I know a lot of you are, just like me, actively investigating Windows 8 & Hyper-V. You’re downloading the Beta, reading blog post, discussing scenarios and use cases and that’s great. You’re investing in a bright future
Here are some blog post that contain gems of information and that I’d like to bring to your attention:
I already mentioned that during the Experts2Experts Virtualization Conference I met a lot of great people and I presented on High Performance & High Availability networking for Hyper-V clusters (10Gbps goodness). Some of the people I met I already knew from the on line community and others were unknown to me until that event. Among the attendees we found some of the usual virtualization suspects in our community like Aidan Finn, Jeff Wouters, Carsten Rachfahl, Ronnie Isherwood.
Now Carsten Rachfahl is a MVP in Virtual Machine expertise but he’s also a dynamic entrepreneur who shows a lot of initiative. Using social media he is really making in effort to get people & customers to notice important snippets of information by providing easy and fast access to them. He’s very active as a speaker, on Twitter and on his blogs. On top of that he does podcasts and video interviews. For Hyper-V information go to http://www.hyper-v-server.de/ which you can also use as an entry point for his other sites focusing on several aspects of IT in the Microsoft sphere in Germany. Like cloud computing & Licensing. There you’ll also find the videos of interviews on these subjects. It’s quite an impressive endeavor.
Carsten took the opportunity to make some videos with all the above suspects on various subject and he recently released our interview.
In this video we continued the discussion that Aidan started on CSV and we briefly touched on a subject you could make hour long documentaries about: storage options in Windows Hyper-V now and in the years to come. Enjoy!
As I’m building or extending a number of Hyper-V Clusters in the next 4 months I’m gathering/updating my list with the Windows 2008 R2 SP1 hotfixes relating to Hyper-V and Failover Clustering. Microsoft has once published KB2545685: Recommended hotfixes and updates for Windows Server 2008 R2 SP1 Failover Clusters but that list is not kept up to date, the two hotfixes mentioned are in the list below. I also intend to update my list for Windows Server 2008 SP2 and Windows 2008 R2 RTM. As I will run into to these and it’s nice to have a quick reference list.
I’ll include my current list below. Some of these fixes are purely related to Hyper-V, some to a combination of hyper-V and clusters, some only to clustering and some to Windows in general. But they are all ones that will bite you when running Hyper-V (in a failover cluster or stand alone). Now for the fun part with some hotfixes I’ll address in this blog post. Confusion Take a look at the purple text and the green text hotfixes and the discussion below. Are there any others like this I don’t know about?
When you try to install the hotfix it will. So is it really in there? Compare file versions! Well the version after installing the hotfix on a W2K8R2 SP1 Hyper-V server the version of vmms.exe was 6.1.7601.21642 and on a Hyper-V server with SP1 its was 6.1.7061.17514. Buy the way these are English versions of the OS, no language packs installed.
With hotfix installed on SP1
Without hotfix installed on SP1
To make matters even more confusing while the Dutch KB article states it applies to both W2K8R2 RTM and W2K8R2SP1 but the English version of the article has been modified and only mentions W2K8R2 RTM anymore.
