitepaper: Microsoft Hyper-V Performance
Businesses worldwide are turning their attention to Microsoft’s Hyper-V platform when they’re looking at their private and hybrid cloud initiatives. Find specific and concrete advice in this whitepaper to help you design, build, and upgrade Hyper-V deployments.
Find out how you can get the best value from your Hyper-V deployments, register now for our webinars “Microsoft Hyper-V Performance Considerations” by IT expert Paul Schnackenburg. The webinars will be co-hosted by Savision’s Technical Sales Engineer, Justin Boerrigter.
During the webinar, you will find out how to design, build, and upgrade Hyper-V deployments to ensure that workloads have adequate resources and don’t experience performance issues. Get all the information you need on tools and techniques that will help you locate and remove resource bottlenecks when planning a Hyper-V fabric rollout.

In case you did not read the Microsoft KB, after applying Update Rollup 4 for Virtual Machine Manager (http://support.microsoft.com/kb/2992024), make sure you manually update all VMM Hyper-V hosts and the VMM Console.
Note: If this component is not updated, virtual machines may not be assigned an IP address for several minutes when the lease expires or after restarting the VM.
Install the updates in the following order:
1. Update Rollup 4 for the Administrator Console
2. Update Rollup 4 for the VMM Server
Let’s start. First, check if the VMM DHCP agent version is up date, as you will need to manually remove it before installing the new one:
From an elevated PowerShell Command Prompt window on the hyper-v host:
PS: >Get-WmiObject -Class win32_product -Filter ‘Name = “Microsoft System Center Virtual Machine Manager DHCP Server (x64)”‘
If result version is earlier than 3.2.7768.0, you will firstly uninstall the old version:
PS: >MsiExec.exe /X <IdentifyingNumber>
Note: <IdentifyingNumber> information should be retrieved from the output of the last command: Get-WmiObject
Locate and copy the file Dhcpextn.msi and run it on each hyper-v host (follow the steps in the wizard)
Note: By default, this is C:\Program Files\Microsoft System Center 2012 R2\Virtual Machine Manager\SwExtn\DHCPExtn.msi.
Double-click the DHCPExtn.msi to start the installation, and then follow the steps in the wizard.
Between these two installations, VMM Server might create one critical error log under the VMMLogs directory. This occurs because AdminConsole shares some DLLs with VMMServer, and version conflict could lead to the logging of the critical failure. To resolve this issue, install both of the updates on the VMM server that you use to start the VMM service.
A fellow MVP Andy Syrewicze and Eric Siron wrote a Hyper-V Security book. the book is a guide on how to defend your virtual environment from attack.
The book covers securing the Hyper- Hosts, the Virtual Machines, the Network and the Storage as well as how VMM in play changes the security approach.
