Managing Hyper-V 2012 with Win 2008 R2/7 RSAT tools

February 9th, 2013 1 comment

I have noticed several forum posts about some issues managing the Windows 2012 Hyper-V or the free Hyper-V 2012 Server.

Most of the cases are because people try to use the Hyper-V manager in Windows 2008 R2 or the Hyper-V manager from the RSAT tools in Windows 7.

As you can see on this screendump, you can successfully connect to a 2012 Hyper-V from a Win7 Hyper-V manager. But the features offered in the new Hyper-V is not accessible in this GUI, this causes some confusion when handling the VM´s and the Hyper-V role!

And here you can see that the server HV03 really is a 2012 version:

So for example, when you are going to edit the VM and add a new virtual harddisk you will notice that the new VHDX is not available

And as you can see in the following screendump from a new Hyper-V manager:

Screen Shot 2013-02-09 at 13.04.27

Some things work though, you can set more memory than the Windows 2008 R2 limit and also set more than 4 vCPU´s!

Screen Shot 2013-02-09 at 13.13.43

The ability to setup Hyper-V replica and to move VM´s are absent from the GUI as these are new features.

Yes It works to manage some stuff in the old Hyper-V manager but not all so my recommendation as it is not supported you should install a Windows 2012 or a Windows 8 to manage your new Hyper-V 2012 and also more importanly you will get the powershell module to manage it!

I have made a blog post about how to enable the Hyper-V manager and the Powershell module on the Windows 2012 and Windows 8!

Download all SC 2012 SP1 Evaluation VHD files with PowerShell

February 4th, 2013 No comments

I was going to download the evaluation VHD´s for System Center 2012 SP1 and doing that the manual way by clicking on each of the links on the download pages and that for all SC 2012 products could seriously give you mental illness, If I counted the files correct it is 99 total + documents.

Screen Shot 2013-02-04 at 20.11.43

I found this guest post on the ScriptingGuys page where Marco did a PowerShell line how to not only find the files but also add them to BITS for download.  This script only works on PowerShell v3.0 because it is using the new Invoke-WebRequest cmdlet, and as you can see on the screendump how easily you can get all download links.

Screen Shot 2013-02-04 at 21.12.20

I have set the new url´s for SC 2012 SP1 RTM eval vhd´s  and added the .docx files and also do a check that in the volume you will store them have enough space, I made the assumption that it is approximately 70 GB total (99 files * ~700 MB each)

Here You can copy this and run on your environment, It will take some hours but at least it saves you the time in clicking :-P

# Download all SC 2012 SP1 VHD Eval
# Niklas Akerlund / Lumagate 2013-02-04

# Downloadfolder
$Dest = "D:\VHDEVAL"
$SizeOfSCSP1 = 70GB

# Get Space on volume
$SpaceRemaining = (Get-Volume $Dest.Split(":")[0]).SizeRemaining

if($SpaceRemaining -gt $SizeOfSCSP1){
((Invoke-WebRequest -Uri "").links | ? href -match "rar$|exe$|docx$").href | %{Start-BitsTransfer -Source $_ -Destination $Dest}
((Invoke-WebRequest -Uri "").links | ? href -match "rar$|exe$|docx$").href | %{Start-BitsTransfer -Source $_ -Destination $Dest}
((Invoke-WebRequest -Uri "").links | ? href -match "rar$|exe$|docx$").href | %{Start-BitsTransfer -Source $_ -Destination $Dest}
((Invoke-WebRequest -Uri "").links | ? href -match "rar$|exe$|docx$").href | %{Start-BitsTransfer -Source $_ -Destination $Dest}
((Invoke-WebRequest -Uri "").links | ? href -match "rar$|exe$|docx$").href | %{Start-BitsTransfer -Source $_ -Destination $Dest}
((Invoke-WebRequest -Uri "").links | ? href -match "rar$|exe$|docx$").href | %{Start-BitsTransfer -Source $_ -Destination $Dest}
((Invoke-WebRequest -Uri "").links | ? href -match "rar$|exe$|docx$").href | %{Start-BitsTransfer -Source $_ -Destination $Dest}
[int]$Sum = ($SizeOfSCSP1 - $SpaceRemaining)/1GB
Write-Host "Free up at least $Sum GB and try again!"

