Hyper-V BSOD Windows Server 2012 R2 vhdmp.sys

On a Hyper-V server (ProLiant DL380p Gen8) that has been running for 8 months, I have suddenly had two BSOD's out of the blue ;-)

Here is the latest dump.. the only slightly different thing that has happened recently is that there is now a Windows 7 VM of SpiceWorks running as a VM
Any ideas?

  • Requirement to have 3 hyper-v in Windows Server 2012 R2 Std

    Hi,
    I want to configure three Hyper-V in my Windows Server 2012 R2 Standard.
    1. ERP System
    2. Mail Server
    3. AD
    What requirement or license do I need to have?
    Thank You.

    as per my knowledge if you want to use 3 Application you can run one application on Host and other 2 Application on virtual instances.
    that is not accurate.
    As per MS documentation, if you run two virtual instances, the host (hypervisor) may only be used for hypervisor functions, it may not be used for applications.
    http://www.microsoft.com/licensing/about-licensing/briefs/virtual-licensing.aspx
    Windows Server 2012 R2 Standard
    All physical processors need to be licensed. Each license covers up to two physical processors.
    You may run the server software in one physical OSE and in up to two virtual OSEs for each license you assign. If you run all of the permitted instances the instance in the physical OSE can only be used to manage the virtual OSEs.

  • Clustering Free Hyper-V or Windows Server 2012 Standard with Windows Server 2012 Datacenter

    Hi,
    Is anyone running a cluster which has Datacenter 2012 clustered with either Standard 2012 or Hyper-V 2012?
    I have seen posts here and elsewhere that say it is possible but when I rang Microsoft Licencing team to discuss licensing in this scenario they advised me that the hardware and OS on each clustered server must be identical.
    Now I'm really confused.
    Thanks,

  • How to import a virtual machine to a Hyper-V server by programme on Windows server 2012 ?

    Hi
    As we know, Hyper-V of Windows server 2012 can support importing a VM without exporting it first manually now.
    So I try to code a programme to do it.
    I use the method "ExportVirtualSystemEx" of  "Msvm_VirtualSystemManagementService". referenced by
    http://msdn.microsoft.com/en-us/library/dd379583(v=vs.85).aspx
    But the error said that "You can import a virtual machine only if you used Hyper-V to create and export it."
    Since we can import an unexported virtual machine in Hyper-V of windows server 2012 manually, so is there any API to support to do it by programme ?

    Hi vincent
    Thanks for your infomation. It is really useful for us.
    I 'd like to know How to adjust path ?
    When I use command 'import-vm' to import VM, I got the error "import-vm : Unable to import virtual machine due to configuration errors.  Please use Compare-VM to repair the virtual machine."
    I  try to fix this error referenced by
    http://technet.microsoft.com/en-us/library/hh848612.aspx
    I ran the commands as bellow :
    $report = compare-vm -path 'J:\HyperV\VM2008R2_1\Virtual Machines\6D2B5BF6-0BC0-4B1C-86BA-5A28DAB3DFCF.xml'

    But this web page don't mentioned how to fix the "Virtual Hard Disk file not found" error.
    and I don't want to fix the VMNetworkAdapter issue by disconnect it.
    So could you told me how to modify the virtual hard disk file path and VMNetworkAdapter to make sure that I can import the virtual machine successfully?

  • Windows Server 2012 Failover Cluster (Hyper-V) Event Id 1196

    Hi All,
    I just installed Failover Cluster for Hyper-V on windows server 2012 with 2 nodes. I got following error event id 1196.
    reCreated / deleted Cluster Host A record on DNS and nothing happened.
    Any suggestion?
    There is similar topic but it couldnt help
    http://social.technet.microsoft.com/Forums/en-US/winserverClustering/thread/2ad0afaf-8d86-4f16-b748-49bf9ac447a3/
    Regards

    Hi,
    You may refer to this article to troubleshoot this issue;
    Event ID 1196 — Network Name Resource Availability
    http://technet.microsoft.com/en-us/library/dd354022(v=WS.10).aspx
    Check the following:
    Check that on the DNS server, the record for the Network Name resource still exists. If the record was accidentally deleted, or was scavenged by the DNS server, create it again, or arrange to have a network administrator create it.
    Ensure that a valid, accessible DNS server has been specified for the indicated network adapter or adapters in the cluster.
    Check the system event log for Netlogon or DNS events that occurred near the time of the failover cluster event. Troubleshooting these events might solve the problem that prevented the clustered Network Name resource from registering the DNS name.
    For more information please refer to following MS articles:

