Windows 8 Hyper-V - Virtual Machine Management Service failed to start the virtual machine

I have Hyper-v running on Dell Precision T3600 with Windows 8 OS.  I am trying to start a VM (called Windows8VM) to install Windows 8 in the hyper-v virtual machine, but I keep getting the following message:
"Windows8VM" failed to start.
Failed to start the virtual machine "Windows8VM" because one of the Hyper-V components is not running.
"Windows8VM" failed to start.  (Virtual machine ID D670D3BB-9AE2-0453D-9191-EA6EFC242A9C)
The Virtual Machine Management Services failed to start the virtual machine "Windows8VM" because one of the Hyper-V components is not running.
I have turned the hyper-v feature on in the "Turn Windows feature on or off.  The BIOS has virtualization enable.  Help!!! driving me nuts for a week now.
Nick :(

Okay,  I turned off hyper-v, went to bios and enabled Intel TXT(LT-SX) Configuration.  Made sure that both Virtualization and VT for Direct I/0 are on.  Next, I turned on Hyper-V and I create a brand new Virtual Machine call Windows8 and had
the DVD point to Windows8 ISO file on hard drive.  When I clicked on start, it stayed in the Starting status mode for about 5 minutes.  Then of course it failed.  I looked at the Hyper-V-VMMS log and here is what it output:
Log Name: Microsoft-Windows-Hyper-V-VMMS/Admin

  • Hyper-V - 'Failed to start the virtual machine 'test' because one of the Hyper-V components is not running.'

    Hi all,
    Having a bit of a nightmare with Hyper-V on my Windows 8 Pro laptop - Whenever I create a new VM and try to start it I receive the following error;
    'Failed to start the virtual machine 'test' because one of the Hyper-V components is not running.'
    I sometimes also receive an error saying something along the lines of 'Unable to change virtual machine state'
    I have done a lot of searching a seen two common answers - The first is to try removing the Hyper-V role and re-adding it - I have tried this several times to no avail. (Intel VT and all virtualisation capabilities are enabled in BIOS). The second issue
    it would seem
    some people have had relates to editing the VMX configuration file and adding the line
    hypervisor.cpuid.v0 = "FALSE" - I thought VMX files were only present in VMware Virtual Machines...
    Any help would be greatly appreciated.
    Many thanks in advance.
    James

    The hypervisor event log message is generated only at boot - so this would be expected.  Also vmbus should not be running on the host (I was looking at a VM yesterday)...  This error message is generated only when the vid is determined not to be
    running or cannot communicate with the hypervisor.
    I have seen this due to anti-virus software in the past or due to driver verifier being configured.  Since it looks like you checked driver verifier already do you have anti-virus software installed?  If so have you followed the best practices
    and exempted the Hyper-v services?

    To resolve this problem, configure the real-time scanning component within your antivirus software to exclude the following directories and files:
    Default virtual machine configuration directory (C:\ProgramData\Microsoft\Windows\Hyper-V)
    Custom virtual machine configuration directories
    Default virtual hard disk drive directory (C:\Users\Public\Documents\Hyper-V\Virtual Hard Disks)
    Custom virtual hard disk drive directories
    Custom replication data directories, if you are using Hyper-V Replica
    Snapshot directories
    Vmms.exe (Note: This file may have to be configured as a process exclusion within the antivirus software.)

  • Vritual Fibel adapter failed to start the Virtual Machine

    Hi All,
    I have installed windows server 2012 R2 RTM with Hyper-V. I have created virtual machine with virtual fiber channel adapter connected to physical one. When I start the virtual machine it gets failed to start and the following error occurs.
    Thanks,

    take a lool on that
    http://social.technet.microsoft.com/wiki/contents/articles/18698.hyper-v-virtual-fibre-channel-troubleshooting-guide.aspx
    I guess also that some Part of the Chain do not Support all needed Settings like NPIV.
    dealing with vFC inside a Guest ist really tricky and following Support Matrix is really key, it starts on the FCP SAN Array and Ends up having the latest Hotfixes regarding vFC Problems. Between you need to have all Setup right and supported Drivers,
    FW and so on.
    In my view using this Feature you loss the my most Importent Sexy Thing why i do Virtualisation ? beeing seperate from the HW Layer.

