In Windows Hyper-V 2012, Move-VMStorage leaves folders behind

I have tested a bit with the WinServ first in the early version 8 and then RC and now RTM, and what I thought was a bug that MS would fix before RTM seems to be still there.

What am I talking about then, well when you do a live or cold storage migration of a VM from for example your local storage to a SMB share either with the gui or preferebly with PowerShell, the built-in function leaves folders behind. And you can see where this is leading when moving a lot of VM´s, several VM´s folders retain with nothing inside and causing confusion!

As you can see on the screendump, the VM 2012 has been moved to another place but the folder still resides with no data in it, the subfolders are there but no disk files. And of course if I use the parameter -RetainVhdCopiesOnSource the folders should stay and also the configuration, vhd files 🙂

So I have done a modified Move-VMStorage function that actually removes the source folder also after moving the VM.

Here is the powershell function and a screendump how it actually deletes the folder also, And as you can see, I check if the VM resides on a share or locally on a hyper-v host and then I use Invoke-Command to delete the folder on the host´s local volume. The script can run on any machine that has RSAT-Hyper-V Powershell tools installed and with an account that has rights to delete folders on the shares/hosts.

   To also remove the folder where the VM was residing this function also deletes the folder after moving the VM

function Move-VMStorage2
        # A name of a VM or a VM object
        # The name of the Hyper-V host
        # The path where the VM is going to be relocated to.

        # Lets move and tidy the source folder
        $VM = Get-VM $VM -ComputerName $ComputerName
        Move-VMStorage -VM $VM -DestinationStoragePath $Path
        $VMOldPath = $VM.Path
        if ($VMOldPath.StartsWith("\\")) {
           Remove-Item -Path $VMOldPath -Recurse -Force
            Invoke-Command -ComputerName $VM.ComputerName -ScriptBlock {Remove-Item -Path $Using:VMOldPath -Recurse -Force}

Make sure that you always add the VM´s name to the path otherwise you will put the VM´s folders and files in the SMB folder directly and that will cause a mess and when you run my function it will try to clean that folder and all subfolders wich means all VM´s not running in that folder. Maybe I will add the control that It checks that the path to delete includes the VM name in a future update 😛

Go to the TEC 2012 conference in Barcelona

This year I will present at the Technology Experts Conference by Quest again. Last year I had a session about how to successfully implement and transition into a Hyper-V platform. And this year I will do two sessions in the virtualization track. There are some very skilled speakers listed and I feel proud to be one of the listed.

Mythbusters go Hyper-V 

Maybe not so much explosions as on TV but I will try to in a fun and entertaining way do some mythbusting in the Hyper-V virtualization world. We will go through some of the common myths out there among IT professionals and implementers. Microsoft Windows Hyper-V has gone through a massive facelift from 2008 R2 to the new 2012 with loads of new functionallity and performance. Maybe you still rely on old information about how to set up and configure your virtualization platform. I have put some of the common claims to test and will show if they are myths or true. Watch out for some irony and jokes during the session.

Powershell is the way to handle Windows Hyper-v 2012

In this session we will look at how to manage Hyper-V in the new Windows Server 2012 with powershell and the cmdlets in the Hyper-v Module. We will look at the new functions that have been released in the new Powershell version 3 and how we can use them when deploying and managing the hosts and the virtual machines. We will in this session go from scratch to a fully deployed environment without using the GUI. In the session we will also look at how to find Hyper-V servers in your Active Directory and what VM´s are running there, we will also look at how to schedule a daily health report on your VM´s and hosts.

Installing vSphere vCenter 5.1 on Windows 2012

I have tested to install the new VMware ESXi 5.1 in a VM on my Macbook pro, next step was to get the vCenter 5.1 working on Windows 2012.

I downloaded the evaluation ISO from technet and when using the Easy Install I got an error trying to install the OS on the VM, as you can see on the screendump I get a licensing error, my first thought was that it was an error with my iso download and I then downloaded it again but the error persisted.

When I try to set up a new VM without the Easy Install I get the license agreement without error and could deploy the VM without any errors. Did I say that I am using the latest fusion 5.0.1

So to continue with the install, when the OS is upp and running I also need to download/install .net 3.5 (this is not by default available in win 2012 so I need the Media or an Internet connection). This as the .Net 3.5 is a requirement when installing vCenter.

Then I run the simple install from the media that will install the vCenter server, Single sign-on and Inventory service together.

When the installation is finished everything seems to be installed but the vCenter service will not start. It complained about a service that it depended on that was not existing.

