Live migrating VM´s between clusters in VMM 2012 R2

October 17th, 2014 No comments

Today I have been doing some work at a customer creating a Hyper-V 2012 R2 Cluster and starting to live migrate VM´s from their Hyper-V 2012 Cluster.

Doing that from VMM gave me some errors and here is the solution so that if you happens to get into the same problem :-)

First of all, when added the new cluster to VMM I tried to live migrate a VM but got this error (12700)

Screen Shot 2014-10-17 at 19.30.43After a quick search on the net I found this blog post explaining the need to configure kerberos live migration and delegation between the hosts and also that the hosts needs an “Host Management Credentials” account set up in the properties! I had already set up the hosts to use Kerberos and delegation between and still got the above error but when checking the Run As account it was empty:

Screen Shot 2014-10-17 at 15.53.45The problem as you can see though, it is greyed out and cannot be altered, I tried to do add an account through PowerShell and there I got an answer that it had to be set on the cluster,

Screen Shot 2014-10-17 at 21.37.08

checking on the cluster properties in the VMM console there is nowhere to add or see the management credential

Screen Shot 2014-10-17 at 21.32.37

So back to PowerShell again:

And when this is set all the cluster hosts have this credential set and then when doing a Live Migration it succeeded :-)

MVMC 3.0 released with P2V support

October 13th, 2014 3 comments

The day has come with a new version of the free conversion tool from Microsoft, MVMC 3.0 have been released.

There where some bashing on the net when the VMM 2012 R2 was released and the P2V functionality was removed from that version and some crazy ideas using a secondary VMM 2012 SP1 to do the P2V migrations and then importing into the VMM 2012 R2 was suggested, well that time is now no more now :-)

The installation is quite straightforward with the msi and just a simple wizard.

Screen Shot 2014-10-13 at 20.21.47

Once installed You can start exploring the new options including the new P2V.

Screen Shot 2014-10-13 at 21.44.18

When doing a P2V the MVMC will install an agent on the source and when doing a P2V the source have to be online during the migration.

Screen Shot 2014-10-13 at 21.55.40

And then you go through the wizard and start the conversion

Screen Shot 2014-10-13 at 22.18.29

 

Screen Shot 2014-10-13 at 22.30.10

Once it is finished, you find the VM in your Hyper-V host and can start it, but beware that the wizard does not ask if you want to shut down your source after migration so that is something you have to take care of before starting that P2V´d VM

Screen Shot 2014-10-13 at 23.29.34

But wait you say, I have 100 vm´s and will die if I use the wizard for all of them! Then you can use the PowerShell module and automate the conversion:

Screen Shot 2014-10-13 at 22.14.32

The operating systems that is supported migrating with the MVMC are (although only Windows with the P2V):

  • Windows Server 2012 R2 Standard x64
  • Windows Server 2012 R2 Datacenter x64
  • Windows Server 2012 Standard x64
  • Windows Server 2012 Datacenter x64

Download SysCtr Tech Preview VHD´s with PowerShell

October 12th, 2014 No comments

Now that the Windows Server Technical Preview and also the System Center Technical Preview have arrived everyone wants to start testing, I have in an earlier post done some initial testing of the new Hyper-V features.

If you want to quickly test the released System Center Tech Preview then use the preinstalled VHD´s that helps you get up and running much faster than installing on your own :-)

The released System Center Tech Preview roles are

  • System Center Virtual Machine Manager
  • System Center Orchestrator
  • System Center Operations Manager
  • System Center Data Protection Manager
  • System Center Service Manager

I have in earlier post showed how you can download all the VHD´s for System Center 2012 R2 and of course I could not use that script right of the shelf for downloading the tech preview as someone have done changes on the web page, but here is it! And I have also added some more functionality for you to choose which of the roles you want or all.

First of the changes gives for some reason duplicates of each file url from the web page I collect the download url´s I want to download and to get around that I use the superduper cmdlet and parameter Select-Object -Unique which gives me an array with all files just once ;-)

Screen Shot 2014-10-12 at 21.24.57

Secondly with Invoke-WebRequest PowerShell uses IE under the hood and I get this dialogue and to get rid of that i use -BasicParsing and that lets PowerShell use its own parser.

Screen Shot 2014-10-12 at 21.15.10

And as you saw in the above screendump I utilize Switch parameters so you can choose which of the roles you want and here you can see the script and copy to your own lab server and start downloading to test!

And by the way, make sure that you either have enough storage available on C: or what drive and folder you want to save it to with the -Dest parameter!!

Observe also that you probably will start the download and go for a walk or sleep as it is quite some data that will be downloaded!

Happy testing!

