Microsoft Azure Stack Announcement

From Azure Announcement blog


“Microsoft is the only cloud vendor that builds and runs its own hyper-scale datacenters and delivers that technology back to customers. We are infusing our experience into our hybrid cloud technology through battle-hardened cloud infrastructure and integration of Azure design points for greater consistency between Azure and customers’ datacenters. We are bringing the next wave of this innovation to our customers with Microsoft Azure Stack.

Built on the same core technology as Azure, Microsoft Azure Stack designed to bring Azure to your datacenter for the deployment of enterprise and modern applications at any scale. Azure Stack enables IT professionals to transition from traditional IT control methods to providing users and developers access the tools they need when they need them, while still maintaining central control.

  • Empowering users and developers with a consistent, self-service cloud experience: Azure Stack brings the ease of cloud application deployment to the on-premises datacenter, supporting the same experience as Azure with Azure Resource Manager (ARM) templates (made available in preview last week at BUILD). ARM templates provide a gateway through the Azure portal for seamless service delivery across Azure and datacenters, reducing friction in the hybrid environment. Users can deploy workloads to Azure or on-premises based on business requirements, focusing on the application itself rather than the infrastructure. Azure Stack enables access to many of the same Azure IaaS and PaaS services on-premises, with the same intuitive self-service experience they would have with Azure. Azure Stack also empowers developers to innovate faster and on their terms by providing access to the broadest set of development tools and platforms.
  • Improving flexibility with cloud-inspired software defined infrastructure: Azure Stack extends Microsoft’s investments in the software-defined datacenter across compute, software-defined storage, software-defined networking, and software-defined security. These innovations provide a flexible and more secure datacenter architecture
  • Speeding time to value with simplified deployment: The deployment and configuration of private and hybrid clouds can be daunting and resource-intensive. Azure Stack will offer a simplified deployment and configuration experience.

Customers will be able to take advantage of the first Azure Stack features in preview this summer.  For more information, visit”

Theme Night focusing on Hybrid Identity & Business Continuity

It is a great time for big Microsoft events. We’ve just closed the door on Build 2015 in Los Angeles. Today the colossal new event Microsoft Ignite is about to open its doors and soon we’ll have the local Microsoft TechDays. We are seeing fantastic developments around Azure, Windows Server, Windows 10, Open Windows Platform, Continuum and Hololens. We may even get a glimpse of the new Azure Pack.

The SCUG NL & user groups offer you to follow these developments closer to home. Just before Techdays 2015, we organize our second Theme Night called:

“Azure to the rescue: Hybrid Identity & Business Continuity”


In this second edition of Theme Night, Simon May and Sergio Pattinama will talk about Hybrid Identity, Windows 10 and Business Continuity/Disaster Recovery based on Azure Site Recovery (ASR). Simon will dive into the world of Hybrid Identity. How to you connect your on-premises Active Directory and Azure Active Directory and why this is an important part of Microsoft Online Cloud Services such as Azure, Office 365 and Microsoft Intune. Next Sergio Pattinama will show how to set up Azure Site Recovery to make DR scenarios easily accessible for customers with Hyper-V, VMware and even physical servers. Replication to your own second datacenter, a hosting provider datacenter or the Azure datacenter are possible targets for ASR. In the third and final presentation, Simon May will talk about enterprise mobility with Windows 10.


May 27, 2015


  • 16:30 – 17:00: Reception
  • 17:00 – 18:00: Diner/Buffet
  • 18:00 – 19:00: Hybrid Identity – Simon May
  • 19:00 – 19:15: Break
  • 19:15 – 20:15: Business Continuity – Sergio Pattinama
  • 20:15 – 20:30: Break

What are “Theme Nights” ?

During these events we keep you up-to-date with topics regarding Azure, Hyper-V & System Center!  Developments in IT-land go so fast that it is very hard to only touch the surface of these subjects. We choose a Theme Night to go deeper on the individual topics and hope to give you a deep understanding of a particular topic. We try to get (international) renowned speakers, often MVP in the field.