Find correlation between vmwp process and VM in Hyper-V 2012

January 30th, 2013 No comments

If you by some reason need to kill the process that is handling the VM in Hyper-V which is the Virtual Machine Worker Process, it can be handy to also know what vmwp process that correlates to what VM :-P or you could accidently restart the wrong VM. Restarting the VM is the default behavior when the process dies.

If you look in the task manager of the Parent Partition you can see the processes.

Screen Shot 2013-01-30 at 13.00.08

If you look a bit deeper into the task manager you can see that each process in the command line have the virtual machine ID and then digging into this with PowerShell you can find out what VMWP process each VM has. I have been trying to use the Get-Process Cmdlet but that left me with no luck, then I found this post by Ravikanth that uses the Get-WmiObject instead, so I used that and altered what process to get.

Screen Shot 2013-01-30 at 16.17.02

I have made a oneliner that does this and as you can see on the following screendump I get a list of the VM´s and the Process Id´s.

Screen Shot 2013-01-30 at 16.24.39

Get-WmiObject Win32_Process -Filter "Name like '%vmwp%'" | Select-Object ProcessId, @{Label="VMName";Expression = {(Get-VM -Id $_.Commandline.split(" ")[1] | Select-Object VMName).VMName}} | ft -AutoSize

Remote management of Windows 2012 Hyper-V Powershell Dism failure

January 29th, 2013 No comments

Last week on the NIC keynote we could hear Jeffrey Snover talk about Windows 2012 and also that the preferred version when installing is Core, but then you will not have the Hyper-V manager locally (yes you could use the PowerShell module….).

Screen Shot 2013-01-24 at 13.09.14

So how do we enable our management station for remote Hyper-V tasks…

If you have a Windows 2012 you can easily just enable the Remote Server Administration Tools for Hyper-V and that preferably with PowerShell

Screen Shot 2013-01-29 at 21.09.24

And if you want to check if you have the Hyper-V management features installed you can use the Get-WindowsFeature

Screen Shot 2013-01-29 at 21.09.51

I usually also add the Failover cluster RSAT feature also to be able to manage the cluster.

Add-WindowsFeature RSAT-Hyper-V-Tools -IncludeAllSubFeature
Add-WindowsFeature RSAT-Clustering -IncludeAllSubFeature

If you want to add the Hyper-V tools in a Windows 8 you would guess that you have to use the DISM tools and there are some DISM cmdlets, You might have noticed that the Hyper-V tools are not part of the RSAT package for windows 8 this as the client Hyper-V role is part of the OS. But either I am doing something wrong or someone in Redmond has not thought this part through regarding the enabling of features in PowerShell for Win8!

because when I try the following Cmdlet with parameters

Screen Shot 2013-01-29 at 22.16.09

Enable-WindowsOptionalFeature -FeatureName Microsoft-Hyper-V-Tools-All

The PowerShell console barf out an error because when trying to add the Management tools with the powershell cmdlet I get info that it needs a parent feature which would be the Hyper-V feature and in this virtual windows 8 client that is not what I want,

When using the Control Panel, Add/Remove software/Windows Features you can add the Hyper-V Management tools in your Windows 8 without adding the Hyper-V Platform!

Screen Shot 2013-01-29 at 16.29.23

I will pursue this with some smart PowerShell gurus and see if they have an answer to why this happens :-)

In the meantime good luck in creating your management pc!

