Hi there,

I have seen issues with integration services recently and am wondering what the correct method should be for installing integration services in an environment where you have VMM running. Let me explain..

I have a virtual host running 5 VMs. If I open up hyper-v manager and open a console and select "insert integration services disk" then the tools install fine job done. If I do this via VMM, (shut down the VM and select "Install virtual guest services") then the install says it completes succesfully. However, after installing the tools this way, I start to receive errors on my hyper-v host for those VMs similar to this below..

"Hyper-V Data Exchange connected to virtual machine 'servername', but the version does not match the version expected by Hyper-V (Virtual machine ID 9CA3A800-654B-495A-92BF-1639075E81BF). This is an unsupported configuration. This means that technical support will not be provided until this problem is resolved. To fix this problem, upgrade the integration services. To upgrade, connect to the virtual machine and select Insert Integration Services Setup Disk from the Action menu.

So to get around this error message I had to then go back into Hyper-V manager on the virtual host, open the VM via console and again choose "Insert intergration services disk" and reinstall that way. So basically it appears to me that installing the services via VMM gives you errors at the host level. Has anybody else experienced this? Should the integration tools be installed one way over the other? Should there be any difference between the two?

Problem

I am new to networking and trying to setup a lab environment using best practices so that the production environment can model from the lab.  As of now I can access (via ping)  any vm and the router from any other vm as well as accessing the host machines (via ping).  I can ping using IP addresses as well as using host names.  What I cannot do is access the internet from any of the vms or from the host machines.  I can access the internet from my laptop wich is behind the same router running Windows 7. 

Lab Configuration:

NetGear router 192.168.1.1

None of the machines in this lab are running a DNS.  I am currently using the ISP's DNS IP addresses.

Dell R300 with three NICs, we will call this one Server1

IPs: 192.168.1.101
      192.168.1.102
      102.168.1.103

subnet: 255.255.255.0

All three NICs are cabled to a single Dell switch.

On the host machine Windows 2008 R2 Standard edition is installed.  The only role installed is Hiper-V.

There are three virtual machines installed: 1 standard edition and 2 web editions. They each are configured with a single NIC and the IPs are: 192.168.1.104 - 192.168.1.106. No roles are currently installed on any of the gust machines. Using VMM the Local Area Connection 3 has been configured as a virtual network.  I have NOT enabled the VLAN-ID and I am not allowing the host machine to share the network.

Dell R300 with three NICs we will call this one Server2

IPs: 192.168.1.121
      192.168.1.122
      102.168.1.123

subnet: 255.255.255.0

All three NICs are cabled to the same switch as is used for Server1.

On the host machine Windows 2008 R2 Standard edition is installed.  The only role configured is Hiper-V.

There are three virtual machines installed: 1 standard edition and 2 web editions. They each are configured with a single NIC and the IPs are: 192.168.1.124 - 192.168.1.126. No roles are currently installed on the guest machines. Using VMM the Local Area Connection 3 has been configured as a virtual network.  I have NOT enabled the VLAN-ID and I am not allowing the host machine to share the network.

Goals

My end goal is to have AD/DC installed on the two vms running standard edition and two vms each with an External DNS on web edition and a SQLServer instance installed on one vm and Web Server installed on another vm.

My immediate goal is to access the internet to update the machines and I cannot.  Any help would be greatly appreciated.

Thanks.

All VM are Win2008R2 and Win2003

When I try and migrate any vm from node 1 or 3, I receive the following in the Cluster Event Viewer:

None of the error details point to what may be causing the migration failure.

Can someone explain how I should approach troubleshooting this?

Thanks.

One sees many posts against using snapshots on virtualized domain controllers. If the VM is running at the time the snapshot is taken, this makes a good amount of sense. But if the VM is off, how is this fundamentally different than any other means of backup???

In a larger sense, if ALL of the machines in a domain are cleanly shutdown, then snapshots taken, are there really any issues if the entire domain is restored back to the snapshots, even is significant (but less than tombstone) time/operations had occured in the mean time???

