Nice to Know – HP FlexFabric 10GB 2-port 534FLB Adapter can cause network issues using NVGRE

Posted by Mikael Nystrom on February 5, 2015

Today I was working at a customer site, setting up a NVGRE Gateway in a Fabric domain. Install, configuration, all went nice and smooth until we should test and verify that the VM’s could access the network, found a miss configuration and then, hey it was working, well TCP was working but NOT UDP, wtf??? Some troubleshooting (Google and Bing and some cursing) and it seems to be some various obscure things, some hotfixes but then we found something that actually worked…

The issue: Encapsulated Task Offloading

I’m pretty sure that the idea behind it is all good, but of course as all “great” things, it does not work in this combination.

Here you can se the setting that needs to be disabled and you can also see the driver version and date that was in place.

The Solution: Disable it!

But, if you disable it on every hyper-v host (not only the hosts running the NVGRE gateway), it starts working. At the time we could not find any other solution then to disable it.

In this case the customer (and you know how you are) was kind enough to let me post the script that was used to disable this “amazing” technology.


or here in plain text form

$Nics = Get-NetAdapterAdvancedProperty -DisplayName “Encapsulated Task Offload”

foreach($Nic in $Nics)
Set-NetAdapterEncapsulatedPacketTaskOffload -Name $Nics.Name -EncapsulatedPacketTaskOffloadEnabled:$false

Nice To Know – Generate the -JobGroup ID in SCVMM Scripts

Posted by Mikael Nystrom on January 28, 2015

When working with SCVMM it is common to perform administrative tasks using PowerShell. One very nice thing in SCVMM is that when using the UI it will create a script in the end and the idea is that you should be able to use that script and you can, one time…why?

…because you need to generate a new ID every time you run the script, so how do you do that?

Generate a GUID using PowerShell:

$JobGroupID1 = [Guid]::NewGuid().ToString()

The result when generating a GUID.

Using the generated GUID in a SCVMM PowerShell script

Here is a list of CMDlets that uses _JobGroup

Nice to Know – Improve Bare Metal Deployment success rate in System Center Virtual Machine Manager

Posted by Mikael Nystrom on November 5, 2014

Bare Metal Deployment in SCVMM is a bit different compared to everything else, since it is using a push method. So instead of having some kind of client application controlling the deployment, the SCVMM server is controlling the OS Deployment. There could be issues, since SCVMM is building team and switches and there is a chance that SCVMM will loose connectivity to the host and the Bare Metal Deployment stops. In many case that is related to DNS and DNS cache, since that is the method used to be able to connect to the host during deployment. By decreasing the DNS cache timeout on the SCVMM server the success rate will improve very, very much.

How to fix it?

Logon to your SCVMM server and execute the following PowerShell commands to set the DNS Cache to a minimum and restart the DNS Cache services

New-ItemProperty "HKLM:\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters" -Name "MaxCacheTtl" -Value 5 -PropertyType "DWORD" -Force
New-ItemProperty "HKLM:\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters" -Name "MaxNegativeCacheTtl" -Value 5 -PropertyType "DWORD" -Force
Restart-Service -Name Dnscache -Force -Verbose

Nice to Know–Microsoft Virtual Machine Converter 3.0 released to web

Posted by Mikael Nystrom on October 13, 2014


Now with P2V, yes!

New Features in MVMC 3.0
The 3.0 release of MVMC adds the ability to convert a physical computer running Windows Server 2008 or above server operating systems or Windows Vista or above client operating systems to a virtual machine running on Hyper-V host.

Standard stuff is:

