I am experiencing an issue when I removed the Wireless device and then re-installed it on Hyper-V Windows 8.

The error states : "Failed while modifying virtual Ethernet Switch connection settings" followed by "Ethernet port {f...} bind failed unspecified error (0x80004005)"

Is anyone else experiencing this kind of issue?

Unable to remove Hyper-V role from Windows Server 2008 R2 Standard server

Hello world,

An attempted removal of the Hyper-V role on a Windows Server 2008 R2 Standard server has failed (on an HP ProLiant DL380 G6), resulting in Hyper-V showing up in Server Manager in some half-dead state. Hyper-V services aren't running (they've been removed) but something (Hyper-V-VMMS) is alive enough to still put events in the Event Log.

If I attempt to remove the Hyper-V role now, it whirrs away for a minute and asks for a reboot. Once the machine has started, the clean-up that automatically launches just asks for a reboot again. This happens until the OS gives up (i.e. Windows *detects* that it's stuck in an infinite loop).

Looking in the ServerManager.log file (what is it with these stonkingly massive log files? I quite like using Notepad, you know!) I suspect this is what's tripping the uninstall up:

5400: 2012-11-06 13:22:34.758 [Services] Error (Id=0) System.InvalidOperationException: Service vhdsvc was not found on computer 'DR-SRV-SQL1'. --- System.ComponentModel.Win32Exception: The specified service does not exist as an installed service --- End of inner exception stack trace --- at System.ServiceProcess.ServiceController.GenerateNames() at System.ServiceProcess.ServiceController.get_DisplayName() at Microsoft.Windows.ServerManager.ServiceInfo.InitServiceInfo(Object obj)

5400: 2012-11-06 13:22:34.758 [Services] Error (Id=0) System.InvalidOperationException: Service nvspwmi was not found on computer 'DR-SRV-SQL1'. --- System.ComponentModel.Win32Exception: The specified service does not exist as an installed service --- End of inner exception stack trace --- at System.ServiceProcess.ServiceController.GenerateNames() at System.ServiceProcess.ServiceController.get_DisplayName() at Microsoft.Windows.ServerManager.ServiceInfo.InitServiceInfo(Object obj)

5400: 2012-11-06 13:22:34.758 [Services] Error (Id=0) System.InvalidOperationException: Service vmms was not found on computer 'DR-SRV-SQL1'. --- System.ComponentModel.Win32Exception: The specified service does not exist as an installed service --- End of inner exception stack trace --- at System.ServiceProcess.ServiceController.GenerateNames() at System.ServiceProcess.ServiceController.get_DisplayName() at Microsoft.Windows.ServerManager.ServiceInfo.InitServiceInfo(Object obj)

It's like it's trying to remove Hyper-V services that are simply no longer there and can't handle the fact. Is there any way to mop up the bits the Hyper-V role removal can't get to, or is the ghost of Hyper-V in Server Manager nothing much to worry about now?

I seem to be stuck between two choices here: leave the server as is and just let Hyper-V hang around like some dead conjoined twin, or undertake the perfect ((insert opposite of heaven here)) that is reinstalling Windows on a three year old server. Neither are terribly appetising!

Any help, tips or pointers would be appreciated!

Thanks in advance,

Paul C

Hi there,

 

I am trying to increase the display resolution to 1600x1050 for my virual server (Hyper-v), but the max I can get is 1280x1024.

I installed the Integration services and all the updates for the host os (win 2008 Enterprise) and guest os (win 2003 R2 Enterprise).

 

any idea?

 

Thanks,

I have a new server and need some advice on the best way to configure it.  Here is what I have

Dell T420

2 6-core Intel CPUs

T710 Raid Controller

4x1tb SAS drives

32gb RAM

2 NIC

I want to install Server 2012 with a Hyper-V role.  I then want to install 2 virtuals (SBS2011 and Server2008R2 with RDS role installed).  What is the best way to configure all of this on this physical box?

1. In the T710 controller would it be best to configure 1 300gb VD and 1 2700gb VD (RAID 5) and then install the Server 2012 using the 300gb boot and then 2700gb in an extended D: drive then..... install the SBS2011 and Server 2008R2 VHDs on this D: partition?

2. How best to configure the memory for the 2 virtuals?  Same goes for virtual processors in the virtuals.

3. Would it be worth it to put in 2 more 1tb drives and make them their on VD in the controller used for the Server 2012 boot that way I can leave the entire 3tb VD as an extended?