    Hi mish11mish11,
    Lets see if we can get that working again. If you are having issues with the Apple Mobile Device Service you may need to just restart the service. Check out the first article to walk you through that process. If you are still having issues, take a look at the second article to continue your troubleshooting.

  • Windows 10 Technical Preview - There is NO "Hyper-v Virtual Machine Management" service???

    hi all,
    There's no such Windows Topic as "WTP Virtualization", so I post this thread here, a somewhat "VIRTULIZATION" related.
    I installed WTP (not server) x64 enterprise 9879, and added "Hyper-v Management" feature (management only, without Hyper-v core) in Control Panel. Then I found that there was no "Hyper-v
    Virtual Machine Management" in Services panel, and there was no such file "c:\windows\system32\vmms.exe". Therefore I cannot connect to Windows Server 2012 R2 Hyper-v through WTP Hyper-v Manager.
    I confirm the reason is what I state above. Firewall rules are properly configured on both Hyper-v server and WTP. I also used hvxxxx.wsf to configre anondcom to be "allow". When
    I connect WS 2012 R2 through WTP, Hyper-v manager on WTP says "Please confirm VMMS server is running".
    Is it a bug, or lack of implementation, or restriction of preview edition?
    Any suggestion is appreciated! Thanks!

    Okay,  I turned off hyper-v, went to bios and enabled Intel TXT(LT-SX) Configuration.  Made sure that both Virtualization and VT for Direct I/0 are on.  Next, I turned on Hyper-V and I create a brand new Virtual Machine call Windows8 and had

  • Windows Server 2012 Standard - Remote Desktop Management service won't start

    Dear colleges, I'm seeking your help in resolving a weird issue with Remote Desktop.
    The Remote Desktop Management service gives the following error message any  time it is attempted to start:
    "The Remote Management Service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other services or programs."
    The Event Viewer error message is as follows:
    "The Remote Desktop Management service failed to start. Error code: 0x88250001"
    Whenever I connect to the server with RD I get error message that the Remote Desktop Licensing Server isn't configured and that the RD trill will expire in N-days. The server is up to date updates wise and has been licensed for 5 RD CALs. The server hosts DNS
    server and has AD DS role installed, is virtualized to have one Hyper-V server.
    I read some blogs about having both DNS and AD DS on one box is a bad sea and a root cause of the issue. Well, that very well may be, but for me that's an option as I'm not going to get a box to just host DNS. There should a solution to this as I shouldn't
    only one suffering from this issue.
    I also read about KB2871777 - Servicing stack update supposedly addressign this issue. Well, it's on my system and the issue is there too. :)
    Will I loose ability to RD when the trial expires or it's just another misleading MS message that can be ignored?
    How do I mend Remote Desktop Management service to start?
    Appreciate your help!
     

    Hi,
    Thank you for posting in Windows Server forum.
    Can administrators perfectly connect to RDS environment?
     In meantime please check that you have properly configured and activated RD License role service and install RDS CAL on it. It might also possible that you have configured RD License server but it server can’t find it and giving you error due to certificate
    also. Please check that you have properly configured certificate on your RDS Server. Try to install and update below hotfix for License related issue.
    No RDS license when you connect to an RDS farm in Windows Server 2012
    http://support.microsoft.com/kb/2916846
    If you have configured both RDS and AD DS on single server then also you may find some error reading this. If so please try to setup both roles on different server and check the result. In addition to this, please check below articles.

  • Remote Management service does not start

    Has Novell got a fix for the issue where the Remote Management services
    fails to start automatically on XP workstations? As we upgrade our clients
    to XP, this has become a major headache. The service can be started
    manually, and then the Remote Control feature of ZFD will work, providing
    the firewall is disabled.

    Workaround is to create a batch file and put in the command:
    net start "remote management"
    Create a shortcut to this batch file and put it in the startup group of
    All Users in the "document and settings".

  • Please Help - "iPod service failed to start...."