  • Converts virtual disks that are attached to a VMware virtual machine to virtual hard disks (VHDs) that can be uploaded to Microsoft Azure.
  • Provides native Windows PowerShell capability that enables scripting and integration into IT automation workflows.
    Note The command-line interface (CLI) in MVMC 1.0 has been replaced by Windows PowerShell in MVMC 2.0.
  • Supports conversion and provisioning of Linux-based guest operating systems from VMware hosts to Hyper-V hosts.
  • Supports conversion of offline virtual machines.
  • Supports the new virtual hard disk format (VHDX) when converting and provisioning in Hyper-V in Windows Server® 2012 R2 and Windows Server 2012.
  • Supports conversion of virtual machines from VMware vSphere 5.5, VMware vSphere 5.1, and VMware vSphere 4.1 hosts Hyper-V virtual machines.
  • Supports Windows Server® 2012 R2, Windows Server® 2012, and Windows® 8 as guest operating systems that you can select for conversion.
  • Converts and deploys virtual machines from VMware hosts to Hyper-V hosts on any of the following operating systems:
  • Windows Server® 2012 R2
  • Windows Server® 2012
  • Windows Server 2008 R2 SP1
  • Converts VMware virtual machines, virtual disks, and configurations for memory, virtual processor, and other virtual computing resources from the source to Hyper-V.
  • Adds virtual network interface cards (NICs) to the converted virtual machine on Hyper-V.
  • Supports conversion of virtual machines from VMware vSphere 5.5, VMware vSphere 5.0, and VMware vSphere 4.1 hosts to Hyper-V.
  • Has a wizard-driven GUI, which simplifies performing virtual machine conversions.
  • Uninstalls VMware Tools before online conversion (online only) to provide a clean way to migrate VMware-based virtual machines to Hyper-V.
    Important MVMC takes a snapshot of the virtual machine that you are converting before you uninstall VMware Tools, and then shuts down the source machine to preserve state during conversion. The virtual machine is restored to its previous state after the source disks that are attached to the virtual machine are successfully copied to the machine where the conversion process is run. At that point, the source machine in VMware can be turned on, if required.
    Important MVMC does not uninstall VMware Tools in an offline conversion. Instead, it disables VMware services, drivers, and programs only for Windows Server guest operating systems. For file conversions with Linux guest operating systems, VMware Tools are not disabled or uninstalled. We highly recommend that you manually uninstall VMware Tools when you convert an offline virtual machine.
  • Supports Windows Server and Linux guest operating system conversion. For more details, see the section “Supported Configurations for Virtual Machine Conversion” in this guide.
  • Includes Windows PowerShell capability for offline conversions of VMware-based virtual hard disks (VMDK) to a Hyper-V–based virtual hard disk file format (.vhd file).
    Note The offline disk conversion does not include driver fixes.

Issue (Hyper-V/SCVMM) – VMM cannot complete the host operation on the HOST server because of error:Storage for virtual machine ‘HOSTNAME’ failed with error ‘The device is not ready.’ (0x80070015)

Posted by Mikael Nystrom on August 28, 2014


When trying to migrate a VM’s storage to a local device using SCVMM you could see this:

Error (12700)
VMM cannot complete the host operation on the HOST server because of the error: Storage migration for virtual machine ‘VM’ (GUID) failed with error ‘The device is not ready.’ (0x80070015).

Operation not allowed for virtual machine ‘VM’ because Hyper-V state is yet to be initialized from the virtual machine configuration. Try again in a few minutes.(Virtual machine ID )
Unknown error (0x800c)

When trying to migrate a VM’s storage to a local device using Hyper-V manager you could see this:

"Storage migration for virtual machine"HOST’ failed.
Operation not allowed because the replication state is not initialized.
Storage migration for virtual machine "HOST’ failed with error ‘The device is not ready’ (0x80070015)."


So far the only solution I have found, tried (and it did work) is to restart the Hyper-V management service.

Nice to Know–Bare metal deployment in SCVMM using Custom script and Custom resources could fail

Posted by Mikael Nystrom on May 4, 2014

The bare metal OS deployment function in SCVMM has the ability to be customized by adding custom scripts (also know as GCE). Basically there is two ways to do this, you either make sure the  script is in the WinPE image or you add it using recourses in the SCVMM Library. There are two locations for those scripts, Pre and Post and the problem seems to be true when we are doing Pre OSD GCE’s. So how do I know it fails then?, well that is not that hard. It will give you a very informative message in the job log like this:

Error (2941)
VMM is unable to complete the request. The connection to the agent on machine has been lost.
Unknown error (0x80072efe)

Recommended Action
Ensure that the WS-Management service and the agent are installed and running and that a firewall is not blocking HTTPS traffic.


And if you open the vmmAgentPE.exe.log file on the host you are deploying you will se this:

058C.05C4::05/04-12:23:13.425#00:OSDDownloadFileFromUrl.cpp(88)[000000000306EB: ThrowOnWin32Failure : 80072efe. Operation attempted WinHttpReceiveResponse(m_hRequest, NULL)
058C.05C4::05/04-12:23:13.425#00:exceptions.cpp(97)[000000000306EB: CarmineException::CarmineException: CarmineError: 1051488,  hr: 0x80072efe

If you look at the last file it tries to download you will see that it is trying to download the file and if you check the size of the file you will se that the size is 0 bytes and “carmine” does not like to transfer 0 size files in WinPE.


Modify the in notepad.exe and type whatever you like, close it, done. If you try once more it should work.