Why does deleting a VM from Hyper V manager take a very long time? It just  removes metadata , correct?  Hyper V shows Operation "Destroying 3%"  and it seems like this takes forever to complete

I'm having some trouble with my new server so I decided to export my 2 VMs, re-install 2008 R2 and then import my VMs.  One VM worked fine but the other, which is the DC, had problems.  It had no network access and if I tried to open network settings the screen would hang.  The rest of the server was fine but I could not get into network settings.  Ipconfig showed no addresses for the server.  I tried deleting and recreating the virtual NICs but no matter what configuration I tried I got the same result.  I read somewhere that when moving VMs you should recreate the virtual networks before importing which I tried to do but maybe didn't get it right.  At any rate it didn't work so I restored the backup.  Any help would be appreciated.

We are installing Snort on Linux inside of VM. Outside of the box we are sending traffic to a one of the nics on the server. That nic is mapped to that Linux server. We are not seeing all of the traffic inside the VM. This is because of the virtual switching inside of Hyper-V, right? Is there anyway to do this or Hyper-V flat out not going to work for something like this? Thanks.

Hello Guys,

I know this may seem simple to an expert but the online information to me is ambigous like the term "lightly virtualized", whetever the hell that means. So here is my question, I have an HP system with 10 blades and each blade is really a server with 6-8 cores. Each blade will hold about 5-8 virtual servers. First, do I need 10 licenses of Windows Server 2008 Enterprise, meaning one for each blade?

And what is the least expensive way I can virtualize with Hyper-V? I don't need DRS and advanced features but I do want SCVMM 2012. Can the HP system mentioned above work with the Standard or do I need the Datacenter version?

We are moving away from VMware because the licensing is too expensive for Academic environments.

Thanks,

RT

Hi,

I'm using Pass-through Disk on Hyper-v Server 2008 R2 and I note very bad disk performance.
I'm using a Dell Host, Q-logic FC Adapter, and HP MSA SAN.

On the same Host, I compared 2 situations:

First, a VM (2008 R2) with pass-through disk connected on SCSI controller, HD tune measure 89,8 MB/s !! Very bad.

Secondly, the same VM on the same host I attached a Virtual Hard disk located on the SAN. HD tune measure 1773 MB/s!!

It seems that pass-through mode degrade disk performance.

I think problem doesn't come from SAN because I get very good results with Virtual Hard Disk on the same VM.

Is anyone have an idea ??

Thanks a lot

Is Hyper-V Replica SAN Aware such that the replication traffic can be done at the SAN level (between 2 SAN devices) instead of at the server level?  This would reduce the burden of compression CPU cycles on the servers as well as remove the 5 minute interval issue that Hyper-V replica has?

Which SAN's support this feature?

Hi

We have two HyperV servers in two blades each having one VM in it. We need to map one LUN from IBM DS 3512 Storage to both the VMs. That lun will be used as Clustered Disk in both the VMs as we need to configure a cluster between the two VMs. We cannot use ISCSI as the feature is currently not available in IBM 3512 Storage. Any suggestions would be appreciated.

Thanks in advance.

I have found that pass through simply does not work, and it's not clear why.  All articles say you simply set up the partitions on the disk on the host, take the disk offline, add it as a SCSI disk to the guest, and there you go.  However, this does not give the guest access to the disk in any way as it does not show up in Disk Management in the guest.  I briefly thought that due to the VHD size limit, perhaps there is the same physical limit and Hyper-v can only use MBR volumes, but it seems that should not be the case according to other threads.  I'm at a loss as to why all articles make it sound like this should be simple, and yet it simply does not work.  Any advice on how to make a passed disk actually show up in the guest once it's been added to the settings would be appreciated as there is apparently something missing from all these instructions.

I hate to have to create a trio of VHD files on the external esata RAID and mount those in the guest, especially since creating fixed disks of that size takes hours, but without being able to actually give the whole drive to the guest it seems I have no choice.  If no one has any ideas I'll have to chalk this up along side the inability to virtualize USB devices making Hyper-v a rather limited solution.

