Hyper-V Host Patching – Cluster Aware Updading vs. Virtual Machine Manager Fabric Patching

Windows Server 2012 Logo

In the past weeks I was giving a Windows Server 2012 Hyper-V workshop to customers and as we went to the Hyper-V host management I talked about how you can update your Hyper-V infrastructure and how you can automatically update your Hyper-V cluster.

If we do not think about System Center Orchestrator we have basically two solutions to fully upgrade our Hyper-V clusters first is the System Center Virtual Machine Manager Fabric Patching which is available since System Center 2012. The second one is a new one called Cluster Aware Updating which is included in Windows Server 2012.

Both solutions do basically the same thing and using the same concept:

  1. Scanning the Hyper-V host for updates
  2. Putting the first node in maintenance mode and pause the node in the cluster
  3. Moving all virtual machines to other nodes of the cluster
  4. Installing the patches
  5. rebooting the server
  6. checking if all services are up again
  7. stop the maintenance mode
  8. start doing the same with the next node

This is basically what both solutions are doing, but there are small differences between them and both have advantages and disadvantages.

Cluster Aware Updating (CAU)

  • Moving not only virtual machines to other nodes, it does also move other cluster roles and cluster disks to other nodes
  • Cluster Aware Updating can use different update sources (Windows Update, Microsoft Update, WSUS, SCCM,…)
  • You can apply hotfixes via CAU
  • Cluster Aware Updating has APIs for third party vendors
  • You can do driver or firmware updates via CAU
  • You can schedule it via Self-Updating mode
  • Run pre- and post-scripts
  • Update Approval process over WSUS or SCCM
  • Only supporting Windows Server 2012
  • Coordination via cluster role

System Center Virtual Machine Manager

  • Does only move virtual machines to other nodes
  • Needs a WSUS server where the updates come from
  • Only updates which can be installed via WSUS
  • Virtualization (Fabric) Administrator will create update baselines and approve updates
  • Not third-party integration
  • Log – logs which administrator approved the updates
  • Integration in System Center Operations Manager, sets host in maintenance mode on SCOM so no alerts are generated.
  • Role based update management
  • Supports Windows Server 2008, Windows Server 2008 R2 and Windows Server 2012 Hyper-V.
  • Coordination via Virtual Machine Manager

Both solution do a great job and can of course be extended by using Windows PowerShell, System Center Orchestrator or third-party products.

The two main differences are Windows Server 2012 Cluster Aware Updating is definitely the newer solution with extensibility for third-party solutions with support for other cluster roles not just Hyper-V. Where System Center Virtual Machine is the clear winner, is where you have security roles in place and you need logs and other security features. And System Center Virtual Machine Manager has also a connection to System Center Operations Manager which lets you set Hyper-V nodes to maintenance mode.

Windows Server 2012 Hyper-V: Configure VM Processor Compatibility for Legacy Operating Systems

Windows Server 2012 Logo

In Windows Server 2008 R2 you had a setting in the Hyper-V Manager GUI to enable Processor Compatibility for legacy operating systems such as Windows NT 4.0 Server or Windows Server 2000. In Windows Server 2012 Hyper-V this setting is gone from the GUI, but you can still change it via Windows PowerShell.

By using the Get-VMProcessor cmdlet you can list the virtual CPU information of your Hyper-V virtual machines.

Hyper-V Get-VMProcessor

As you can see you can find a property called CompatibilityForOlderOperatingSystemsEnabled which is set to “False” by default and this is okay in 99% of all cases. But even if Windows NT 4.0 Server or Windows Server 2000 is not officially supported by Microsoft anymore there are some customers which have to run some VMs with legacy operating systems and by changing this setting via Windows PowerShell and the Set-VMProcessor cmdlet you can allow VMs to run old operating systems.


Set-VMProcessor NT4VM -CompatibilityForOlderOperatingSystemsEnabled 1

And of course you can also change it back


Set-VMProcessor NT4VM -CompatibilityForOlderOperatingSystemsEnabled 0

Virtual Machine Backup and Recovery: Five Critical Decisions

Virtual Machine Backup and Recovery

Together with Symantec, Mahmoud Magdy (Microsoft MVP for Exchange Server) and Mikko Nykyri (VMware vExpert) we produced a whitepaper called “Virtual Machine Backup and Recovery: Five Critical Decisions”. This whitepaper covers an overview about virtualization and the challenges which come with the new workloads in terms of backup and recovery.

