Convert to generation 2 on a VM in Hyper-V 2012 R2 with Powershell

I have done blog posts about why you should create your new VM´s with Windows Server 2012 instead of 2008 R2 or older even if you were not able to create them with the generation 2 at that time as the Windows 2012 R2 was not released back then.

I also did a blog post how to use a third party product to do the migration from generation 1 to 2 with Double Take Move software.

Now I found John Howards script that he has made public that does the migration from generation 1 to 2 🙂 He also has a blog series about generation 2 VM´s that is definitely worth the time to check out.

I got an error when running it though and it seems that it does not work so good with the partition on the gen 1 virtual disk..  It appears that when I have created my virtual machine with the Convert-WindowsImage.ps1 script that only creates one partition the row in the script that checks for $partitions.length fails and I could not get it to continue but when I commented that away I got my first conversion on the way 🙂

And here you can se in the PowerShell ISE my alteration  🙂

Now I am sure that John and his team will work and distribute new versions with correct error checking and I am truly glad that they have released this so I could test it right now anyway 🙂 !!

Here is my VM in generation 1

And here is the converted VM,

And here you can see that during the conversion that I have two disks attached to my server and that the one at the bottom has got some new partitions for the gen 2 UEFI boot process

Happy converting and making generation 2 VM´s your standard in Hyper-V

SC VMM 2012 SP1 UR4 – fixes the Cluster resource bug

I have on my blog done a post about how the VMM 2012 Sp1 not updated the cluster resource when doing Live Storage migration from one CSV volume to another in a Hyper-V cluster and now in the Update Release 4 of VMM 2012 SP1 they have finally fixed it!

Here you can see the Issue 13 that has been fixed

Also as in Issue 15 there was stuff left after a canceled or failed migration

One thing that could have been a wish was that they in this UR would have added the Windows 2012 R2 as an operating system, you can run Windows 2012 R2 as virtual machines in your 2012 Hyper-V but not assign the right OS on the properties on the VMM 2012 Sp1 🙁

vmmos

In Hyper-V this does not have an impact for the successful boot as in VMware VM´s where you set the best matching OS for the boot process to work flawlessly. In Hyper-V it uses the same BIOS for all your VM´s and this list is something for VMM and the database.

Strange Creation Date on Hyper-V 2012 R2 VM

I have some VM´s on my new Windows 2012 R2 host that have a strange creation date on the properties.

The VM´s have been created on different times and it was a customer that noticed it.

quite fun as there was not computers or even Hyper-V invented in the 17 century or was it? 😉

Here is my lab/demo VMM 2012 R2 virtual machine and as you can see it is created the 1 of january 1601

WOWAn

 

and here is the other virtual machine, a windows 8 template

I have not been able to reproduce it now with either PowerShell or via the GUI, If you have seen the same issue please comment the post 🙂

Updated download script for evaluation VHD for SysCtr 2012 R2

Now when the evaluation VHD´s have been updated with the release of the System Center R2 that was released last week I have updated my download script so you easily can get all the files at a convenient place with PowerShell and the BITS engine.

Good luck in your evaluation of the System Center 2012 R2 suite 🙂

 

My experience on the newly released VMM 2012 R2 RTM

So as everyone else (at least an ITPRO with some dignity and self respect) I have started to download the System Center 2012 R2 as it was released just some hours ago! The link appeared on my technet subscription page about 1 PM in Swedish time

I started to Install the VM for my VMM and of course I created it as an Generation 2 VM on my Hyper-V R2 host.. In the preview, VMM could not manage gen2 VM´s but now we will see about that. Before installing VMM I had to download and install Windows 8.1 ADK and an SQL server.

Screen Shot 2013-10-17 at 14.26.04

And then when I had an successful installation I wanted to add at least one Hyper-V server, the funny part here is that I have activated Hyper-V on this Windows 2012 R2 and why it is saying unknown hypervisor beats me 🙂 . Fortunately I could proceed to add the host

And then I wanted to check the Gen2 VMM server I had created and see if it was viewable in the VMM console and also the system volume could be expanded when the VM was powered on (in earlier versions of VMM that has sometimes been a nono for example with VM additions )

As you can see there is no possibility in the VMM console to shrink the disk so there I have to use the Hyper-V Manager.. ( I have tried to enter a lower value but the gui won’t allow me to do it) So much for one place for all management.. In the following screendump you can see the option to shrink the storage from the Hyper-V manager wizard.

 And as you remember one of the new fine features in the Hyper-V R2 was the full feature RDP access to the VM through the VMbus, why has that not been implemented in the VMM??

Screen Shot 2013-10-17 at 15.14.40

 This old vmm viewer reminds me of the VMM 2008 with no additional features that I get in the Hyper-V Virtual machine connection..

I will continue to explore the VMM 2012 R2 and there might be some more blog posts coming and until then, good luck in your deployments 🙂

Converting VHD´s to VHDX in SCVMM 2012 SP1 with PowerShell

I have in an earlier post described my little PowerShell function to migrate VM´s from a Windows 2008 R2 cluster to a new Windows 2012 Hyper-V cluster in VMM.

As it is a best practice to convert your VHD´s to VHDX I wanted to do that with SCVMM 2012 Sp1 also. It is a small detail that you need to be aware of when doing it in the VMM console, it does not remove the old VHD file from the datastore and in the GUI it is no checkbox for that either. This is the case for both VMM 2012 SP1 and R2 Preview. And if you start converting several VM´s VHD´s there is a possibility that your datastore will become full quite fast and that is not so good!

Screen Shot 2013-10-04 at 14.39.44

And on the folder where the virtual harddisk resides you can see that the vhd still exists..

Screen Shot 2013-10-04 at 14.57.15

In the PowerShell cmdlet Convert-VirtualDiskDrive there is a parameter -deletesource that removes the VHD once the conversion has completed 🙂

So I have made a PowerShell function if you want to convert all your VHD´s on the virtual machine.

Good luck in getting the Hyper-V 2012 environment in the best shape ever before moving to 2012 R2!