    Hi,
    Based on your description, I do the same operation in my Lab environment (Hyper-v and Windows Server 2012). Unfortunately, this issue can’t be reappeared. So, before
    going further, would you please let me confirm something?
    Did you mean that there was no error message when this issue occurred, just the progress was stuck at 24%? How long did you wait for the change approximately? Finally,
    can the feature be installed successfully or not?
    Meanwhile, please locate to C:\ Windows\ Logs\ CBS folder and check the
    CBS log if you can find some clues.
    If anything I misunderstand or more details you can provided, please don’t hesitate to let me know.
    Hope this helps.
    Best regards,

  • Multi-Hypervisior Manager support for Windows Server 2012 R2

    Hi,
    I am attempting to connect to a Windows Server 2012 R2  Hyper-V and am getting the following error message.
    "Unable to Connect to host hyper01"
    I have tested and can connect to a Windows Server 2012 without issue.  Checking the documentation for support and whilst Windows Server 2012 is not supported I wanted to ensure I wasn't making an error.
    If it is indeed not supported at this moment, is there a viable alternative?
    Many Thanks

  • Windows Server 2012 - Hyper-V - iSCSI SAN - All Hyper-V Guests stops responding and extensive disk read/write

    We have a problem with one of our deployments of Windows Server 2012 Hyper-V with a 2 node cluster connected to a iSCSI SAN.
    Our setup:
    Hosts - Both run Windows Server 2012 Standard and are clustered.
    HP ProLiant G7, 24 GB RAM, 2 teamed NIC dedicated to Virtual Machines and Management, 2 teamed NIC dedicated to iSCSI storage. - This is the primary host and normaly all VMs run on this host.
    HP ProLiant G5, 20 GB RAM, 1 NIC dedicated to Virtual Machines and Management, 2 teamed NIC dedicated to iSCSI storage. - This is the secondary host that and is intended to be used in case of failure of the primary host.
    We have no antivirus on the hosts and the scheduled ShadowCopy (previous version of files) is switched of.
    iSCSI SAN:
    QNAP NAS TS-869 Pro, 8 INTEL SSDSA2CW160G3 160 GB i a RAID 5 with a Host Spare. 2 Teamed NIC.
    Switch:
    DLINK DGS-1210-16 - Both the network cards of the Hosts that are dedicated to the Storage and the Storage itself are connected to the same switch and nothing else is connected to this switch.
    Virtual Machines:
    3 Windows Server 2012 Standard - 1 DC, 1 FileServer, 1 Application Server.
    1 Windows Server 2008 Standard Exchange Server.
    All VMs are using dynamic disks (as recommended by Microsoft).
    Updates
    We have applied the most resent updates to the Hosts, WMs and iSCSI SAN about 3 weeks ago with no change in our problem and we continually update the setup.
    Normal operation
    Normally this setup works just fine and we see no real difference in speed in startup, file copy and processing speed in LoB applications of this setup compared to a single host with 2 10000 RPM Disks. Normal network speed is 10-200 Mbit, but occasionally
    we see speeds up to 400 Mbit/s of combined read/write for instance during file repair
    Our Problem
    Our problem is that for some reason all of the VMs stops responding or responds very slowly and you can for instance not send CTRL-ALT-DEL to a VM in the Hyper-V console, or for instance start task manager when already logged in.
    Symptoms (i.e. this happens, or does not happen, at the same time)
    I we look at resource monitor on the host then we see that there is often an extensive read from a VHDX of one of the VMs (40-60 Mbyte/s) and a combined write speed to many files in \HarddiskVolume5\System Volume Information\{<someguid and no file extension>}.
    See iamge below.
    The combined network speed to the iSCSI SAN is about 500-600 Mbit/s.
    When this happens it is usually during and after a VSS ShadowCopy backup, but has also happens during hours where no backup should be running (i.e. during daytime when the backup has finished hours ago according to the log files). There is however
    not that extensive writes to the backup file that is created on an external hard drive and this does not seem to happen during all backups (we have manually checked a few times, but it is hard to say since this error does not seem leave any traces in event
    viewer).
    We cannot find any indication that the VMs themself detect any problem and we see no increase of errors (for example storage related errors) in the eventlog inside the VMs.
    The QNAP uses about 50% processing Power on all cores.
    We see no dropped packets on the switch.
    (I have split the image to save horizontal space).
    Unable to recreate the problem / find definitive trigger
    We have not succeeded in recreating the problem manually by, for instance, running chkdsk or defrag in VM and Hosts, copy and remove large files to VMs, running CPU and Disk intensive operations inside a VM (for instance scan and repair a database file).
    Questions
    Why does all VMs stop responding and why is there such intensive Read/Writes to the iSCSI SAN?
    Could it be anything in our setup that cannot handle all the read/write requests? For instance the iSCSI SAN, the hosts, etc?
    What can we do about this? Should we use MultiPath IO instead of NIC teaming to the SAN, limit bandwith to the SAN, etc?

