MMS Midwest Management Summit

Speaking at MMS

After System Center Universe Europe 2014 and E2EVC Brussels, I am proud to announce that I am also speaking at the new Midwest Management Summit (MMS). The Midwest Management Summit is a 3-day conference purposely capped to just 500 attendees so that nobody gets lost in the crowd. Speakers have time to meet and talk to you. No rushing people out of a session to get the next speaker going. Time to absorb what you see and talk it over with speakers and other attendees.

I will speak in two sessions:

Building a Datacenter Abstraction Layer with Virtual Machine Manager

The session delivers an overview about how you can build a Datacenter Abstraction Layer between your Fabric such as Storage, Network and Compute resources and your services. The session is focused on Fabric Management with System Center 2012 R2 Virtual Machine Manager. Attendees will learn how to build an Datacenter Abstraction Layer between Fabric and Services with Virtual Machine Manager.

Disaster Recovery with Azure Site Recovery

The session shows you, how you can use Microsoft Disaster Recovery Technologies such as Hyper-V Replica, System Center Virtual Machine Manager and Azure Site Recovery to failover your Microsoft Cloud. It also shows the scenario how you can replicate virtual machines to Microsoft Azure. This includes knowledge about the different Disaster Recovery Solutions from Microsoft

The Midwest Management Summit will take place from November 10-12 in the Radisson Blu, Mall of America Minnesota, USA.

If you are interested to join the so called new MMS, checkout the  Midwest Management Summit website.

Join the Midwest Management Summit and learn everything about the Microsoft CloudOS, System Center, Hyper-V, Microsoft Intune and Microsoft Azure.



E2EVC Copenhagen

Speaking at E2EVC 2014 Barcelona

This year I was already speaking at the E2E Virtualization Conference in Brussels. Together with Michael Rüefli I was talking about the Microsoft CloudOS and how you can build a Cloud based on this technology such as Windows Server, Hyper-V, Storage Spaces and Windows Azure Pack.

From 24-26 October the E2EVC will take place in Barcelona, Spain. In one session I will speak about Disaster Recovery with Hyper-V Replica and Microsoft Azure Site Recovery Manager. I will show you how you can failover your Virtual environment from one datacenter to another or how you can failover your Virtual Machines to Microsoft Azure.

Best Practices for running Linux on Hyper-V

Sometimes I just need my blog as a reminder or a database to find something in a few months so this is exactly one of this blog posts. Microsoft has a TechNet article where they describe the best practices for Linux VMs running on Hyper-V 2012 or Hyper-V 2012 R2. The article is a list of recommendations for running Linux virtual machine on Hyper-V.

Right now they have 4 recommendations on the list (Source Microsoft TechNet):

  • Use static MAC addresses with failover clustering.
  • Use Hyper-V-specific network adapters, not the legacy network adapter.
  • Use I/O scheduler NOOP for better disk I/O performance.
  • Add “numa=off” if the Linux virtual machine has more than 7 virtual processors or more than 30 GB RAM.

SCVMM 2012 R2 Error 23317 When You Try to Apply Changes on VM That is Using Shared VHDX Disk

A customer of mine had a issue when he tried to change properties of Virtual Machines in System Center Virtual Machine Manager 2012 R2 which use shared VHDX, which were not created with VMM. The properties do he wanted to change had nothing to do with the Shared VHDX it self. He tried to set the availability set for these Virtual Machines.

The Error in SCVMM is the following:

Error (23317)
The operation Change properties of virtual machine is not permitted on a virtual machine that has shared virtual hard disks.

Recommended Action
The operation Change properties of virtual machine is not permitted on a virtual machine that has shared virtual hard disks.

Stanislav Zhelyazkov (Microsoft MVP) blogged about this in October 2013. The solution is pretty easy and is called PowerShell. Just do the modification but do not apply it. Use the script view in Virtual Machine Manager to get the code which would run behind the scene.

For example:

Remove all the things you don’t need and run the script:



Windows Azure Pack IaaS

Update Rollup 3 for Windows Azure Pack available

Microsoft released the Update Rollup 3 for System Center 2012 R2 with a lot of fixes for several product such as Virtual Machine Manager, Data Protection Manager or Orchestrator. This updates to directly affect private cloud deployments and public cloud deployments by service providers by bringing new functionally to the solutions. With that Microsoft also released Update Rollup 3 for Windows Azure Pack which also brings fixes and enhancements.

  • For stand-alone virtual machines (VMs) whose templates specified multiple network adapters, the tenant user cannot associate a particular network to each network adapter.Symptom: If the user is creating a VM that’s based on a template that contains multiple network adapters, the Tenant Site VM extension will automatically assign the first available network.

    Resolution: The tenant user now has the necessary user interface (UI) to select a particular network for a particular network adapter.

  • Developers who use Web Site Cloud to deploy PHP applications do not have an option to specify PHP 5.5 version.Symptom: If the user wants to deploy a PHP 5.5 application, there is no option to specify that version of PHP.

    Resolution: The user now has the PHP 5.5 version option.

  • Usage records that contain more than 4,000 characters of resource data are not supported.Symptom: If the Usage Collector encounters a usage record that has more than 4,000 characters, it fails and shuts down the usage pipeline for System Center usage data.

