A customer of mine is planning to consolidate several Hyper-V clusters into one or two big ones.
In order to do that, I had to report on the amounts of memory currently offered by the Hyper-V hosts and the memory configurations of the virtual machines.
When I would use MAP, yet another tool would be introduced into the environment… and only to report on the memory configuration? It seemed to me that this would be a bit overkill.
But then there is SCOM. This customer already has SCOM implemented and configured… but since I’m a n00b when it comes to SCOM this would not have been my favorite solution for such a simple task.
So I turned yet again to my buddy PowerShell ![]()
I created a small one-liner to provide an output of all the VM’s, their respective nodes, the amount of memory offered by the nodes and the memory configuration of the VM’s.
Note: This one-liner looks at static memory configurations, not dynamic memory configurations and is based on the SCVMM PowerShell cmdlets!
Get-VM -vmmserver SCVMM01 | select name,memory,vmhost,@{n=’TotalMemoryOfHost(GB)’;e={"{0:N0}" -f ((Get-VMHost &_.VMHost).TotalMemory/1MB)}} | sort VMHost | convertto-html > D:\Temp\MemoryConfig.html
This will give you an output looking like this:
Last November I went to the Experts 2 Experts Virtualization Conference in London where I met some other Hyper-V enthusiasts.
One of them was Carsten Rachfahl (MVP Virtual Server) who does frequent video interviews with leading experts in the Microsoft IT community. He asked a bunch of us if he could interview us which all of us were happy to do ![]()
First up was Aidan Finn (MVP Virtual Server). Aidan also did two presentations at the event, one about what he could tell us about Hyper-V 3.0 and one about designing your backup solution when using Hyper-V Cluster Shared Volumes (CSV) which were both very interesting… His interview is also about designing Hyper-V CSV and Backup:

Carsten’s second victim was Didier van Hoye (MVP Virtual Server since this month… congrats Didier!). Didier did a presentation at the event about 10GB networking in Hyper-V and found this to be very educational ![]()
His interview is about Cluster Shared Volumes and Storage design in Windows 8:

Third up was Ronnie Isherwood who lives in Jersey (no, not that city in the USA but that small island between the UK and France…). Ronnie also did a presentation at the event, about System Center Virtual Machine Manager (SCVMM) 2012 although I had to leave in the middle of the presentation because a colleage contacted me from back home (The Netherlands) with a critical issue and needed some advice. So, altough I was unable to see most of Ronnie’s presentation I heard it was a good one (didn’t expected anything else though
).
His interview with Carsten is about SCVMM 2012, among others it’s multi-hypervisor support:

And the fourth person able to get in from of the camera was… me
. I did a presentation at the event about the v-Alliance from Microsoft and Citrix, which was my first presentation at an international IT event.
My interview on the other hand was about the combination of my two favorites: Hyper-V and PowerShell:

And to close a few days of deep technical sessions, meeting community peers and of course a lot of fun, we did a group interview (featuring all of the above) about our favorite Hyper-V feature in Windows 8:

During the entire event we’ve talked with each other about a lot of things… and I’m hoping some of the ideas will come to see the light of day in 2012… I’ll keep you posted ![]()
