Windows Server 2012, Performance, Features and Virtualisation –Xmas Reading

Posted on : 31-12-2012 | By : DamianD | In : Microsoft Virtualisation, WS2012

As 2013 knocks on the door its seems to me more likely than not that Windows Server 2012 will start getting some customer traction, and the number of pilots and POCs will rise.

I’m fairly comfortable with all that Windows Server 2008 R2 SP1 has to offer, and this is especially true of Hyper-V 2 as its not officially known.

WS2012 and Hyper-V 3 is a different fish kettle. I’ve been to marketing events and looked at highlight details but not got under the bonnet (that’s “hood” for you Americans Smile )

To that end i’ve found some reading material that will start me off, and may be of interest. Its not an ordered selection, just some interesting starter for 10’s that i will flesh out over time.

First up – Introducing Windows Server 2012 – A brief overview of 2012 and its new features.

Next – A more detailed overview of the specific virtualisation features in WS2012

Next – Performance Tuning Information to consider for WS2012

And finally, a reference document discussing the application compatibility support provided by WS2012. Happy Reading !

Problem with WinRM on a Hyper-V Server Core install

Hot off the press from being shown how to resolve this issue by top techie Gareth Evans ( @gareth78 Basically the issue seems to occur if you are running Windows 2008 Server core, with the firewall offline, and decide to update the SCVMM agent on the host server.  The result is a peculiar fault with WinRM which results in a lack of WinRS connectivity and a big fat error from Server Manager. See below. image and from WinRS (winrs –r: server name <command>) image The fault occurs because the WinRM configuration seems to be reset after the VMM agent upgrade (just a hypothesis!) It leaves the server without WinRM listening on port 5985. To resolve on a server core build you need to do the following steps:-
  1. Set the firewall service to demand
  2. Stop VMM agent
  3. Start firewall service
  4. Stop WinRM service
  5. Start WinRM service
  6. Set firewall service back to disabled if this is how you had the configuration
  7. Start VMM agent
You should then get both 80 and legacy port 5985 enabled.. run the command winrm /e winrm/config/listener to check this. image Happy days! In script friendly style this is:- sc config  mpssvc start= demand net stop vmmagent net start mpssvc net stop winrm net start winrm net stop mpssvc sc config  mpssvc start= disabled net start vmmagent Note: In SCVMM you will see a warning against the hosts and the hosted virtual machines will be listed with a blue i icon rather than the usual play or stopped icons. This will clear once the VMM refresh completes. More useful WinRM info is available in this blog. Jonathans Virtual Blog Late update -you may need to disable and re-enable winrm rather than just restart the service to enable the 5985 port. I used Core Configurator for this ….

Tech-ed session with Ben Armstrong

http://www.msteched.com/2010/NorthAmerica/VIR304

 

Dynamic memory is a new feature of Hyper-V coming to Windows Server 2008 R2 SP1. Come to learn how Dynamic Memory enables Hyper-V to more efficiently utilize system resource, and how this can benefit your environment. Also learn how Dynamic Memory works under the covers and what you should be preparing for with the release of Windows Server 2008 R2 SP1.

 

Interesting demo + description of how dynamic memory is not equal to memory overcommitment in ESX.

 

Also discussion on page sharing and large page sizes.