    Resolution: Some of the instructions in this article involve running an SQL script that will increase the size of the table field to nvarchar(max).

  • Tenants experience unexpected behavior in the portal when they create websites that have the same name in different plan subscriptions that are each on a separate Web Site cloud.Symptom: When a tenant creates two websites that have the same name on different Web Site clouds and subscriptions, the portal may display inaccurate information about one or both of the websites.

    Resolution: Users can now create websites that have the same name through separate subscriptions and clouds without seeing incorrect information about their sites or subscriptions.

  • Tenants who create an ASP.NET site by using Web Site Cloud cannot specify whether the Application Pool will be running in Classic or Integrated Mode.Symptom: When a tenant tries to create a website, the user notices that the Application Mode setting is not available. If the application requires Classic Mode, it will run the risk of failing at run time.

    Resolution: Users can now specify the Application Pool mode for their applications.

  • Administrators cannot use Fully Qualified Domain Names (FQDN) when they configure SQL Always-On Listeners, because the Windows Azure Pack Resource Provider for SQL Server does not support it.Symptom: When an administrator enters an FQDN in the SQL Extension of the Administration site, the SQL Resource Provider accepts it, but an error is returned after the provider tries to process the FQDN.

    Resolution: FQDNs are now fully supported by the Resource Provider.

  • When a tenant creates a VM, the name that is provided is not honored. Instead, a name is generated.Symptom: When tenants build a VM on premises, they expect the name that they provided to be honored as the NetBIOS name of the computer. This is not the case; the VM extension generates a name to maintain uniqueness in System Center Virtual Machine Manager.

    Resolution: Now the VM Resource Provider generates a name that’s based on the name that the user provides in the following pattern:

    Computer Name = name + “###”

    The numbers are added to the end of the name to guarantee uniqueness in System Center Virtual Machine Manager.

  • The metrics that are associated with websites that are located in separate clouds whose endpoint credentials differ from each other are sometimes not retrieved; instead an error message is displayed.Symptom: When the tenant or administrator accesses information about websites that are located in clouds that are configured to use different endpoint access credentials, you receive the following error message from the Administration site:
    The server could not retrieve metrics (Internal Server Error).

    Resolution: The monitoring service responsible for retrieving the websites data now returns the correct metrics instead of an error.

  • The SQL Resource Provider grants DB Owner permissions to tenants when during database provisioning.Symptom: When a SQL Server Database is provisioned by a tenant, the SQL Resource Provider grants DB Owner permissions to the corresponding SQL login.

    Resolution: Tenant logins that are created after you apply Update Rollup 3 are no longer granted DB Owner permissions. Existing tenant logins and already existing databases are not affected. To retroactively give existing tenant logins the same set of permissions and to remove the DB Owner level access, see the following TechNet article:

  • SQL Server Integrated Security or Windows Authentication is not supported by the Windows Azure Pack Tenant Site SQL extension.Symptom: When the tenant tries to create a database, no option for Windows Authentication is provided.

    Resolution: The SQL Tenant Site Extension now supports Windows Authentication.

RemoteFX

GPU Requirements for RemoteFX on Windows Server 2012 R2

If your are planning a VDI (Virtual Desktop Infrastructure) deployment with Windows Server 2012 R2 Hyper-V  and you want to use physical graphics power with RemoteFX for your VDI machines fore example for CAD applications, you might wonder which cards are recommended and supported. Back in November 2013 Derrick Isoka (Microsoft Program Manager) wrote a blog post about recommendations and here is a quick summary.

RemoteFX GPU Requirements

To make use of RemoteFX with GPU acceleration on Windows Server 2012 R2 you require a compatible graphic card.

Most likely, the servers hosting the RemoteFX workloads will be located in a datacenter and as such, we recommend using passively cooled, server class graphics cards. However, it’s also acceptable to use a workstation card for testing on small deployments depending on your needs.

However the minimum requirements for the graphics cards to be used with Hyper-V RemoteFX are:

  • Direct 11.0 or later
  • WDDM 1.2 driver or later

DirectX and WDDM

There is some other point to this, in Windows Server 2012 R2 provides support for DirectX 11.0, DirectCompute and C++ AMP. Most of the graphics cards do support OpenGL 4.0 and OpenCL 1.1 or later, however these APIs are currently unsupported by RemoteFX in Windows Server 2012 R2.

Hardware and Driver Support

To find a graphics card also make sure you check the Windows Server Catalog.

RemoteFX Compatible GPUs

Microsoft did some tests and showed some of the results on the Remote Desktop Services blog.

RemoteFX Cards

  1. Best: These are server class cards, designed and certified for VDI workloads by hardware vendors like NVIDIA and AMD. They target the best application performance, experience, and virtual machine densities. Some of the cards are particularly recommended for designer and engineering workloads (such as Autodesk Inventor or AutoCad).
  2. Better: These are workstation class cards that provide acceptable performance and densities. They are especially capable cards for knowledge worker workloads (such as Microsoft Office or Internet Explorer).
  3. Good: These are lower-end cards that provide acceptable densities knowledge worker workloads.

Performance and Scale

This is important, Microsoft also points out that GPU speed and memory, the performance and scale of your VDI deployment also depends on additional factors such as CPU, Storage and Network performance.