I'm also wondering why posting to existing threads in this forum doesn't work.  I had to make a new thread instead of tack on to past relevant ones.

Hi

I am noticing performance issues on my Hyper-V virtual servers, especially with my terminal servers, Exchange box and SQL.

Setup on the 2 Physical servers themselves are Windows 2008R2 Enterprise, over 60GIG RAM on each node, both nodes are in a cluster, storage is on a iSCSI SAN and the Hyper-V traffic is run through two of the four ports on a NC375T HP NIC teamed with HP Teaming.  The VM's have fixed HDD's, I can't see any issues with performance around CPU or RAM usage.

I have been reading alot about disabling IP4 Checksum Offload or offloading etc on the NIC's, not sure on the phyiscal NIC themselves, the Microsoft Virtual Machine Bus Network Adapter on the VM's or under the Teamed Settings on the physical hosts...

Any idea's or hints would be great.

Thanks
Mark

Good morning,

we have a Hyper-V Server 2008 R2 with all updates.
A tandberg RDX USB-drive is connected.
The RDX is formatted with NTFS and use Bitlocker drive encryption.

We change the taps daily. After the change it isn't possible to access.
In the device manager the tap hasn't a file format.
Then I restart the Hyper-V Server 2008 R2 and the access is possible again.

Also I installed the official Microsoft hotfix:

I've installed Hyper-V Server 2012 RC (Core) on one machine and Windows 8 Release Preview & RSAT on a second machine.

Following these instructions I was able to install the BitLocker feature on the Hyper-V 2012 machine.

http://blogs.msdn.com/b/virtual_pc_guy/archive/2010/11/11/configuring-remote-management-of-hyper-v-server-in-a-workgroup.aspx

But when I try and enable the TPM as I've done in the past (this command worked with Hyper-V Server 2008 R2) I get the following error message.

manage-bde –tpm –TurnOn

BitLocker Drive Encryption: Configuration Tool version 6.2.8400
Copyright (C) 2012 Microsoft Corporation. All rights reserved.

ERROR: Manage-bde cannot manage the Trusted Platform Module (TPM) in this
version of Windows. To manage the Trusted Platform Module (TPM), use either
the TPM Management MMC snap-in or the TPM Management PowerShell cmdlets.

Given I am running Hyper-V Server core I cannot run tpm.msc (which I believe is the aforementioned "TPM Managment MMC snap-in"?).

I tried searching for "TPM Management PowerShell cmdlets" (and related search terms), but haven't run across anything that explains how to enable BitLocker on Hyper-V Server 2012 RC via Powershell. I was successfully able to install Hyper-V Server 2008 R2 and enable BitLocker on this same hardware.  Any help would be greatly appreciated to get BitLocker working on Hyper-V Server 2012 RC.

Hi,

I am Volume License User.

I installed and activated Windows 2008 R2 SP1 Datacenter Core ed. with Hyper-V role on it using ISO and MAK key provided by the Volume License service (I have less then 5 physical 2k8 systems so KMS would not work).

I installed number of VMs (using same ISO as for Host) based on Windows 2008 Standard in Core and Full editions and I am trying to activate them but none will accept the MAK key used for the host Datacenter edition which should be the way to proceed if I understand correctly.

when I run command

slmgr.vbs -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (MAK for our Datacener)

I am receiving error:

"On a computer running Microsoft Windows non-core edition, run 'slui.exe 0x2a 0xC004F015' to display the error text. Error 0xC004F015"

Which translates to: The Software Licensing Service reported that the license is not installed.

Without being able to register the key I cannot proceed to activation step.

What am I missing? Or how it should be done to avail of unlimited VM activations on Windows 2k8 Datacenter ed.?

Thank you,

Sebastian Korfanty

Hi,

What are the consequences of not exporting and importing VM but instead creating new VM and attaching VHDs from previously existing VM with already installed and working DC or any other role (besides loosing the network configuration of Guest OS).
