Download the new DPM 2012 R2 UR4 Eval VHD with Powershell and BITS

I was at a customer today and we decided to evaluate System Center DPM for their Hyper-V platform.

I was going to download the Eval VHD that so nicely have been updated with the latest UR4 but I got an irritating error, I reached out on twitter and it was not just me and the internet connection/Firewall I was using causing this as others where also having the same issue 🙁

I later tried this evening and now it worked, they had changed the file extension for download to .ZIP instead of VHD

By using powershell you can just send your req to BITS and sit down and relax until it is finished and then you can evaluate DPM 🙂

Happy backuping and ” Real Men don’t take backup! – Or do they? ”




HyperV local storage available for placement in SCVMM

I have been working with a customer and was going to do an upgrade of one of their Hyper-v clusters to 2012 R2. During my preparations and looking at the particular hosts I found several VM´s that was residing on local storage on the hosts and not on the cluster storage.

The reason for this was two things, first of all that it was allowed to put VM´s on local disks and second that when someone created the VM´s forgot to use the appropriate HW-template that makes them highly available by default. If you create a new VM with a new HW profile make sure that it is configured correctly under the Availability tab.

The Hyper-V hosts have been deployed with Bare-Metal deploy from VMM and that is why they have a D:\

Looking at the properties for a host you can see what storage that is available for placement:

and as you can see the VM is not configured as highly available and have the virtual disk on local storage:

Screen Shot 2015-01-28 at 14.20.24

I have made a simple script that configures all hosts within a cluster and set all storage that is not cluster shared to not available for placement.

And now when trying to deploy a VM with a new HW profile that is not set to highly available I cannot deploy it as the local disks have been unchecked as available for placement.

The reason for just configuring this for hyper-v nodes that belong to a cluster is that there might be a single hyper-v host that actually should be able to provision the VM to local disks.

Configuring VMM logical switch with bandwidth limit virtual port

I got a question from a customer how they could limit a VM´s bandwidth from VMM as it was too noisy and devoured the bandwidth from the host for the other VM´s. There are both a way to set priority and also bandwidth in Hyper-V 2012 and later.

In Hyper-V Manager you can find the setting on the VM´s configuration and the virtual network adapter tab,

Screen Shot 2015-01-16 at 16.15.32

And here I can enable bandwidth management and set both a minimum and maximum, and in this case I want just a limit

Screen Shot 2015-01-16 at 16.15.13

But how do I accomplish the same in VMM? As you might have noticed there is no possibility to edit this on the VM´s settings on the virtual nic, this is a setting that I configure with a Port profile instead and apply on selected VM/VM´s, and by doing it this way I can easily just configure the same profile for several VM´s instead of configuring each VM. There are some configured by default and I can also add new with the particular setting that I need.

First there is the port classification:

Screen Shot 2015-01-17 at 15.49.49

And then the actual port profiles:

Screen Shot 2015-01-17 at 15.48.26

These two combined is used in the Logical Switch for the virtual port,

Screen Shot 2015-01-19 at 11.45.23

Easiest is to use Powershell to create a new port classification and profile and then update the logical switch to be able to use it for the VM´s that needs it, I have made a function that takes care of all the steps including adding it to the logical switch as a virtual port:

Screen Shot 2015-01-19 at 11.54.28

And also a function for removing, in this I check the VM´s connected and moving them to the default port profile before removing it,

Screen Shot 2015-01-19 at 11.55.18

Probably there will be some updates to this in the future but here you can see and test for your own needs 🙂  I will now start to test some bandwidth flooding to see that it actually limits the VM´s




All VM´s reporting: “Unsupported Cluster Configuration” in VMM

Today I was contacted by a customer regarding an issue they had with all their VM´s in their main cluster reporting “Unsupported Cluster Configuration”

The reason was that two of the nodes in their cluster had in VMM 2012 R2 lost their virtual switch and vnics and that resulted in the cluster saying that it did not have a HA-Virtual Switch and thus the VM`s had network connections that was not available on the cluster…

Screen Shot 2015-01-12 at 14.11.41

Searching a bit and checking the hosts and VM´s outside of VMM there was no issues on them and the logical switch and vnics was still there, the vm´s was able to reach the network so clearly a VMM issue.

I tried to refresh the cluster and nodes and also restart the VMM agent on the hosts but that did not help. Looking at the properties in VMM on a host showed nothing where it should be both the switch and the management vnics:

Screen Shot 2015-01-07 at 20.41.48

Using the failover cluster manager and live-migrating the vm´s and then restart the host did though help,

After reboot I refreshed the cluster and the network appeared again, I have been searching for a reason for the issue but have not found anything yet in the logs on either the VMM server or the hosts..

To refresh the VM´s on the cluster to remove the “Unsupported cluster configuration” after I had got the virtual switch back I used powershell

Screen Shot 2015-01-12 at 20.21.12

If you have had this issue or similar I would like to know so please comment the post 🙂

I will search some more and see if I can find the reason for this. It should be said that the customer have two 2012 hyper-v clusters and one 2012 R2 cluster and I have not seen this happen on the R2 cluster yet so maybe it is a 2012 issue… And yes we are working eagerly to move the VM´s to the R2 cluster 😛 , the VMM 2012 R2 server is also updated with the latest UR4



Error 25122 when doing refresh in VMM 2012 R2 UR3->

There is no better way than to start the year and enlighten you with a error I had this autumn at a customer…

After I updated the VMM server to UR3 at a customer I noticed that it started to give a warning (Completed w/ Info) during refresh of the cluster. And when digging into it you can see the reason for it…

Screen Shot 2015-01-07 at 19.45.26

When I set up the Hyper-V cluster I did it outside of VMM, I had though set up the hosts with logical switches and host vNics in VMM network fabric and the different cluster networks was configured with IP-Pools. And for the record, the VMM server have been upgraded from 2012 SP1.