4. Since I have 2 NICS would it be best to dedicate 1 NIC to the Server 2012 and the other NIC to both of my virtuals?  I know the SBS2011 will get 98% of the activity with the Server 2008 R2 RDS getting a few users a day with limited activity.

Thanks and any other advice would be welcome.  This is my 1st foray into Hyper-V.

Hyper-V guest system caused NIC connectivity issue

I am doing a forensics investigation into an error that occurred on our Host Hyper-V Server. 

A Domain Controller running W2K8 w/ SP and using Hyper-V lost its network connectivity so that I could not access the DC via RDP (network connectivity was lost). The only method of gaining access to the DC was via KVM attached to the box.

This seemed to occur because of the virtual NIC used by Hyper-V Network Manager.  When I removed the Network Manager for the Hyper-V server, connectivity was restored (after a DNS refresh).

Before I build a new Net Mgr and deploy it on the DC (Host server), I'd like to understand what happened so as to prevent this issue from occurring again.  Any ideas?

Thanks, Jesse

I have setup a lab and have two machines:

1. Windows 8 PC with RSAT installed

2. A machine with the hyper-v server 2012 installed and "configured"

After a very painful and difficult setup process for the two PC's to trust each other (not in domain, standalones), I am able to remotely manage the hyper-v box from my Windows 8 computer (I spent hours searching for information to get this working -- come on Microsoft!!).  However, I have a QNAP device configured on the network and I want to add it by iSCSI.  I went to 'Add Roles and Features Wizard' and checked 'File and iSCSI Services', 'File Server' and 'Storage Services' and hit install.  I then rebooted the server.  When I go to Server Manager via RSAT, and go to iSCSI, it tells me I need to install the iSCSI Target Server role service and to go to Roles and Features wizard.  This I have done and if there is a piece that is missing, I do not see the checkbox to enable it.  Any ideas?

I also tried from the powershell end and ran the install commands to install iSCSI portion but powershell tells me that it does not exist(The extent of my powershell knowledge is what I find by doing searches).  It would appear that I am missing features on the hyper-v server 2012 -- are there pieces that I need to download and install to get this working?  If so, where can I find this information?  There is very little information out there for W8 to hyper-v 2012. (my end goal is to install a server 2012 as a VM using the QNAP as storage, then I can promote that server to DC and then join everything to it.)

I appreciate any assistance.

Hyper-V replica over dedicated network

Hi,

I just setup a couple of Windows Server 2012 Hyper-V boxes and enabled the replica of a VM. All seems to work fine. These 2 boxes are connected to corporate LAN through a NIC and each other through a crossover cable over another NIC. As I can see, the replica trafic flows through corporate LAN. I'm trying to move it over the crossover lan, to save corporate bandwith for VMs, but I can't figure out how. I tryed to setup the replica using the IP address of the "crossed lan", but in this case the replica setup fails with a kerberos error (maybe because that lan is detected as public and not as a domain one). I've not tryed with certificate authentication, but this seems to me quite cumbersome considering that both servers are members of the same domain (Kerberos seems the smarter choice).

Has anyone ever tryed this kind of configuration ? What's the best thing to do ?

Thanks a lot.

Massimo Piceni.

I have a windows server 2012 with hyper-v added as a feature. I have created a server 2012 and a windows 8 guest machines. The windows 8 machine has internet connectivity and can successfully be added to our AD domain. I can log in to the domain on this guest machine with an AD account. However the server 2012 guest machine cannot be joined to the domain and does not have internet connectivity. Strangely enough (to me!). Is there any special settings/config that I should be doing/have missed?!

Hyper-V 2012 host freezing hard

I have a test platform, which is based on a consumer mainboard and Intel Core i3 CPU. Changing it is not a choice.

This one worked wonderful with Server 2008 R2, including the Hyper-V role. Until I tried to install Server 2012 as upgrade. At first reboot during the installation the system stopped with the single window logo on screen - and only a rollback could bring the machine up again.

Ok, incompatibilities with old drivers or such I thought and performed a clean install. This went well. System was performing great and only waiting to get its jobs. But after adding the Hyper-V role the following reboot again ended in a frozen startup logo. Only safe mode is still working, but an attempt to remove the Hyper-V role from here failed (the wizard did not move on after unselecting the role).