Hyper-V in new Windows Server technical Preview

October 1st, 2014 No comments

So today Microsoft released their technical previews of Windows 10 and also of Windows Server

As an Hyper-V interested guy I wanted to check out some things in this build, there have already been a blog post about cool features such as rolling cluster updates so that you can have different versions in the Hyper-V cluster and keep the VM´s up all time during an upgrade.

There are some more info on the technet site discussing the different new features:

http://technet.microsoft.com/en-us/library/dn765471.aspx

I downloaded the Windows Server technical preview from my MSDN and started the installation, it was really fast (and yes I have an SSD)

Screen Shot 2014-10-01 at 20.47.40

In this screendump you can see that 5.0.9841.0 version of the PowerShell is included in the server technical preview

Screen Shot 2014-10-01 at 20.16.03

And as you can see there is 182 cmdlets for the new Hyper-V PowerShell module

Screen Shot 2014-10-01 at 20.15.20

After you have moved your 2012 or 2012 R2 VM´s you can update the VM configuration to the latest version but beware that once done that you cannot move those VM´s back to the old Hyper-V host.

Screen Shot 2014-10-01 at 21.48.18

A new feature in this version is also that you can make snapshots (yea I still not like Checkpoint name) that uses VSS, and if that is not available it will fail-back to standard snapshots

Screen Shot 2014-10-01 at 21.44.49

And still in this version you can via PowerShell enable Processor compability for those Windows NT server ;-)

Screen Shot 2014-10-01 at 21.49.22

Screen Shot 2014-10-01 at 21.50.33

When I get some more time I will dig some more into it and do a follow up post

happy testing!

Hyper-V Failover Cluster Validation – think twice

September 22nd, 2014 1 comment

I was talking to some guys with a quite solid VMware background and they were working on setting up a Hyper-V cluster with Windows Azure Pack as frontend.

Their environment was a traditional setup with Hyper-V hosts connecting to a SAN with FC thus using CSV´s for storing the VM´s. All VM´s including their management was configured on these hosts.

As a best practice they ran the Failover Cluster Validation (and yes you should run it or you won’t get support) but as I will show you, they had an unwanted restart of their VM´s including the one they had failover cluster manager started so look and think twice before starting that validation with all tests!

with no HA – VM´s there are not so much to think about but once you add VM´s there is, and it can have some consequences…

If you in the wizard add the CSV volume to the test  you can see the warning showing that you will get the VM´s stopped doing the validation,

Screen Shot 2014-09-22 at 10.55.27

Going next in the wizard and then going back the warning has disappeared!

Screen Shot 2014-09-22 at 10.56.39

But of course in the Confirmation it still says that the VM roles will be stopped but if you are in a hurry and start the validation then all VM´s on the CSV volumes will be stopped and then started and maybe that was not what you had intended from the beginning!

Screen Shot 2014-09-22 at 10.56.27

So look and select the options carefully when doing a validation of a cluster with production workloads in :-)

Automation the future of IT Operations or prepare to die

September 19th, 2014 No comments

So you are an IT Pro or maybe an CIO or CTO and have been sleeping under your desk the latest years or so? But the IT Operations departments are under a lot of stress these days coping in being able to deliver the services to the business in the pace that they demand! Do you recognize this? For example your development division request 50 VM´s and wanted them yesterday, Your response is that come back in a week or two….

Many IT departments are seeing their internal customers such as Dev or Business going outside of the organisation and buying their services directly from Azure or another public cloud provider delivered instantly and that also cheaper than you could produce internally..

Here the Hybrid way of thinking becomes important and why, well you will not be able to compete with all the services that the public cloud can give you in a cheaper and more reliable way so IT Operations of tomorrow will utilize the public cloud as their own and be able to use it for their needs where their private cloud lacks functionality or capacity and in that way respond to the requests from the departments.

Giving the users an self service portal where they can order and see the cost of their engagements is an important part of this and when you implement this you have to have  automation as a key part because the users want things to happen when they press the build button!

51075482-98cb-11e3-82f1-12313b12ccaf-large

Taking Microsofts Azure data centers as an example, they have automated enormously and that from the physical layer all the way into the virtual machines and networks. How does this automation gain you with your environment and becoming more agile and not just run around putting out fires but being able to address the needs of the company IT challenges today and also tomorrow!

Some say that we are in the second machine age and that the IT will have to change big time. Just look at the public cloud Company’s and their services, if they would have done things in a traditional way they would have to charge xx times the amount the charge for their services and also be xx more manpower on the data centers to cope with the day to day operation.

In the latest year Microsoft have released several automation solutions that have been developed and gives you the tools for this must-have automation platform. First of is the Service Management Automation (SMA) which is a robust orchestration engine based on PowerShell workflows and this has also been released as Azure Automation. Secondly we have Microsofts investment in Desired State Configuration and here this also utilize PowerShell. The DSC have some development left but it is so powerful and really large web services utilize this today and keeping their massive services compliant and up to date! DSC can be used for provisioning different things including third party software solutions and for example, Microsoft Azure offers different web services (jomla, wordpress etc) deployed in an automated way probably with some DSC technology behind the curtains.