    Hi,
    > All VMs are using dynamic disks (as recommended by Microsoft).
    If this is a testing environment, it’s okay, but if this a production environment, it’s not recommended. Fixed VHDs are recommended for production instead of dynamically expanding or differencing VHDs.
    Hyper-V: Dynamic virtual hard disks are not recommended for virtual machines that run server workloads in a production environment
    http://technet.microsoft.com/en-us/library/ee941151(v=WS.10).aspx
    > This is the primary host and normaly all VMs run on this host.
    According to your posting, we know that you have Cluster Shared Volumes in the Hyper-V cluster, but why not distribute your VMs into two Hyper-V hosts.
    Use Cluster Shared Volumes in a Windows Server 2012 Failover Cluster
    http://technet.microsoft.com/en-us/library/jj612868.aspx
    > 2 teamed NIC dedicated to iSCSI storage.
    Use Microsoft MultiPath IO (MPIO) to manage multiple paths to iSCSI storage. Microsoft does not support teaming on network adapters that are used to connect to iSCSI-based storage devices. (At least it’s not supported until Windows Server 2008 R2. Although
    Windows Server 2012 has built-in network teaming feature, I don’t article which declare that Windows Server 2012 network teaming support iSCSI connection)

    > I have seen using MPIO suggests using different subnets, is this a requirement for using MPIO
    > or is this just a way to make sure that you do not run out of IP adressess?
    What I found is: if it is possible, isolate the iSCSI and data networks that reside on the same switch infrastructure through the use of VLANs and separate subnets. Redundant network paths from the server to the storage system via MPIO will maximize availability
    and performance. Of course you can set these two NICs in separate subnets, but I don’t think it is necessary.
    > Why should it be better to not have dedicated wireing for iSCSI and Management?
    It is recommended that the iSCSI SAN network be separated (logically or physically) from the data network workloads. This ‘best practice’ network configuration optimizes performance and reliability.
    Check that and modify cluster configuration, monitor it and give us feedback for further troubleshooting.

  • VMM Agent install fails on Windows Server 2012 R2 Hyper-V

    Hi,
    We are unable to install VMM 2012 R2 agent on Windows Server 2012 R2 server either from VMM console or manually on the hyper-v server.
    Error on VMM Console:
    Error (410)
    Agent installation failed on chsicoecdh03.casper.com.
    Fatal error during installation (0x80070643)
    Recommended Action
    Try the operation again. If the problem persists, install the agent locally and then add the managed computer.
    ==================================================================
    Error on Hyper-v server:
    MSI (c) (E8:D0) [16:53:24:726]: Windows Installer installed the product. Product Name: Microsoft System Center Virtual Machine Manager Agent (x64). Product Version: 3.2.7510.0. Product Language: 1033. Manufacturer: Microsoft Corporation. Installation success
    or error status: 1603.
    Also, I suspect may be issue with WMI then checked WMI repository and it is in consistent state. winmgmt /verifyrepository.
    Please help on this issue.
    Any help would be appreciated.
    Thanks

    So, I've managed to research this some more since Thursday and I've come to the conclusion that Hyper-V does a horrible job of supporting Qualcomm NIC cards. That's the only thing I can conclude as far as where the issue is originating. I've read many
    post and walkthroughs but nothing that has helped. The issue wasn't with any settings in the domain controller. The issue was that there really is a slow connection originating at the domain controller that is a VM and has network connectivity through the
    virtual switch from Hyper-V. So, next question is, how do I get the DC to have better connectivity through the NIC that Hyper-V won't give it? If hyper-v would allow passthrough, this would be so much simpler. VM-ware is looking really good at this point.
    Im disappointed in MS right now.