Because of the outstanding economy, flexibility, and service levels it offers, virtualization is  transforming data centers at breakneck speed: by 2016, an estimated 80 percent of the world’s x86 servers will be virtual machines (VMs).1 But the speed of this transformation, along with  the high resource utilization, ease of cloning,  moving workloads, and other ways virtualization  works its magic, raise challenges for “traditional” IT services and the teams that deliver them. Nowhere is the complexity that virtualization creates for traditional IT services more apparent than in backup and recovery, which participants in a recent Symantec survey ranked among their least-successful IT initiatives. This paper addresses five critical decisions organizations  must make when building a backup and recovery plan to:

  • Maintain protection, visibility, and control of applications  and data.
  • Maximize utilization of established infrastructure,  processes, staff, and budget.
  • Use virtualization to improve backup and recovery processes.
  • Create an efficient, scalable, future-prepared backup and recovery environment.

Each issue is presented first in general terms that apply across IT environments, and then add comments for specific platforms, applications, or industries based on our individual experience as VMware® vExperts and Microsoft® MVPs.

You can download the whitepaper here: Symantec Virtual Machine Backup and Recovery: Five Critical Decisions

Make also sure you checkout the Google Hangout event on Fri, May 10, 7:00 PM – 8:00 PM.

Join a panel of virtualization experts including Microsoft MVPs Mahmoud Magdy & Thomas Mauer and VMware vExpert Mikko Nykyri as they discuss the white paper they co-authored and offer their thoughts on the most important things to consider for a virtualized server environment.

How to install System Center 2012 SP1 Update Rollup 2 for VMM

System Center Logo

Microsoft last week released the Update Rollup 2 for System Center 2012 SP1 – Virtual Machine Manager which includes a lot of fixes and improvements. If you want to update you can do this by using the Windows Update scenario or install it manually.

You have to uninstall the Update Rollup 1 for SCVMM (you can find more on the reason on Carmen Summers blog post). Windows Update will not show you the Update Rollup to before you have uninstalled UR1.

If you have downloaded the Update Rollup 2 via the Windows Update Catalog and have installed it manually, it’s recommended that you uninstall UR2 first, after that uninstall UR1 and finally install UR2 on a System Center 2012 SP1 installation without any Update Rollups installed.

SCVMM Agent Update

After you have installed the Update Rollup 2 for Virtual Machine Manager, make sure you also update the Agents on the Hyper-V hosts.

VMM Agent Versions:

Update Rollup 1: 3.1.6011.0
Update Rollup 2: 3.1.6020.0

SCVMM Agent Version

Btw. Remember to do this not only for the VMM management server, don’t forget the hosts where the VMM console is installed, like System Center App Controller.

Two months with the Surface Pro and how it replaced my notebook

Swiss Microsoft Surface Event

At the Microsoft MVP Summit back in February I had the chance to get a brand new Microsoft Surface Pro, after I already used a Surface RT which a had since November 2012. I already wrote a very small review a few days after I got it in the Microsoft Store in Bellevue WA and used it during the MVP Summit.

Since I am back from Redmond I am using my Surface Pro for work when I am on the road, at customers, working at the office, at university, at hotels or at home when I am working in the living room. Basically the Surface is my daily companion. At home and for long flights I still use the Surface RT because it’s lighter, has better battery life and it because of it size and weight it feels more like a tablet.

And here are my impressions after I used it now for two months.

Microsoft Surface Pro

Hardware quality – The build quality of the hardware is just amazing. As the Surface RT the Surface Pro is just high quality hardware. Even after 2 months this piece of hardware still looks great and elegant. There is nothing broken or anything else which I am unhappy about. I really like to work with great devices that’s was one of the reasons I used Apple products some years ago and I still think Microsoft is maybe the only one who can keep up with the quality of Apple hardware, because most of the other OEM’s do not get it right.

Microsoft Surface Pro

Amazing display – The screen of the Surface Pro is great with a good contrast and great colors like the Surface RT but with a Full HD resolution. I am really happy with the Full HD resolution, especially when I am working with System Center products or I am taking notes with OneNote.
I am using my Lenovo ThinkPad X1 for lab installations and testing, and the screen is terrible if you compare it to the Surface Screen. The only problem I had with the Surface Pro is that it’s hard to sit in front of a 10.6” screen for like 8-10 hours. At the office I don’t have this problem because I can use a external monitor and most of the customers I work for are doing the same, so this isn’t a big issue.

Surface Pro

Digital Ink – The Surface Pro comes with a digitizer pen which is perfect to take notes with OneNote and other stuff. As I mentioned I am using the Surface Pro at work and at university. At university I am using the pen mostly to take notes and mark some important stuff in documents. At work I am not only using it to take notes, it’s also great during workshops or presentation, where you quickly want to draw something instead of using a whiteboard or a flipchart.