Upgraded from SC 2012 SP1 Beta/CTP to SP1 RTM

January 22nd, 2013 No comments

I have today tested to upgrade the Beta/CTP version of SC 2012 SP1 to the newly released SP1 RTM version for

  • SC Orchestrator
  • SC Virtual Machine Manager
  • SC Operations Manager (Community Technology Preview)

As the articles on technet tells you it is not supported but I wanted to try and see how I could do it in my lab environment and what consequences it would have . I have one DC Server, one VMM/ORCH/SCOM server (maybe not best practice to have all three roles on the same server but it works :-D ) and one Hyper-V host with some lab-VM´s

I started with the Orchestrator and when I connected the ISO to the server/servers and try to install I got an dialog that I already have it installed, but it is the wrong version so I have to uninstall everything first, So did that and then during the installation selected the old DB in the wizard and after that I could see all my runbooks and IP´s still are there.

Screen Shot 2013-01-22 at 16.32.16

Then It was time for the SC VMM, but now the installation guide clearly told me that I had to uninstall the product, although as you can read on the screen dump: if I am running SC 2012 I can retain the database when uninstalling.

Screen Shot 2013-01-22 at 14.05.14

In the uninstall wizard, be sure to check this box:

Screen Shot 2013-01-22 at 14.10.51

And then during the new installation be sure to point out the old database

Screen Shot 2013-01-22 at 14.14.02The installation wizard will then check and ask if you want to upgrade it, pretty nice and for not supporting an upgrade they have made it quite easy to do it anyway!

Screen Shot 2013-01-22 at 14.14.19

Also, the wizard recognizes the library share that I had configured before. In the last step I get an summary that tells me what potential issues might occur with this upgrade, As you can read in the first part it is important to use the same server as the vmm was installed on before and that you use the same service account for VMM this for the Run-As accounts to work!

Screen Shot 2013-01-22 at 14.17.29

When the installation is complete I had to update the Agent on the Hyper-V host.

Screen Shot 2013-01-22 at 14.25.07

After this I continued to upgrade the SCOM, when starting the installation wizard I did not need to uninstall anything and right away the SCOM accepted an upgrade to the RTM version.

Screen Shot 2013-01-22 at 15.01.04

After successfully “upgrading” these components there are some more work that needs to be done, such as the SCOM-SCVMM integration that need upgrading and also Orchestrator IP that should be taken care of but that in another blog post :-)

New version of the free vKernel Server Explorer

January 15th, 2013 No comments

There is a new version of the free Dell vKernel Server Explorer and now the version number is 6.3

What has been added to this valuable tool:

  • Storage Explorer
  • Change Explorer

So with the storage explorer view I can get valuable information about the capacity and also the configuration of the datastores, such as what path selection, number of VM´s and IO etc

With the Change Explorer I get an overview of what has changed in my environment, this is data from the latest 7 days and if I want more I can always activate the vOPS server trial and then buy an license.

The Server Explorer can be installed/imported into VMware vSphere or Microsoft Hyper-V and also Redhat Enterprise Virtualization, and you can connect it to several vCenter servers and also Hyper-V and RHEV at the same time :-)

I have tested to install it on Microsoft Hyper-V, I tried to use the guide and import the VM on a Windows 2008 R2 Hyper-V, this worked excellent. On windows 2008 r2 it is important that the config.xml file is present in the folder of the VM you try to import or it will fail, this is not a problem on windows 2012 hyper-v where you can import VM´s without exporting them first.

I changed the settings for the imported VM to

  • 4096 MB (I have also been able to start it with 2048 MB)
  • removed the legacy Network Adapter and replaced it with a Network Adapter (the synthetic)

Updated: The synthetic Network Adapter cannot be used when deploying on windows 2012 Hyper-V because the IC for linux on the vKernel Server Explorer appliance is version 3.1 and the OS is OpenSuse 11.4, and the IC 3.4 which is needed for 2012 cannot be installed on that OS. You can find out the version on your Linux VM by typing modinfo hv_vmbus or modinfo hv_netvsc for the network adapter. The recommendation from Microsoft is that you should use the Network Adapter when possible.

Screen Shot 2013-01-16 at 12.43.08

Then I started it and although the VM/VHD´s says 6.0 the VM after start says 6.3 So I know it is the latest and it starts successfully.

Screen Shot 2013-01-14 at 14.21.06

Next step is to configure the vKernel Hyper-V Collector, as you can see this is kind of mandatory before adding the System Center in the vOPS Server Explorer.