So now I have a useless Server 2012 machine and the choice to go back to Windows Server 2008 R2 or find a way to get Server 2012 up and running again on the platform - with Hyper-V.

Any ideas what is causing the behavior and how to fix it?

Best greetings from Germany

I have a problem where about every 2 days or so, my host operating system blue screens with a "Memory Management" error. I have run the memory diagnostics on the system and manully set the timings on my RAM, everything checks out OK. All RAM sticks are matched with the same model and speeds. The host is Windows Server 2008 Standard RTM x64.

I'm trying to remotely manage a server core installation with Hyper-V Manager but whenever I try to create or import a VM, the remote file browser comes up empty and just says 'No items match your search'.

What's strange is that this seems to work fine if I connect to the 2012 server from my Windows 7 desktop or a 2008R2 server but fails if I'm connecting from a Windows 8 system or another 2012 server.

I'm also fairly certain that this was working from a remote 2012 server until I installed the server-gui-mgmt-infra feature on the Hyper-V server but I'll need to reload the server to confirm that. (uninstalling the feature didn't fix the problem so it may not be related)

Is there any good documentation on understanding/troubleshooting remote file browsing or has anyone experienced this before?

I have built & configured a Hyper-V 2012 server.  It's connected up to a EMC VNX5300, through which I have presented the server a 1TB line.  When I use comp mgmt to connect to the server to provision the space, I see it presented as two separate 1TB drives, & I'm unable to bring them online.  I know I need the storage drivers, but I'm not able to find the download.

Hi!

Hyper-V on 2012.

I've got a Ubuntu, 12.10, server installation which i try to add some storage to. I've created 64GB harddrive (VHDX) as the 1st drive. And then a 2nd drive 4TB (VHDX). Thin.prov on both.

Creating and formating: Using gdisk, parted or gparted (livecd) on ubuntu I'm not able to partition, GPT, and initiate a filesystem on the the large VHDX.

Is there a problem with Hyper-V 2012 and drives (VHDX) >2TB when used by guests?

Edit: :) Typo in title... Ubunut...

Hi,

We are using Hyper-V replication in our environment.

I was wondering if it is possible to separate the .hrl (Hyper-V Replication Log) to another location (other set of disks), than the vhdx?

Also, if you can tell me how we can achieve that, it will be great.

Thank you!

We have two Windows Server 2012 Servers running Hyper V with about 10 virtual machines each.  Every day the Hyper V manager service stops for no reason. We do not have Virtual Machine Manager in our environment (saw an article about this).  What in the world could be causing this?

I have a AMD Athlon II x64 635 CPU which according to this site, has RVI for Hyper-V.  My mobo is a MSI 785GM-P45.  My video card is a ATI HD 4200.

Before I had Hyper-V running, my server did have AD on it but once I setup Hyper-V, I transferred all the roles to a Virtual DC and removed AD off my server.

When I add the RemoteFX role to the server and reboot, My hyper V settings page hang up.  I haven't seen any other solutions other than checking the GPO for the logon message, which I am not using.

Coreinfo shows that I do have the options but I am also running it against the Hypervisor since it's already configured.

I am not seeing anything in the logs but I could have missed something.

I have a feeling there is a piece of the AD role left behind which Hyper-V is seeing and thus freezing up.

Can anyone suggest anything?

Hi guys:

I got a  problem . When I start the 40 VMs at the same time , the server almost  dead , after 35 minutes, all VMs start success.

There are my server hardware info:

1,CPU :  2  *   (Intel（R） Xeon（R）CPU    E5620 @ 2.40GHz  ) Core 4  , sum up 8 cores

2,RAM: 64 G

3, HDD: SAS * 4   ,disk speed 15000 ,  Raid 5 , IOPs 600 totally.

And i know 1 VM's start need 300 IOPs ,so when i start 40 VMs ,the start stormhappened.

So i want to know ,is there some way or solution to solve this problem.

Thank u guys very much!!!!

Hi,

I have recently added the Hyper-V role to my server running Windows Server 2012 and found that under power options I can no longer control the minimum and maximum processor states. The processor constantly runs at its maximum frequency

If I remove the Hyper-V role then the processor state options return.

Is this by design or a bug?

Is there a way to force the return of the processor state options? (it's the same across all 3 power plans)

Thanks!