Free ticket to Techdays 2015

During this “Theme Night” we’ll raffle a free ticket to TechDays 2015! The Dutch event will be on May 28-29, a top-event with 150 sessions you really shouldn’t miss.

Of course we close with a food and drinks.

Nested Hypervisor in Windows Server vNext

In his presentation at Build 2015 on Windows and Hyper-V Containers, Taylor Brown almost casually mentioned that in the next version of Windows Server, it will be possible to enable Hyper-V in a Hyper-V VM. The news was broken by fellow Hyper-V MVP Ronald Beekelaar who attended this great session in San Francisco.

Very quickly dozens of emails appeared in my mailbox from very enthusiastic fellow MVPs who have been begging for this feature for several years now. In fact I have also pleaded for nested hypervisor as we often have to build labs and prepare demos which include Windows Azure Pack. Some of its features can do without a Hyper-V server or cluster such as websites, databases, service management automation, but if VMM and infrastructure as a service is involved, we badly miss a Hyper-V host to deploy VM Roles. Of course we could add physical host to the lab, but with so many consultants in our CloudOS team, there just isn’t enough hardware.

Now that Microsoft has acknowledged that nested Hyper-V will be possible in a future build of vNext, it will be much easier for us to start learning the new Azure Pack and the many new features of Virtual Machines v2, equivalent to public Azure that is on the roadmap.

The real reason why Microsoft introduces running Hyper-V within Hyper-V is the anticipated new service to run Hyper-V Containers in Azure. Just like hypervisors abstract the operating system from the hardware, containers abstract the application from the operating system. There are two types of containers: Windows Server Containers and Hyper-V Containers. The former runs on the bare metal and the latter requires the Hyper-V hypervisor so that Containers can run in Hyper-V VMs. It stands to reason that Hyper-V Containers are much more suitable for Azure than giving customers access to the physical host, which would simply be impossible.

So expect to be running Hyper-V containers in an Azure VM (probably of the Nano Server type), running on the Azure fabric and once this is possible, you will also be able to run other guests inside an Azure VM. Because the same version of CloudOS will be available to public Azure, hosted Azure as well as private Azure, you can benefit from this new technology wherever it suits you best.

I can hardly wait for this new technology to become generally available!

If you want to see the session on Containers by Taylor Brown and Mathew John, take a look at the slides and recorded presentation:


Azure Site Recovery with Hyper-V Generation 2 VM Support

The Azure team at Microsoft cannot be denied to run at a very high pace, when it comes to introducing new Azure functionality. Not only do public Azure features show up like clockwork every six weeks, this is also true for feature updates related to Hyper-V and System Center in the private cloud which get updated at an incredible pace. Just a few weeks ago we had to tell customers that if they had boot drives larger than 127GB, more than 1 network adapter, fixed IP address or when they had already adopted Hyper-V Generation 2 VMs, Azure Site Recovery would be a no-go (yet). But customers of the Azure cloud never have to wait very long and they get a very large say in what features are most important for them. Just take a look at the User Voice for Azure Site Recovery:

This week I was lucky to get a time slot from the Azure team to actually test the new Hyper-V Generation 2 support in our closest Azure datacenter West Europe, here in Amsterdam. I had already set up ASR as a preparation for several customers who were planning for Disaster Recovery from their onsite datacenters to Azure. I had more or less been ignoring the product as I didn’t have any use cases or the resources to test. But with interested customers, things can change very quickly. So I quickly configured a small research environment with one Hyper-V host, a few Generation 1 and 2 VMs, SQL Server 2014 and Virtual Machine Manager 2012 R2 with Update Rollup 5.

I will not detail the complete setup and configuration as this has already been well documented. Be careful not to read blogs on ASR older than a couple of months as so much has changed. In this blog I will focus on the new support for Hyper-V  Generation 2 VMs. Generation 2 VMs arrived with Windows Server 2012 R2 Hyper-V and made installing VMs a little faster because none of the ancient devices had to be discovered. Also with the replacement of the VM BIOS by a UEFI, several new features became available:

  • Secure boot
  • DVD Drive hot add/removal
  • PXE boot from synthetic network adapter

So let’s go back to the configuration of ASR for Generation 2 VMs. There are now multiple scenarios for ASR and my configuration is based on “Between an on-premises VMM site and Azure“, but there are several others available, including VMM site to VMM Site (with or without SAN Replication), Hyper-V to Azure (without VMM) or VMware Site to VMware Site (with or without SAN Replication), and we can expect a direct VMware to Azure before long. Because I had configured ASR some time ago, I had to download an update for my registration key. Secondly I had to refresh both the VMM ASR Provider and the Hyper-V ASR Agent for the Hyper-V host. If I had a 7-year old child, I could have delegated this task.

