I have copied an existing virtual machine hard disk files from V drive to C drive by shutting down the VM.
When I tried to create a new VM with those hard disk file, I am not able to attach those files. what could be the reason ?
Thanks,

Exchange VM lost network connectivity from different subnet
Hi all,
Few times i have faced anniong issue. All times it was issue with Exchange 2010 VM's (Different Exchange servers from different domains). HyperV 2008 R2 and 2012 R2.
Server lost network connectivity from all other subnets. But in local subnet everithing is Ok. Most of communications is in local subnet but send/receive connectors stops working. After VM reboot everything becomes fine.
MAybe this is not HyperV issue but I saw those problems only vith virtualized Exchanges.
Maybe someone have seen similar issues and can provide solution.

VM Generating High Network Traffic
We Have IBM Blade Placed on Cloud Location and Connectivity Between our office and Cloud location is through dedicated 6 Mbps network (Layer-2)
On IBM Blade Windows 2012 Server with Hyper-V. We have 3 Hyper V Host, Windows 2012 Server with Hyper-V, on which we have created different VMs.We have created a VM and installed Oracle Unbreakable Linux 6.5 as a guest machine.
In this guest machine we are running our Oracle EBS server (Database 11.2.0.2.0 and Application 12.1.3)
When We Enabled Workflow Notification Mailer (It’s For Sending & Recv) our network packets are breaking. We have informed to our local ISP they told us that your database machine sending massive data that’s why the packets are breaking from HO to ALL VM inside Hyper V.
Can Some one guide us and share your experience to resolve this issue.

Network adapter Configuration error in Hyper-V 2012
We have a Server 2012 Failover Cluster with 4 nodes in the cluster. We just migrated from Server 2008 R2 SP1 using the cluster migration wizard last week.
When a VM is in a "Stopped" state and I do a "Quick Migration" to another node in the cluster, the network adapter loses its connection to the virtual switch and I get a "Configuration Error".
When a VM is powered on, live migration and quick migration work fine.
This was never a problem before in Server 2008 R2 SP1 and there was a refresh vm configuration option which resolved some of these issues but that doesn't exist in 2012.
Is this a bug or is there something I am missing?

Storage Pool Issues
Hello!!
I have some LUNs that was automatically added to a Primordial Storage Pool. I can't remove those disks and not even remove the LUNs.
I need those LUNs to use as pass-through disks to some highly available Virtual Machines. I need this scenario because I need performance. I'll virtualize a database server.
Using Set-PhysicalDisk i got this error:
[code]PS C:\Windows\system32> Set-PhysicalDisk -FriendlyName 'PhysicalDisk18' -Usage Retired
Set-PhysicalDisk : Not Supported
No linha:1 caractere:1
+ Set-PhysicalDisk -FriendlyName 'PhysicalDisk18' -Usage Retired
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (StorageWMI:ROOT/Microsoft/..._StorageCmdlets) [Set-PhysicalDisk], CimException
+ FullyQualifiedErrorId : StorageWMI 1,Set-PhysicalDisk[/code]
I'm kinda desperate, my schedule is tight 'cause I lost some days fighting with an Informix bug. I lost 2 VMs because I needed to add 2 more LUNs to the cluster and a lot of disks was suddenly added to the Storage Pool, dening acces to those disks.

An error ocurred while attempting to change the state of virtual machine XXX.
Hi guys,
I'm getting this errors trying to start some VMs. If the parent is restarted, they work again.
I have found no particular reason: a working VM after a Windows restart (in the child partition) stop working, stuck at "Starting 50%" and gives this error.
Ideas?
Thanks a lot!

Hyper-V KVP and SCVMM Guest Agent?
We are running RHEL 6.5 and CentOS 6.5 as Hyper-V guests under Hyper-V 2012 R2 with System Center Virtual Machine Manager 2012 R2 U2. If we have the SCVMM agent 1.0.2.1014 installed, should we also install the Red Hat supplied Hyper-V Key Value Pair
(KVP) package (hypervkvpd.x86_64) via yum?
I've noticed that if neither the SCVMM guest services are installed nor the Hyper-V KVP, VMM reports that no guest services are installed. If just the Hyper-V KVP daemon is installed, guest services are reported as 3.1. If both the KVP daemon and the SCVMM agent are installed, guest services are shown as simply detected.