  • Windows Server 2012 Hyper-V network latencies

    Hi All,
    I have an issue with our Windows Server 2012 Hyper-V hosts that I can't seem to figure out. Situation:
    2 x Dell PowerEdge R815 servers with AMD opteron 6376 16 core CPU's and 128 GB RAM running Windows Server 2012 with Hyper-V.
    2 virtual machines running on the same physical host and connected to the same virtual switch show high TCP connection latencies. One virtual machines runs a SQL Server 2012 database instance and a Dynamics AX 2012 R2 instance. The other machine a
    SharePoint 2013 instance and the AX client. We see latencies of 20ms and higher on most of the TCP connections that are made from the sharepoint machine to the sql server machine.
    At first I thought it might have something to do with the physical NIC's. It turned out that VMQ wasn't correctly supported by the firmware of the Broadcom BCM5709c cards. By default this setting is enabled. Turning off the VMQ setting somewhat improved
    the situation but the latencies are still at 8ms and higher.
    What I don't understand is what influence enabling/disabling VMQ should have on network performance. As I understand it now virtual machines connected to the same virtual switch bypass the physical altogether. Another point is that VMQ should actually improve
    performance, not decrease it.
    Another question I have is about the various tcp offloading settings on the physical NIC's. After installing the new firmware and drivers from Dell most of these settings are set to disabled. The documents I have been able to find talk about Windows Server
    2008, any thought how these settings relate to Windows Server 2012 and whether they should be enabled?
    Thanks in advance for your time and thoughts
    Kind regards,
    Dennes Schuitema

    Hi Denes,
    Please try to update your BroadCom NIC driver version ,the newest version should be 7.8.51

  • Storport.sys BSOD on Windows Server 2012 R2

    I recently purchased a Server that houses 45 4TB drives to use as my backup to disk solution. I installed Windows Server 2012 R2 Standard so that I could take advantage of Microsoft's Storage Spaces. I have configured the Storage Pool
    with Dual Parity with 3 hot spares. I have also updated every thing to the most current firmware, drivers and Windows Updates that I could find but I am still getting the BSOD. I am using Symantec Backup Exec 2010 R3 to backup my file server to this server.
    It will run for anywhere between 12 to 31 hours transferring 1.5 to 3TB and then my server will Blue Screen and every time it Blue Screens it says it is caused by the storport.sys Driver. I've found articles talking about the storport.sys driver causing nonpaged
    pool leaks but that was for Windows Server 2008 R2, I can't find anything for Windows Server 2012 R2. If you need additional information just let me know and I will provide it. Any help you can give would be greatly appreciated.

    Hi,
    This article provided the limitation of Storage Pool in Windows Server 2012 R2:
    https://social.technet.microsoft.com/wiki/contents/articles/11382.storage-spaces-frequently-asked-questions-faq.aspx#What_are_the_recommended_configuration_limits
    Yor current situation is still in supported configuration.
    Also there is no hotfix for Windows Server 2012 R2 regarding storport.sys yet. Which means your current issue is not a known issue.
    For further troubleshooting purpose you may need to collect dump files for analysis. However it will take a long time to do the troubleshooting process on forum. Thus it is recommended to submit a ticket to Microsoft online support for a professional troubleshooting.
    To obtain the phone numbers for specific technology request please take a look at the web site listed below:

  • Windows Domain Controller on Windows Server 2012 R2: Hyper-V roaming profiles not loading due to slow connection