The major steps for protecting VMs with ASR are:

  • Setup
  • Configure
  • Protect
  • Author Recovery Plan
  • Disaster Recovery Drill


Presentations Theme Night “Hybrid Cloud”


Last week SCUG.NL and organized their first coordinated Theme Night focusing on “Hybrid Cloud” hosted by Ordina. The turnout was great with about 100 attendees who enjoyed their afternoon and evening with interesting content focusing on several Hybrid Cloud topics. Ben Gelens, Mark Scholman and Darryl van der Peijl gave in depth presentations about deploying VM Role with Desired State Configuration (DSC), Hyper-V Network Virtualization and Site2Site VPN Gateways between on-premise and Azure.

If you’d like to take another look at their presentation slides, you can download them here.

Update Emulex VMQ Issue: They finally did it!

Another update from the VMQ front, this time with the formal announcement of a declaration of peace.

After a very long struggle – which started in November 2013, not long after the release of Windows Server 2012 R2 – I dare now confirm that VMQ can be re-enabled on Windows 2012 R2 Hyper-V hosts with HP/Emulex 554FLB host bus adapters.


If you have followed along, you will know that we have published several blogs on discussing the matter. We initially discovered the problem in our own lab environment, then explained how to avoid the network disconnections by disabling VMQ, followed by how we tested the numerous HP/Emulex firmware and driver updates and about our interactions with Microsoft, Emulex and to a lesser extent HP. Many customers who were using the HP/Emulex, but also many other using OEM versions, were badly hit by the networking problems.  The problem with VMQ became well known all over the world, not to say notoriously known.

Several weeks ago I was able to test a combination of new HP/Emulex firmware and drivers (February 2015), combined with a private Microsoft hotfix (The KB for the final hotfix is KB3031598), provided by the Microsoft Networking team in Redmond. We already saw promising results using older versions, but there were a couple of remaining issues which had to be solved in the Windows NIC Teaming (LBFO) stack. One issue that I kept seeing was that when there were more VMs running on a particular host in the cluster than there were VMQs available, things started to collapse. Not only were the additional VMs not getting a VMQ Queue, they would also not get assigned to the default VMQ Queue. Other VMs that were already assigned to a VMQ Queue, were disconnected and it took some time for this problem to settle and make connections possible again.

Using the latest firmware/drivers with the Microsoft LBFO hotfix solves that problem (amongst others).

It is time to say that we have the worst behind us.

Na het succes van de jaarlijkse “System Center Summer Night” zijn en de System Center User Group een nieuwe weg ingeslagen. SCUG.NL en slaan wederom de handen in één en organiseren gezamenlijk dit jaar meerdere “Theme Nights”. Tijdens deze bijeenkomsten praten wij jou bij over wat nieuw is binnen Azure, Hyper-V & System Center! De ontwikkelingen in IT-land gaan ontzettend hard, het wordt dan ook steeds moeilijker om alle facetten van Azure, Hyper-V & System Center in één avond te bespreken en daarnaast te blijven voldoen aan ieder zijn verwachting. Dus volgens ons is er maar één oplossing; “Theme Nights”.


Wat houden deze “Theme Nights” in?
Wij zorgen ervoor dat jullie in een paar uur helemaal bijgepraat worden door (internationale) topsprekers en MVP’s, binnen een bepaald thema. Ben jij een echte Service Manager liefhebber en interesseert Hyper-V je eigenlijk weinig, geen enkel probleem! Schrijf je in voor de Service Manager “Theme Night” en je zal geen live migration voorbij zien komen.