So what was the reason for this, well when I did the cluster setup I used an IP from the Management-IP pool range for the cluster management and had not reserved it, yes I know I should have taken care of it then but did not…

Consensus is that from UR3 the VMM team has fixed the bug and now it reports this when doing a refresh on the cluster object 😛

So how did i mitigate this issue?! I searched and found a german blogpost by Michel Luescher where he solves the issue with powershell, and as you can see when reading the lines is that we find the IP-address object that is of the wrong type and change it to a HostCluster object instead:

Luckily PowerShell is in english so I could understand that part 😉 as my knowledge in the german language is a bit narrow..

Passed the 70-533 Azure Infrastructure exam

Today I had registered for a second try of the 70-533 Azure Infrastructure exam, two weeks ago I tried this exam and failed, this time it was a bit more successful and I passed.


The first time doing the exam I was thinking that my knowledge in Azure would be enough but I was a bit wrong 😛

These last two weeks since my last try I have been studying and exploring the features and documentation on Azure and it is a seriously complex and full-featured cloud platform!

I will in this post give you some advice on what areas I have been studying if you are also aiming for taking this test..

First of all, you can see on the Microsoft Learning page on what areas that is covered in the exam,

Screen Shot 2014-12-30 at 22.15.01

I have used Azuremans blog post about the exam topics, Marius has also made a blog post about the exam and what to read and learn.

I have also used the Microsoft Virtual Academy : Establish Microsoft Azure IaaS Technical Fundamentals course.

Some of the links to Azure documentation and blog post that I have gone through during my hours of learning :

Good luck in your pursue for the Azure certification!

Get and Set powerplan on Windows Hyper-v 2012 R2 Core

In my work on Hyper-V i have been looking at the performance of the hosts and wanted to both check and also be able to set the powerplan. In this post from Scripting Guys, Ed explains how to use CIM for the action to get and set the Power plans and how much faster that is than using WMI.

I have since Windows Server 2008 R2 tried to have the Core version as a best practice when running Hyper-V and in some cases it requires some extra skills and arguments during deployment and management 😉

The interesting part is that it differs between the full version and core as you can see that when I try to use Get-Cim from a Windows 2012 R2 full it works and I can see the different powerplans and also which one is active:

Screen Shot 2014-12-02 at 11.15.25

but when I try in a Windows Server 2012 R2 Core I get the following error “Provider load failure”, I have tried locally on the core and also remote so no difference there. My knowledge about WMI is a bit limited but a quick search says that it might be some missing or  corrupt files but I have tried 3 different servers installed with core so I would say it is something with missing!

Screen Shot 2014-12-02 at 11.33.01

As I want to be able to both check and set the right power plan centrally I have created two PowerShell functions that utilize the Powercfg.exe command within a invoke-command thus this works in Windows Server 2012 R2 Core. I am using regex for getting the active plan and the guid. The Set-PowerPlan can either use switch arguments or an actual Guid.

Screen Shot 2014-12-02 at 20.26.42

My friend and fellow Hyper-V MVP Didier WorkingHardInIT has made a blog post about live migration and why using “High performance”.

If you have any input or ideas how this could be improved or if you got it to work in core with CIM 🙂

Update 20150108

There is a workaround for this, PowerShell MVP Alexandar Nikolic gave me the link to the connect site which shows the following way to get it to work natively in core by copying the missing files:

# Either copy missing files
dir c:\windows\winsxs -inc wcl.dll,slr100.dll,wclpowrprof.dll -rec -EA 0 |
copy -Dest C:\windows\system32 -verbose

VMM agent disappeared on hyper-v host during update

This week I was working with a customer environment and after successfully upgraded their test VMM environment to UR4 it was now time for the production environment.

The UR4 installation went fine and without issues. After that I wanted to update the agents on the Hyper-V hosts. I used PowerShell of course and all agents except one was successfully updated and started reporting to VMM.

I started to examine the one that failed and could see in jobs that it had timed-out:

Screen Shot 2014-11-28 at 15.50.15

And checking on the host I could see that the uninstall of the old agent had been done as the vmm agent service was gone. As this was a hyper-v host in a cluster and the cluster was slightly over allocated I could not remove the node from vmm and then add it in again so,

Screen Shot 2014-11-28 at 15.43.50

Based on this post I went for the way to try to do a manual install on the host and copied the latest agent that i could find in the vmm folder C:\Program Files\Microsoft System Center 2012\Virtual Machine Manager\agents\Amd64\3.2.7768.0 to the host c:\temp

Screen Shot 2014-11-28 at 15.43.10

Important during the installation wizard was to let the perimiter host dialog checkbox to be unchecked as this was a host already in vmm and also in the same domain.

Screen Shot 2014-11-28 at 15.44.42

And doing a check on the services after the install was finished I could see that the VMM agent was installed and now running

Screen Shot 2014-11-28 at 15.45.36

Once that was completed I could do a refresh in VMM and the host was reporting again and could be managed 🙂