I investigated a bit and the Protected Storage Service was deprecated in windows 2008 and only in read-mode and I could not find it for Windows 2012. So I wanted to remove the dependent services.

So how to do this, I type sc config vpxd depend= “” to remove all dependencies and then I typed sc start vpxd and the service took a bit to start but eventually it got to a running state.

Then I installed the vSphere Client and tried to log in and when the client opened I added the vSphere host without any issues.

Now when I got this running I will continue to install PowerCLI 5.1 and test it with PowerShell 3.0



New job: Product Manager Private Cloud @Lumagate

Today I have done my last day at Real Time Services and on monday I will start as a Product Manager Private Cloud at Lumagate.

My focus will be on helping customers adopting and implementing a private cloud. It will be very exiting and hopefully some fun developing projects. I will work with both VMware and Microsoft solutions but with a focus on enabling the System Center Suite and automation.

If you want to contact me, this is my new business card:


VM Monitoring with Windows 2012 Hyper-V failover cluster

Today I have tested to set up VM monitoring and see how it works.

Kristian Nese has made a blog post about it, I wanted to do a bit more in Powershell, He also points out that it might in some scenarios not be so good to activate this on a VM that have multiple roles and I must agree in that. Another thing to say again is, this can only be done on Windows 2012 VM´s and they haft to either be in the same domain as the failover-cluster or in a trusted domain and also the cluster nodes must be able to connect to the VM over the network.

First for the cluster to be able to see the services that can be monitored I have to allow that in the VM´s firewall, I will also enable Remote Service Management to communicate so I can remotely check services with powershell.

via PS remote I enable the firewall rules

Set-NetFirewallRule -DisplayGroup "Virtual Machine Monitoring" -Enabled true
Set-NetFirewallRule -DisplayGroup "Remote Service Management" -Enabled true

And then I can do some magic in the powershell console to set up the VM monitoring, I use the -OverrideServiceRecoveryActions parameter so the VM monitoring will trigger first no matter what the service is configured to do in the recovery settings.

Get-Service apache -ComputerName pstest

Add-ClusterVMMonitoredItem -Service apache2.2 -OverrideServiceRecoveryActions -VirtualMachine powertest -Cluster hypclu3

Get-ClusterVMMonitoredItem -VirtualMachine powertest -Cluster hypclu3

And in the Cluster Manager it looks like this:


To test this I want to kill the service and for that I can use the Stop-Process, this can not be used in a cmdlet remote so I have to use remoting again so with the Invoke-Command I get the process and kill it 🙂

Invoke-Command -ComputerName pstest -ScriptBlock {Get-Process httpd | Stop-Process -Force}

And after just a breath the server reboots 🙂

And if I want to remove the monitored services from the VM in the cluster I just run this command:

Get-ClusterVMMonitoredItem -VirtualMachine powertest -Cluster hypclu3 | Remove-ClusterVMMonitoredItem

In this example I have used a third party open source software to show that the monitoring not only just works with Microsoft services. It is as I said in the beginning useful in the right circumstance.

Live Migrate VM´s in Hyper-V cluster from RC to RTM node

Yesterday I upgraded a Hyper-V node in a cluster from RC to RTM, Now I want to live migrate VM´s from the RC node to the RTM and then upgrade that.

As you can see on this screendump I have one node with build number 8400 (RC) and one with 9200 (RTM)

As you can see on this next image I have two VM´s running on my old node and I want to migrate them. The VM´s reside on a SMB 3.0 share and the cluster have a quorum share

And how do I move the VM´s to the other node, yes with powershell also, what you can see is that the Move-ClusterVirtualMachineRole can take the VMid from the VM objects as pipelined input, and that is really nice.

So now I have live migrated over the VM´s from the old RC to the RTM server and I can continue to upgrade that node.

I get an error if I try to live migrate them back to the old node, the only way I can do that is when the VM´s are powered off.


Upgrading my Windows 2012 RC to RTM with Hyper-V VM´s on

Well the Windows 2012 Launch site is probably a bit overloaded.

Anyway, I have downloaded my iso from the technet plus account and now I will start installing.

Here have Olav made a post about how to upgrade from RC to RTM and it is probably not supported but I tried it anyway.

To download the Windows 2012 you just go to technet and chose the evaluation

When it is downloaded I edit the cversion.ini to 8400 and then start the installation,

I like that the core version is default when starting the installation

And now as you can see I can choose the upgrade option

And lookilooki, I can now upgrade with no complaints, or at least just warnings

 And after quite a bit of waiting and reboots the server is actually upgraded and now I have started my VM´s again (yes with Powershell :-P)