Surface

Performance – The Surface Pro is equipped with a Intel Core i5 processor and 4GB of RAM which brings really good performance. Well I cannot really talk about performance because normally you only talk about performance when you don’t have enough, but I never had any performance issues with the Surface Pro and I even think the performance is better than the notebooks I used before.

Microsoft Surface Pro

Features – Well many people already know about features like the kickstand or the Touch and the Typecover, which is by the way pretty good to write on and I am used to use a ThinkPad which has an amazing keyboard. Another cool and useful feature is the build in USB charging port in the power adapter, which lets you charge another phone even if the Surface USB port is already used by another device.

surfacespecsheet

Size and weight – The Surface Pro is not much thicker and heavier than the Surface RT but if you compare them site by site it’s a big difference. Even my Lenovo ThinkPad X1 was a very light and small business ultrabook, the Surface Pro feels a lot lighter and needs a lot less space and is much easier to carry it around.

Battery life – Same as the size the battery life is not like it would be on a normal tablet. I got in my tests 4-5 hours of battery life, when I am working 100% on my Surface Pro. During time at university I get around 6 hours which is enough for one day. During long flights it does not really make sense to use the Surface Pro because the only thing I need there is Office 2013, to work on presentations and documents, a video player to watch movies and of course a lot of battery life to do all this things. The Surface RT is much more suitable for this scenario.

Surface Typecover Touchcover

Accessories – If you want to replace your notebook with the Surface Pro you may need three things, except the Type- or Touchcover. First you need a adapter for VGA or HDMI output so you can connect a projector or external monitor. The Surface Pro has a Mini-DisplayPort output and offers two adapters, one for HDMI and one for VGA, but you can also use adapters from other vendors.

The second thing you need is a USB to Ethernet adapter, because most of the enterprise customers do not offer Wifi access to their network and business users basically need a Ethernet port. The downside of using such a adapter is that you loose the only USB port and this can be a problem if you want to use a USB drive or a external disk at the same time. Microsoft offers also a USB to Ethernet adapter but like for the display adapter you can also use other adapters.

The last thing you need is a mouse, even you have a touchscreen and a trackpad, there are a lot of thing which are much more efficient with a mouse. I use the Microsoft Wedge Touch Mouse Surface Edition which is small and perfect if you travel.

Software – Windows 8 is the perfect mix from desktop and tablet OS. For a lot of people the mix of two different UIs is something bad, for me its just the best solution because the OS offers me the best from both worlds. I am also a huge fan of the Microsoft Account integration which syncs settings from all your devices.

SkyDrive and SkyDrive Pro make my life a lot easier, I don’t really have to copy files between different devices because they are available everywhere and get synced automatically. And Office 2013 or Office 365 Home Premium integrated perfectly in this scenarios and you get 20GB of extra SkyDrive storage.

The Xbox integration with the Xbox Smart Glass technology is just perfect, if you are sharing media in the living room or watch movies or listen to music it’s the a great Xbox companion.

Conclusion – Well after two months I don’t carry my notebook anymore, the Surface Pro totally replaced it not only because it is much smaller and lighter, not it only because of the additional features I get with the Surface, for example the Touchscreen, the tablet form factor and the digitizer pen.

My wish list for the next Pro version would be:

  • Make it thinner and lighter like the Surface RT would be great
  • Longer battery life - I know it’s hard to get performance and battery life at the same time, but 8-10 hours of battery life would be just awesome.
  • Different sizes - This is maybe not just about the Pro version, but maybe for the whole Surface series. A smaller Surface around 7” would be great for doing some small tasks. The other thing I thought about would be a 11” or 12” Surface which would be even better, if you use it as a notebook replacement.
  • USB ports - A second USB port or a passive USB hub, which would not need extra power but fix my problems.
  • More cool accessories – In todays tablet world it’s hard to be different. One thing is the OS and the other one are the accessories. Microsoft did a great thing with the kickstand and the Touchcover but I pretty sure that there is more in the Microsoft labs.
  • Availability – Well make them available outside of the US ;-)

What would you be on your wish list?

Update:

Microsoft announced yester day that they will expand the Surface Pro and Surface RT availability. Surface Pro will launch before the end of May in Australia, Austria, Belgium, Denmark, Finland, France, Germany, Hong Kong, Ireland, Italy, Luxembourg, New Zealand, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom. Surface Pro will launch in Korea, Malaysia, Russia, Singapore, and Thailand before the end of June. Surface Pro is currently available in the U.S., Canada, and China. Thanks to Bjorn for the link.