    I have an iPod mini. I have Windows XP. I needed to upgrade my iTunes to get a song I really wanted. And this is what happened...
    -It was 'registering iPod service and a window pops up and says "Could not start service"
    -I hit "OK"
    -After a minute or two, a window pops up and says 'iPod service failed to start. Verify that you have sufficiant privileges to start system services'
    What do I Do?
    iPod Mini   Windows XP  

    it then said "Could not update environment variable 'PATH'. Verify that you have sufficient privilages to modify environment variables."
    that's fairly exotic on a 7.0.x install. (for some reason there have been all manner of kinky error messages showing up for folks over the last couple of days. i'm having to say "exotic" a lot.)
    okay, let's try working through the general troubleshooting advice from the following document:
    Trouble installing iTunes or QuickTime software in Windows
    ... but if no joy there, let's get an itunes 7 installer log to the Apple engineers for a look.
    1. Open a command prompt window. (Start menu -> Run. Type in "cmd". Hit return.)
    2. Drag and drop iTunesSetup.exe onto the window so that the full pathname of the file is at the command line prompt.
    3. Type in a space, then the following line:
    /l*v C:\log.txt
    4. Hit return.
    5. The installer will create a log file:
    C:\log.txt
    Find that file and send it as an attachment to this email address.
    in the email to Roy, be sure to include the following information:
    - A link to the thread on Apple Discussions where the issue is being discussed
    - The username you are using in the thread
    - The version of iTunes you are using or trying to use
    - the version of Windows you are using (mention service packs)
    - A concise description of the issue you are seeing
    - The exact text of the error message you are seeing

    Hi Michael,
    The above errors indicate the following two things:
    1. An existing service is using port 64337.
    2. Port 64337 is blocked by firewall.
    I recommend you use the commands below to check if port 64337 is used by a program.
    netstat -aon | findstr "64337"
    tasklist | findstr "64337"

  • Error Creating VM on 2011 iMac - The Hyper-V Virtual Machine Management service encountered an unexpected error: The remote procedure call failed. (0x800706BE).

    I am running Hyper-V in Windows 8.1 on a late 2011 27 inch iMac. Whenever I try to create a virtual machine I get the error below and Windows warns that it will restart in 1 minute. I tried a clean install of Windows, but my PC still crashes ever

    Hi CharlesPool,
    I am assuming that the win8.1 is in-place updated from win8 .
    Maybe you need to check the state of hypervisorlaunchtype .
    If it is off , please run command " bcdedit /set hypervisorlaunchtype auto "

  • The hyper-v virtual machine management service encountered an unexpected error logon failure 0x80070569

    I dont understand why Microsoft people can't make things simpler
    They are LITERALLY MOTHER F%^%RS
    Bill Gate and his team need to learn hot to F^&&IN make things.

    I agree, the use of profanity is completely unnecessary, we've all been in the stressful situation before, it still doesn't call for it.
    The network you're receiving an APIPA IP on, is it the virtual switch you setup when adding the Hyper-V role?  If so you can get the warnings to go away and subsequently hide the adapter by unchecking the 'Allow host to manage this adapter' setting
    in the virtual network manager of Hyper-V manager on each node.
    Tim is also right, while disk resources are only owned by one node, you'll see the mount points for CSVs located under C:\ClusterStorage.
    More importantly, you're logon issue sounds directly related to group policy.  I had the same problem moving to Server 2012.  Yes, it's an annoying process but in the end you will have a working cluster.  I did the following steps:
    1. Install 'Group Policy Manager' on one of the nodes in your Hyper-V cluster
    2. Log on to the node you installed it on with a Domain Admin or appropriately endowed account that can edit the GPO relating to 'Logon as a service right'
    3. Edit the GPO where you specify who can logon as a server, OR if you don't have one, make a new one and link it to the OU with the Hyper-V nodes
    4. Add permission to that right for 'NT Virtual Machine\Virtual Machine Group', save and exit
    5. As an optional step I would reboot the nodes so you make sure they get it
    The problem here is that security group ONLY exists on servers that have Hyper-V installed on them.  If you add the group on a machine that has it to the GPO, the SID for the group is saved and each Hyper-V host will know what group that is.  The
    problem you're having right now is most likely related to a GPO changing 'Logon as a service right' to your needs and setup in Group Policy.  When a Hyper-V node starts up, it automatically adds the right for that group to the local security policy, however,
    group policy's auto refresh will remove it after a certain amount of time.