Screen Shot 2013-01-14 at 14.46.20

There are two different folders on the download and if you have System Center 2012 you should install the Hyper-V Collector 2012. If I had chosen the internal vOPS database I will use the SQL Server type PostgreSQL, the ip adress of the vOPS Server Explorer and the username and password postgres / postgres

Screen Shot 2013-01-14 at 16.05.27

Next step is to configure the connections tab where we add a connection to the SCOM server and when that is done we can after a while check the data in the web, the address is http://ip_of_the_vOPS , the name of my SCOM server is VMM12 so it is not the VMM server I connect to, although this server do have vmm and scom on the same OS.

Screen Shot 2013-01-14 at 21.57.44

Free tools are always nice and with these new change and storage explorers you get more insight into your environment and this for free!!

Good luck in your deployment of this updated tool!

Getting files out of a running VM in Hyper-V 2012 remotely

January 9th, 2013 No comments

I was reading the post by Ben Virtual-PC Guy about how to get files out of a running virtual machine.

I have altered his bits to work also when not running on a Hyper-V host (as Mount-VHD does not work when not Hyper-V is enabled), and you have the VM´s on a smb share, this also works if you take a snapshot and then copy the vhdx file to a windows 8 or windows 2012 machine.

The cool part is that I can use a UNC share path with Mount-DiskImage which is the Cmdlet used.

If I have the right permissions I can then easily with just a PowerShell script as Ben showed mount the virtual harddisk and copy the files, and this from a remote server and not on the Hyper-V host.

Screen Shot 2013-01-09 at 23.28.25

Get-VM core -ComputerName hv01 | Checkpoint-VM -SnapshotName "Need to look at these disks" -Passthru | %{Get-VHD -VMId $_.vmid -ComputerName $_.ComputerName} | %{Mount-DiskImage -ImagePath $_.ParentPath -Access ReadOnly -PassThru}

After I have run this you see that I can then get the secret file out of the running virtual machine

Screen Shot 2013-01-09 at 16.35.22

and when I am finished copying the secret files from the running virtual machine I can unmount the disk and remove the snapshot.

 Screen Shot 2013-01-09 at 23.29.26

PS C:\> Get-VM Core -ComputerName HV01 | Get-VMSnapshot | %{Get-VHD -VMId $_.vmid -ComputerName $_.ComputerName; Remove-VMSnapshot -VMName $_.VMName -ComputerName $_.ComputerName} | %{Dismount-DiskImage $_.ParentPath -PassThru}

So what is the conclusion on this in a security perspective, as you can see it is quite easy for a person with the right permissions on a host level to get access of files that he or she maybe not should see. Talented hackers can get permissions and accounts that they need. This leads to the discussion of course where you should put your hosts, is it enough security and boundaries on your network and in your Active Directory Domain or should you set up another for the Hyper-V hosts and management servers?!

Bug in Powershell v3 on regional settings in Windows 2012

January 9th, 2013 No comments

In my previos post I was claiming that there was a bug in the Get-WinEvent, but the bug is in Powershell v3 and how it works with the regional settings.

I live in Sweden and thus have Sweden as regional format setting and that did Powershell version 3 not like, at least not for the Get-WinEvent cmdlet :-P

Screen Shot 2013-01-09 at 14.02.22

Using powershell to change the format or culture is done with the following

Screen Shot 2013-01-09 at 14.05.06

Set-Culture en-US

Screen Shot 2013-01-09 at 14.13.54

And when I open a new PowerShell Console I can see the messages for my Hyper-V events :-) not so good with the bug though..

Screen Shot 2013-01-09 at 14.18.58

Lets hope there is a bug fix soon, a bit embarrassing when some parts of the powershell console is not working in other regional settings besides en-US, are we in other parts of the world not that important or just an mistake by an developer, lets hope for the later..

A big thanks to Andreas Hultgren that was first to let me know about the bug :-)

Bug in Get-WinEvent on Windows 2012?

