Today the Hyper-v.nu team received some very cool stuff… They all received a very nice polo and a fleece jacket. A special word of thanks goes to PQR! PQR has sponsored the Hyper-v.nu team with these cool clothes.
The Hyper-v.nu team will wear these clothes during events so that you can recognize them very easily and make a chat with them if you like
It is also possible to buy a polo. A polo will cost around the € 40,= (exact price will depend on the total amount of polo’s we order). Shipping is not included in this price.
Our twittername @hypervnu is printed on the frontside.
And this is the flipside.
Greetings from the hyper-v.nu team: @hvredevoort @jaapwess @myhyperv @pnoorderijk
Besides the excellent information regarding SCVMM 2012 Beta on this blog here is some very usefull information if you are playing around with System Center Virtual Machine Manager 2012 Beta!
This download provides technical documentation for the Beta release of VMM 2012.
Another great resource for information is the Virtual Machine Manager 2012 Community Evaluation Program Application or the System Center Virtual Machine Manager (VMM) 2012 Beta Resource Page.
Installation of Data ONTAP Simulator in a Hyper-V guest (CentOS) and using an SMI-S provider to connect to SCVMM 2012
If you are a NetApp Customer or if you are an Advantage Partner (or if you have good friends among them) you can get access to the NetApp Data ONTAP Simulator. The reason why I wanted to try this out is to have an SMI-S compliant storage device which I could use in my System Center Virtual Machine Manager 2012 lab. As you may know Microsoft decided to use the SMI-S provider (SNIA Standard) to enable deep integration of storage arrays for Virtual Machine Manager 2012. I wrote a detailed blog about it here.
Getting the simulator was one thing, installing a Linux VM with Hyper-V Integration Components was another. Fortunately it was easy to find some good step-by step guidance by Yusuf Ozturk (1 and 2) and Michel Lücher (3)
Installing Hyper-V v2.1 IC’s Setting up a CentOS 5.6 Desktop installation on Hyper-V and mouse support – Part 2
Because I don’t expect everyone to be able to read German, I will translate the instructions here and blog about my findings.
By the way, I have a third challenge … I don’t know anything about NetApp either, so this blog really describes my first steps into the Linux and NetApp world. At least the Hyper-V and System Center world is familiar territory.
I will not go through steps 1 and 2 because if you exactly follow Yusuf’s steps, you will end up with a Hyper-V aware CentOS guest. I downloaded the DVD ISO for CentOS 5.6 here.
The Netapp Data ONTAP simulator can be downloaded here.
Update October 21st, 2011 (see bottom)
Let’s assume the following scenario:
- You have a Hyper-V R2 SP1 cluster that has three or more nodes
- You are using Cluster Shared Volumes
- You learnt about the Cluster Validation problem that was solved by KB2531907 back in May 2011, which prevented the “Failed to get SCSI page 83h VPD descriptors for cluster disk <number> from node <node name> status 2” error after running the Validate SCSI Vital Product Data. It also solved the “Disk with identifier <value> has a Persistent Reservation on it. The disk might be part of some other cluster. Removing the disk from validation set” error when running the List Potential Cluster Disks test. The hotfix resolves an issue in which the storage test incorrectly runs on disks that are online and not in the Available Storage group. The problem can also be caused by other issues such as storage problems or an incorrect configuration which means you have to check your storage configuration and check related events on your Hyper-V hosts.
- You want to add more capacity and add a new Hyper-V host.
When you look at the Hyper-V marketing page, you’ll notice that the list of supported operating systems is incomplete. If you want to know the whole support story including the recent CentOS Linux distribution that was added please go to the TechNet page, which also states end-of-support for some older Microsoft operating systems such as Windows Server 2000 with SP4 and Windows XP with SP2.
Here is the list for Linux distributions and as you can see they all have multi processor support up to the current maximum of Hyper-V R2.

When Sinofsky detailed the different teams that are building Windows 8, I noticed that Storage and File Systems are one and the same group. Beneath you see a list of the most important teams in my opinion that will leverage the Microsoft Private Cloud which is built around Hyper-V and System Center 2012. The release of Hyper-V version 3 in Windows Server 2012 or Server “8” as we still have to call it, will be the cream on the cake and will boost the Microsoft Private Cloud even further. What we have seen so far is much higher virtual CPU’s in guests and awesome Hyper-V Replication technology. Add to that a decent file system and new storage innovations, both in the host and in the guest, we are ready for primetime. What will happen to CSV? What will happen to the scalability of the Hyper-V cluster?
We will soon find out! The Build Windows 2011 developers conference will unveil what all these product teams have invented. I really can’t wait! Because the conference is sold out, I plan to reserve time for the live streams instead.
Thanks to everyone who participated in the Altaro contest. I selected @zetacipher as the winner of the unlimited license for Altaro Hyper-V Backup. I will send the license as soon as I receive it from Altaro. Congratulations @zetacipher.
I’d like to draw your attention to a survey focusing on why you selected Microsoft as your virtualization platform.
This survey aims to get an idea about why you chose Hyper-V, how you use it, and what your experience has been. It has nothing to do with Microsoft; they’ll see the results at the same time you do. And we’re not collecting any personal information.
There are 4 pages of questions. Yes; that might seem like a lot but you’ll get through this in a few minutes. When it is complete, we will be publishing the results and analysis on the following sites. We believe it should give everyone an interesting view on what is being done with Hyper-V worldwide.
You can find the survey here: http://kwiksurveys.com/online-survey.php?surveyID=NLMJNO_8579c98b

Today Altaro launched their new Hyper-V Backup product. As you can read in the review we wrote earlier, the virtual machine backup software includes support for Cluster Shared Volumes and the very useful Fire Drill feature. Altaro offers 3 editions including a freeware edition. Pricing can be found at the end of this page:
Altaro was kind enough to offer Hyper-V.nu a complimentary unlimited license for Altaro Hyper-V Backup which is worth $445
|Full Altaro Hyper-V Backup Give Away License
I am giving away a full license to the reader who retweets my announcement on Twitter and gets retweeted by the tweeter with the highest number of followers. You can tweet as much as you like.
Please send me an e-mail with a copy of this RT to hans [at] hyper-v.nu before Sunday the 14th 2011 noon CET
By all means, go to http://www.altaro.com/hyper-v-backup/ for more information on the product!
A couple of months ago @robakk asked me if I would co-operate with a Hyper-V video reference. Off course I said yes to this nice invite. On the 23rd of June I visited the Microsoft headquarters @ Schiphol for the recordings. It was really cool to record this video. Together with James van den Berg and Jacco Brouwer we’ve talked about the products Hyper-V and System Center Virtual Machine manager. The video is published yesterday and I’m impressed about the end result:
Sorry for all who don’t understand dutch but I can translate it on request