Nice to Know–Management Pack for Windows Server 2012 R2 Hyper-V has an Issue

Posted by Mikael Nystrom on April 16, 2014

The Issue:

ID: 26001 – Microsoft.SystemCenter.VirtualMachineManager.2012.Report.VPortUsageCollection

Got null results from Select Connection from Msvm_SyntheticEthernetPortSettingData where InstanceId=

The “Solution”:

To be honest, there is no real solution so far, the reason is that the MP is looking for the WMI data in the “old” V1 place, and in R2 that is gone, that information is in the new namespace V2. There should be a new MP, but so far I have not seen one. So the only solution is to turn this collector of and that solves only one issue. The event log looks “nice”. In my world that’s is not a solution…

Nice to Know–Deploying Applications using System Center Virtual Machine Manager 2012 (SP1/R2) in UI or in PowerShell

Posted by Mikael Nystrom on August 21, 2013

Yes, I know, there other methods to deploy applications, but sometimes it make sense to use SCVMM to deploy applications to the host machines that you manage. If we look on this from a new and more modern way, SCVMM will be the System Center member that does the deployment of the “only” needed physical machines, that is the Hyper-V hosts and the fileservers used to store the VHDx files over the the SMB network, maybe there is no Configuration Manager Server in this datacenter for any reason.

The App = HP Service Pack

In this case we are going to deploy the HP Service Pack to our hosts since we need that to be able to monitor correctly using OpsMgr (When using an Agent) amongst many things. The Application can be “pushed” from a central location but in this case we are going to run the application locally on each and every server and reboot it if needed. The Command to make a silent express install is HPSUM.exe /express_install and you download the Service Pack for the Proliant servers from ( After downloading the ISO, mount and extract and share the folder so it is accessible to all your hosts.

The GUI Method

Rater easy actually, we can use the “Run Script Command” that is available on every server in the SCVMM Console and then fill out all the parameters


Fill out the parameters like this:

-Executable program: \\vmm01\CD\hp\swpackages\hpsum.exe

-Parameters: /express_install

-Timeout: 1800


–Standard Output: Do not match

–Standard error: Do not match

–Exit Code: Do not Match

–Action when matched: Warn and Continue

–Job restart action: Ignore Script

–Always restart after the script has finished running: Checked

–Restart the computer or virtual machines if the specified exit code is returned: Unchecked


Summary using the UI:

This will work, but not they way I wanted it to, the problem is that I cannot define my own values in the dialg boxes, as an example the application HPSUM.exe will return exit code 1,2 or 3 when it needs a reboot and that cannot be “picked” in the dropdown list, however, using PowerShell well be easier, better and faster since you can define all the applications in an XML file wit all the different settings. so lets drop the UI and switch over to what works and make sense, PowerShell :-)

The PowerShell Method

In this case we will use the same engine, but fire it of using PowerShell instead, it gives us more flexibility and more control

Step Number One – Create the Apps.XML

Here we create an XML file that contain all the settings for all the different application we would like to deploy and here it how it looks:


as you can see it contains the application, arguments, reboot settings and all the return codes this application could return when it “feels” that it needs a reboot

Step Number Two – Create the Deploy-Apps.ps1 script

The script uses the Parameter function to read in data from the command line and then it reads the XML file, we also need to make sure that some of the data from the XML file is parsed correctly as strings or as Boolean. Then we use all that data set some static settings and last we use the Invoke-SCScriptCommand to execute the command on the host, the script looks like this:


Step Number Three – Execute!

Execute the script like this:


And wait for the job in the log and after a while it will inform you that the job did finish with warnings, the reason for the warning is that is actually a real warning from the application that is picked up up by the output :-)

The hpsum.exe detects the version of windows as 6.2 (and that is correct), but even if HP claims that is supported, the HPSUM.exe does not have the same opinion :-). Hopefully HP will fix this later.


So in the Job log it will show up like this:


Summary using PowerShell:

This gives a more stable solution which can be extended and automated and that I like…

You can download the scripts from here:

Nice to Know – Debug Logging SCVMM 2012 SP1

Posted by Mikael Nystrom on May 10, 2013

It happens that you need to find issues, yes, trust me it happens even for me… and here is how:

To enable VMM debug logging, use the following steps:

  • Create a folder called C:\vmmlogs.
  • Open an elevated PowerShell window on the VMM server or host computer and run the following commands (the second command may wrap in your display):
logman delete VMM
logman create trace VMM -v mmddhhmm -o $env:SystemDrive\VMMlogs\VMMLog_$env:computername.ETL -cnf 01:00:00 -p Microsoft-VirtualMachineManager-Debug -nb 10 250 -bs 16 -max 512 -a
  • Start the trace by typing the following command in the elevated PowerShell window:
logman start vmm
  • Reproduce your issue.
  • As soon as you reproduce your issue, stop the trace by typing:
logman stop vmm
  • Switch to C:\vmmlogs. 
  • To convert the trace, type the command:
Netsh trace convert <filename>
  • Read file, find issue, fix, have a nice day.