Virtual adapters naming
Hello!
According to http://technet.microsoft.com/en-us/library/hh848564.aspx a new virtual adapter being added to a VM gets the name “Network Adapter” by default, but we can specify any other by using the "-Name" parameter, for example:
Add-VMNetworkAdapter -VMName Guest1 -Name "Nic2"-SwitchName VM1
Q: Why in this case the specified name is not used in the Device Manager inside a VM?
Thank you in advance,

32bit graphics mode for Guest virtual machine
Hi,
Working in a project I got a question that I was unable to answer myself, so I turn to the experts :)
We have an environment running with Hyper-V 2012R2 and guest that run Windows 2008R2.
Google earth has to run inside the Guest vm to be accessed via Citrix XenApp.
Google Earth requests a 32bit graphics mode to be installed.
So far no harm done.
What we noted was that we only could select 16bits graphic modes in the guest vm, running Windows 2008 R2.
The question is simple yet I can't find the answer, is it possible to have 32bit graphic mode options in a guest vm running 2008R2 with Hyper-V 2012R2?
hope you can shed a light on this
I've included the screenhot so you see it only shows 16bit modes.
Thanks for the help
Greetings

2012 R2 Generation 2 VM Boot Failure after Migration
I have encountered an issue after migrating virtual machines to a new host. It happens whether the VM has been moved with live migration or though a shutdown, export, import process.
The hosts are both 2012 R2 Datacenter. The virtual machines are Generation 2 and also have 2012 R2 Datacenter. All the systems where installed with the April ISO. The only difference between the hosts is that one only has no other updates. The other has
all recommended and optional updates as off 2014-10-10.
Once the machine has migrated to the updated host the next time it attempts to boot up (after a restart, ect.) it will fail with one of these two messages.
This happens whether the virtual machine has updates or is a fresh install from the April ISO. Once the machine is migrated back to the host that does not have any updates it will boot back up without any issues.
Notes:
The virtual machines where created on the host without any updates.
When creating a new virtual machine on the host with updates the 2012 R2 ISO bluescreens.
I setup another host machine without updates, tested migration to it and then ran updates. Same issue occurs.
I have tried boot with and without secure boot enabled also tries it with drive signature enforcement disabled. No change either.
This does not happen with generation 1 machines.
What I am trying to figure out is, if it truly is an update issue which update might it be so that it can be avoided? It would also be interesting to figure out if there is a workaround to get affect virtual machines to boot back up.
Let me know what your ideas are or if there are any other tests you would like me to provide.

Hyper-V Replication over Dedicated LAN and "is alive" checks over Corporate LAN
I am testing Hyper-V replication to see if it will be a suitable replacement for the ArcServer RHA product. One thing I am struggling with is configuring the replication to use the dedicated LAN, but still have the host servers verify over the corporate LAN.
I have seen the blogs on how to use a dedicated route and editing the hosts file to get replication to use the dedicated LAN, but that also changes the LAN in which the host servers communicate. It seems to me that if the corporate LAN were to go down on the master server, I wouldn't be able to fail over the virtual machines to the replica server without first having to connect into the master server through the dedicated LAN of the replica server to shut down the virtual machines.
I need to be able to fail over to the replica server if the corporate network connection on the master server drops without having to go through the extra steps of connecting into the master server first.
Is it possible for the two items to be separated? Can I tell Hyper-V to replicate using one specific IP destination on the dedicated LAN and have the replica server check to see if the master is live over the corporate LAN?

Windows 8.1 Prof and Hyper-v Server 2012 R2 core export snapshot hile VM is running
Hi,
I have ugraed my client to Windws 8.1 prof. After some digging i found out that it was posible to export a snapshot(if you have multiple snapshot) while using Hyper-v manager in windows 8.1 to a Hyper-v 2012R2 server. In my old pc win 7 prof i had the option
to export but it didt work on running VM. On the win 8.1 i dont have that options? am i missing some updates?
Any tips? fix?

Hyper-V causing intermittent network issues on Host?
I have a strange issue, I am not entirely sure Hyper-V is causing it, but it certainly seems that way.
Scenario
Host: Windows 8.1
Network Adapter: Intel Dual Band AC-7260 (Wifi)
Network Adapters (relevant ones are highlighted yellow)
Issue
When I continuously ping my wifi router (on the host machine), it intermittently drops. See the screen shot below.
This issue also manifests itself within the Virtual Machines as the machine constantly getting a DHCP IP address and then losing it. This happens continuously every few minutes.
Currently, I can resolve the issues by disabling Wifi on the host and then re-enabling it. I sometimes have to do that 2/3 times for it to stop dropping out. But it does fix the issue.
What have I tried?
I have been in contact with Dell (laptop is an XPS 15 2013) and Intel support. They have replaced the motherboard and now they want to replace the WiFi card. Personally I don't think it will help.
Why do I think it is HyperV related?
If I run the host machine with the VMs powered down, I do not get any issues. However, as soon as I start any Hyper-V VMs, the issue will usually start pretty quickly.
What it isn't.
This is not related to wifi signal or anything like that.
- The wifi router is 2 meters from my laptop.
- Other devices in the house do not exhibit this behaviour
- The behaviour is consistent across all networks (office, home, coffee shop etc)
Thanks for any help.