Of course this gigantic automation project will not be done over a night and will cost quite a bit of money in initial investment but the winning and surviving IT Department is the one successful in their automation processes!

9 years ago I started an onboarding automation process and on that time I had VB script to work with but that manual labor every time a new employee was hired was painful and so boring and already at that time I found the will and inspiration to learn techniques to automate. Still today there are several processes in companies that are perfect candidates for automation but for some reason still being done manually…

Let me help you get Strategic in your IT (automation) delivery!

Error 21161 when doing Bare-Metal deployment on VMM 2012 R2

September 13th, 2014 1 comment

Yesterday I was testing Bare-Metal deployment on a VMM 2012 R2 with a new Hyper-v image and got the error 21161 during the process of making a physical machine into a Hyper-V Server.

Screen Shot 2014-09-12 at 13.40.25

I did of course check the library server (which was the same as the VMM server) and also that the vhdx that contains the Hyper-V image was in the library. I also checked the profile where the reference to the VHDx is and everything looked good.

The error was resolved when checking out the library server properties and changing to a host group instead of the default.

Screen Shot 2014-09-12 at 11.37.18

I have been deploying servers from this VMM before and why it started to complain right now is a mystery and I will dig and see if I can find the reason and if I do you will get an update on the blog, but now you know how to get it running :-)

Update: Daniel Clarke mentioned my fix, In the VMM I have as this error occured I had not updated to UR3 during the time between the deployments which would otherwise had maybe explained the error. I have now updated the server to UR3 and can still do bare-metal deploy.

happy deployment!

New Emulex drivers available at HP support

September 9th, 2014 No comments

I have been helping a customer a while with their Hyper-V environment and now I saw on twitter that HP had new Emulex drivers that could be downloaded so I thought that I should give it a try, there has been quite a storm about the problems with VMQ and Emulex and if you want to read more about that you can check out this link to my friends at Hyper-V.nu . My experience of this problem is that it have been on Gen8 HP blades with a newer Emulex networking on them. Right now I only had G7 to test on.

Screen Shot 2014-09-09 at 21.43.55

 

As a best practice I run the Hyper-V hosts in Core but that did not give me any issues when installing (yes I use VMM bare-metal deployment and will after verified success update that to have this latest drivers )

Screen Shot 2014-09-09 at 21.59.07

 

As it is networking drivers I lost my RDP session for a few seconds before it was fully installed and then I could see the result

Screen Shot 2014-09-09 at 21.59.45

 

And checking with powershell Get-NetAdapter I can verify that the GUI is not lying :-P

 

Screen Shot 2014-09-09 at 22.08.19

And also you can see that the VMQ is enabled for my two NIC´s

Screen Shot 2014-09-09 at 22.44.37

 

Here you can find the HP drivers for in this case a HP BL460 G7 .

Going from an iPhone to a Windows Phone

September 8th, 2014 No comments

I have now in a couple of weeks been testing a Nokia Lumia 930 phone and it is soon time to return it. Importantly that need to be said here is that I have been using iPhones since 2008 and also for a short while I used an Android phone and quite quickly went back to the iPhone.

The iPhone and Apple has been very successful with their devices since the first came out. The amount of apps available for IOS is huge and companies and governments also have adapted and created usable apps for making the life of the user smooth.

The Windows Phone in it´s earlier versions have had its ups and downs and I have not seen it as a possible replacement before the version 8 of the OS and later..

Now as I have lived with the phone and tried to adapt I can really say that I like it.. the build quality is magnificent and the screen looks great, it is fast and I can manage my daily tasks, it is obvious that the development of the OS have got some attention and Microsoft have thought through how the phone should work and with the new features like for instance Cortana it is in the edge of Phone OS development..

nokia-lumia-930-groen

Still I miss my banks app but they say that it is coming this year so when that one have arrived I can buy me self a beutiful Lumia ;-)

Some of the apps I have installed:

  • Waze
  • SAS Scandinavian Airlines
  • Skype
  • Spotify
  • SVT Play
  • Swish
  • Yammer
  • Amazon Kindle
  • Easy Park
  • Facebook Beta
  • GoPro
  • Instagram Beta
  • Lync 2013
  • Netflix
  • Office Lens
  • PC Remote
  • Twitter
  • WinRunner

There are of course more apps that would make it into the cut and the development of new apps go blazing fast so just because your favorite app right now only exist for Android or IOS that will change in a near future. I think we will see a fast changing map now that Microsoft owns the phone division of NOKIA and can make the momentum for devices and solutions that would attract new users that most likely could have been stuck with an iPhone before..

So when you are going to change device next time, think twice and look at the Lumia phones!