  • Cant create replica and Hyper V virtual machine management service slow shutting down

    Hi,
    I cant create replica and Hyper V, I go through the process and all looks good it even starts to create the hard disk but it stops at 4096K and the wizard just keeps going.
    The management console is also slow or wont load virtual machines - stuck on loading virtual machines
    The Hyper V virtual machine management service slow shutting down over 30 minutes on re boot of Hyper V core 2012 R2
    Any ideas ?

    Hi Sir,
    I assume that you have a standalone hyper-v server 2012R2 and you are using hyper-v manager to manage the hyper-v host .
    Which system you are using to manage hyper-v host , win8 or win8.1 or other ?
    Have you created VMs on the HOST ?
    I would suggest  you to create vhd or someother operation on hyper-v host directly  to check the result .
    Best Regards

  • When I download itunes, it says that Ipod Service failed to start. I checked the services under task manager and when I try to start it, it says access denied. How to I get access and for the ipod service to start and run?

    Please help. My ipod classic could not be recognised by itunes when I connect my ipod to PC. Previously it has been recognised before I updated. This was a while ago now and so I removed all apple files and re installed the latest itunes but am having the same problem.
    When I download itunes, it says that Ipod Service failed to start. I checked the services under task manager and when I try to start it, it says access denied. How to I get access and for the ipod service to start and run?

    Some anti-virus programs (e.g., McAfee) have this rule that can be invoked under the "maximum protection" settings: PREVENT PROGRAMS REGISTERING AS A SERVICE. If that rule is set to BLOCK, then any attempt to install or upgrade iTunes will fail with an "iPod service failed to start" message.
    If you are getting this problem with iTunes, check to see if your anti-virus has this setting and unset it, at least for as long as the iTunes install requires. Exactly how to find the rule and turn it on and off will vary, depending upon your anti-malware software. However, if your anti-virus or anti-malware software produces a log of its activities, examining the log may help you find the problem.
    For example, here's the log entry for McAfee:
    9/23/2009 3:18:45 PM Blocked by Access Protection rule NT AUTHORITY\SYSTEM C:\WINDOWS\system32\services.exe \REGISTRY\MACHINE\SYSTEM\ControlSet001\Services\iPod Service Common Maximum Protection:Prevent programs registering as a service Action blocked : Create
    Note that the log says "Common Maximum Protection: Prevent programs registering as a service". The "Common Maximum Protection" is the location of the rule, "Prevent programs registering as a service" is the rule. I used that information to track down the location in the McAfee VirusScan Console where I could turn the rule off.
    After I made the change, iTunes installed without complaint.

  • Why would you use a managed service account rather than a virtual account in SQL Server 2012?

    In SQL Server 2012, service accounts are created as
    virtual accounts (VAs), as described
    here, as opposed to
    managed service accounts (MSAs).
    The important differences I can see for these, based on the descriptions:
    MSAs are domain accounts, VAs are local accounts
    MSAs use automagic password management handled by AD, VAs have no passwords
    in a Kerberos context, MSAs register SPNs automatically, VAs do not
    Are there any other differences? If Kerberos is not in use, why would a DBA ever prefer an MSA?
    UPDATE:
    Another user has noted a
    possible contradiction in the MS docs concerning VAs:
    The virtual account is auto-managed, and the virtual account can access the network
    in a domain environment.
    versus
    Virtual accounts cannot be authenticated to a remote location. All virtual accounts
    use the permission of machine account. Provision the machine account in the format
    <domain_name>\<computer_name>$.
    What is the "machine account"? How/when/why does it get "provisioned"? What is the difference between "accessing the network in a domain environment" and "authenticating to a remote location [in a domain environment]"?

    Hi,
    “Virtual accounts cannot be authenticated to a remote location. All virtual accounts use the permission of machine account. Provision the machine account in the format <domain_name>\<computer_name>$.”
    “The virtual account is auto-managed, and the virtual account can access the network in a domain environment. If the default value is used for the service accounts during SQL Server setup on Windows Server 2008 R2 or Windows 7, a virtual account
    using the instance name as the service name is used, in the format NT SERVICE\<SERVICENAME>”
    Per the above description, they are two concepts and not conflict with each other.
    As you understand, virtual account access network resources by using the credentials of the computer account. Generally, computer account will not be granted permission unless giving the computer account permission on the shared folder manually.
    Thanks.