    I have racked my brain and done everything that I know to do for about two weeks now.  I am setting up a new system at our fire department and I am having the worst luck with getting the workstations to login to the domain controller with roaming
    profiles.  It keeps telling me that the roaming profile could not be loaded because of a slow connection.  These are workstations that are connected directly to the switch that the DC is connected to.  I have tried multiple connections regarding
    the layout (DC into the router, router into the switch).  The router is a Cisco RV220W.  I have two VLANS, one for public and one for private domain.  The Private VLAN has DHCP turned off since I am providing it through the DC.  I currently
    have a connection from the Private VLAN going to the unmanaged switch that the workstations and server are plugged into.
    The server is a Dell PowerEdge R420 that has 6 NIC ports (1 dual port and 1 quad port).  I have a virtual switch setup on Hyper-V for an external port (let's say Card 2 Port 3) that is assigned to the WS 2012R2 Domain Controller.  The DC can see
    the internet fine and the workstations can connect to the shared folders on the server.  I can retrieve files by just using the computer name or FQDN.  The DC is also running DNS and DHCP.  The DNS has the _msdcs setup from when I installed
    the active directory role.  I have attempted to assign static IP addresses to the workstations:
    IP:                     10.0.0.80
    Subnet:             255.255.255.0
    IPV4 Gateway:  10.0.0.1
    IPV4 DNS:        10.0.0.12
    I've attempted "append the specific DNS suffix", I've "registered the connection in DNS", I've used "use this connections suffix in DNS registration".
    The server is assigned:
    IP:                     10.0.0.12
    Subnet:             255.255.255.0
    IPV4 Gateway:  10.0.0.1
    IPV4 DNS:         10.0.0.12
    The DNS entries have forwarders that forward to my ISP DNS servers for lookup
    I've enabled and disabled DHCP, I've installed a new VM just to create another DC to make sure that I didn't goof up when I created it.
    I've lost my patience with this project and am sinking fast.  Can someone please offer some advice as to what I've done wrong?  I've created this exact scenario at work many times but, I've never done it with Windows Server 2012.  Is this
    possibly something to do with the Dell PowerEdge server (Generation 12) with the SR-IOV?  I am going to attempt to work on it some more tomorrow when I get over there.  I think there may be an issue with the SR-IOV not being enabled on the machine
    through the Dell Bios.  Would the SR-IOV really cause the workstations to report a slow connection?  When I login at the domain controller the roaming profiles and folder redirection work fine so, I know the GPO settings are correct.  I don't
    have "ignore slow connections" or any of those GPO's set.  I need to get it working the correct way so, I didn't want to fool the server when there is another underlying problem.  Any help that someone can offer, I am more than willing
    to listen.  If you need more information, please ask.
    Thanks,
    Jay

    It is not a bug, you might be using IE in Windows server 2012 and and browser might be restricting your site actions to respond properly.
    Check this in a different browser or access site in a differ OS.

  • Is it possible to install SQL Server 2012 Standard Edition on a Windows Server 2012 Standard Which is installed on a Virtual Machine that is created by Hyper-V?

    Hi
    I have recently bought a Virtual Machine from a data center and installed a Windows Server 2012 Standard Edition on it. As I tried to install the SQL Server 2012 Standard Edition, the data center administrator denied me to do this telling me it is not possible
    to install any licensed Microsoft software on a Windows installed on virtual machine created by Hyper-V. It was really strange for me! I wanna know if this is true.
    Thanks Everybody

    Hi Farid,
    For SQL server running on virtual server please refer to following article :

  • (Request for:) Best practices for setting up a new Windows Server 2012 r2 Hyper-V Virtualized AD DC

    Could you please share your best practices for setting up a new Windows Server 2012 r2 Hyper-V Virtualized AD DC, that will be running on a new WinSrv 2012 r2 host server.   (This
    will be for a brand new network setup, new forest, domain, etc.)
    Specifically, your best practices regarding:
    the sizing of non virtual and virtual volumes/partitions/drives,  
    the use of sysvol, logs, & data volumes/drives on hosts & guests,
    RAID levels for the host and the guest(s),  
    IDE vs SCSI and drivers both non virtual and virtual and the booting there of,  
    disk caching settings on both host and guests.  
    Thanks so much for any information you can share.

    A bit of non essential additional info:
    We are small to midrange school district who, after close to 20 years on Novell networks, have decided to design and create a new Microsoft network and migrate all of our data and services
    over to the new infrastructure .   We are planning on rolling out 2012 r2 servers with as much Hyper-v virtualization as possible.
    During the last few weeks we have been able to find most of the information we need to undergo this project, and most of the information was pretty solid with little ambiguity, except for
    information regarding virtualizing the DCs, which as been a bit inconsistent.
    Yes, we have read all the documents that most of these posts tend point to, but found some, if not most are still are referring to performing this under Srvr 2008 r2, and haven’t really
    seen all that much on Srvr2012 r2.
    We have read these and others:
    Introduction to Active Directory Domain Services (AD DS) Virtualization (Level 100), 
    Virtualized Domain Controller Technical Reference (Level 300),
    Virtualized Domain Controller Cloning Test Guidance for Application Vendors,
    Support for using Hyper-V Replica for virtualized domain controllers.
    Again, thanks for any information, best practices, cookie cutter or otherwise that you can share.
    Chas.