January 9th, 2013 No comments

I have been trying to get some Events out of my test environment for some Hyper-V stuff.

What I have noticed when digging down into the Get-EventLog and Get-WinEvent I get different information

The Get-EventLog gives me information and message about the Windows Logs and there it works nicely as you can see

Screen Shot 2013-01-09 at 12.14.07

But when I try to get information from as in this case Hyper-V logs with Get-WinEvent I get no information in the fields LevelDisplayName and Messages?!

Screen Shot 2013-01-09 at 12.21.57

And in the Event Viewer you can see that the information is there:

Screen Shot 2013-01-09 at 12.27.14

Have I misunderstood something how to get the Events in PowerShell or is there a bug in the system? In the old “Windows 2008 R2″ I got the information correctly as you can see on this screendump, so the Get-WinEvent issue is related to Win 2012 version!

 Screen Shot 2013-01-09 at 12.40.54

It kind of sucks if I cannot search the messages for some data and collect that information, and what I can see it seems to be the same case for all application and services logs and I will not accept to have to go the Event Viewer GUI :-)

Populate your own custom properties on SC VMM 2012

December 17th, 2012 No comments

I have been helping a customer to populate their VMM 2012 console with information that they think is good to have, I have made a blog post about this some time ago but now I have added some new valuable information.

The information I retrive are where the VM resides on what CSV volume, if the VM has dynamic VHD´s, if the VM has snapshots and if the snapshots also have been merged, this can only happen when the VM is in Saved State or Stopped on a Win 2008 R2 Hyper-V (this is not an issue on a win 2012 hyper-v as it can live merge)

First I add the Custom Properties

New-SCCustomProperty -Name "DynamicVHD" -AddMember "VM"
New-SCCustomProperty -Name "Snapshots" -AddMember "VM"
New-SCCustomProperty -Name "Datastore" -AddMember "VM"

Here is a screenshot how it looks when you add the custom properties to the console,
Screen Shot 2012-12-17 at 19.41.55

In the powershell script I iterate down through all the snapshots/differencing disks to the parent VHD and check if that is fixed or dynamic. And as you see in the image I check if there is a snapshot or a removed but not merged snapshot (I still have a small problem with the VMM name Checkpoint ;-) )

# Update custom items Snapshots and Dynamic disks, Datastore
# Niklas Akerlund / Lumagate 2012-12-17
if (-not (Get-Module virtualmachinemanager)) {
    Import-Module virtualmachinemanager
Get-SCVMMServer -ComputerName localhost | Out-Null

$VMs = Get-VM 

foreach ($VM in $VMs){
    $Datastore = " "
    $LocationProp = Get-SCCustomProperty -Name "Datastore"
    $SnapShots = Get-SCCustomProperty -Name "Snapshots"    
    $VHDs = $VM | Get-VirtualHardDisk
    $DynDisk = Get-SCCustomProperty -Name "DynamicVHD" 
    $Dyn = $false
    $Merge = $false
    foreach ($VHD in $VHDs){
        if ($VHD.VHDType -eq "DynamicallyExpanding"){
            $Dyn = $true
        if (($VHD.Location -like "*.avhd") -and (($VM | Get-SCVMCheckpoint) -eq $null)){
                $Merge = $true
        $VHDp = $VHD
        while ($VHDp.ParentDisk -ne $Null){
            $VHDp = $VHDp.ParentDisk
            if($VHDp.VHDType -eq "DynamicallyExpanding"){
                $Dyn = $true
    # Update custom values
    $Datastore = $VM.Location.Split("\")[2]
    Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $LocationProp -Value $Datastore
    if ($Dyn){
        Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $DynDisk -Value "Yes" 
        Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $DynDisk -Value "No" 
    if ($VM | Get-SCVMCheckpoint){
        Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $SnapShots -Value "Yes"
        Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $SnapShots -Value "Not Merged"
        Set-SCCustomPropertyValue -InputObject $VM -CustomProperty $SnapShots -Value "No"

As I described in the earlier post you can schedule this to run with scheduled tasks and maybe set it to run every hour or what ever you might prefer.
