Hello All.

We have recently upgraded from server 2008 to 2012 R2 but are unable to run or create any virtual machines. when creating a virtual machine we receve the following error.

The server encountered an error trying to create the virtual hard disk. A virtual disk support provider for the specified file was not found.

All that I have been able to find on the issue so far is for server 2008 which we did not have any issue with.

On going to device manager their is no virtual hard disk loopback driver. If I apply the registry fix for server 2008 (https://support.microsoft.com/en-nz/kb/2013544) the device loads on reboot but as a hidden device that is not plugged in. When trying to create a virtual machine again the driver try's to load but comes back with error 38 the device cannot load because their is one already in memory. After rebooting it is again not plugged in.

only other things installed on the server is the HP drivers and Backup Exec 2014.

So, I've got a Centos 6.6 VM running in Hyper-V, and right now I can 't even ping the host.

Currently I have set NAT between my external (which has both 10.1.11.1 and x.x.x.x) and internal (which has 10.1.11.2). I set my gateway to 10.1.11.1. Any idea what I'm doing wrong, and what I should change? Bridging is not currently an option, I only have one public IP for the host.

Thanks in advance!

Hi all;

Are there any ways to speed up VM connection from Hyper-V Manager console or Failover Cluster Manager console?

Thanks

Hi everyone,

I deployed 2 hyper v vitual machines a while ago, and i did that because I needed to test my current game Project, which is an

online game. However, i've had some problems with my Windows installation then I had to reset the pc by making it a refresh

install. I still have the hyper v virtual disks, but i cannot attach it to a new hyper-v virtual machine. it pops up this message:

"the storage

where the virtual hard disk is located does not support virtual disk sharing". I dont know anything about virtual machines, so I

didnt know I had to make the disk sharable. How can I force to attach the hard disk to a new hyper-v? I dont want to go t

hrough the whole proccess of installing the operating system all over again and updating it....

Any help is greatly appreciated!

Thanks in advance,

I have a dual port 10GbE nic in each of my two Hyper-V 2012 hosts (2012 R2). What would the PowerShell look like for this setup:

Hi All,

I have VM Named as "ERP" Operating System LINUX Machine Placed at Primary Data Center.DR Site Connected with 4 Mbps link

Now this VM Creates Backup Daily on VM Hard disk it self.

We have enable replication on this machine excluding of that drive where backup creates.

but still replication health is in criticial state and replication cycles completely very slowly.

i have a question there are only few GB's chance in this VM machine excluding backup activity which is approx 50 GB.

how can be long pending data so high if changes drive exclude.

I have a problem where one of my 2008 R2 virtual servers are shutting down unexpected every Friday at more or less the same time. This has happen 2 Fridays in a row now and the time is 13:01:30 and 13:01:10. I did some investigation on the event viewer and it tells me the following: (Error) The previous system shutdown at 01:01:10 PM on ‎2014/‎08/‎01 was unexpected.  Event ID: 6008 which I have goggled and did not find much on this ID?    I also found the following event more or less the same time as the first one: (Critical) The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Event ID: 41.  In most posts it looks like if it could be hardware related? But how do I justify this on a virtual machine?

Some Infrastructure background: It is a 2008 R2 virtual server running on 2012 Hyper-V, 2012 server. SCVMM is not configured so all administration is done through Hyper-V manager. The virtual machine is backup up by Symantec backup exec and the Full backup only start at 23:00pm night time. No scheduled shut-downs are configured and all servers are running on UPS power, the virtual server are also configured to boot up automatically after any failure. But in this case the server is completely shut-down and I have to manually start the server up again.

I hope there are somebody who can give some guidance on my problem?

I have two virtual machines both are hosted on same HyperV. 

I need to debug kernel of VM1(windows server 2012r2) from the VM2(windows server 2012r2). I know how to prepare the client machine(VM1) using "bcdedit " and also created required pipe setting. And I also know I could perform the debugging from the host using "windbg" by connecting to the named pipe. But I want to know how to debug this target machine(VM1) from another VM(VM2 hosted on the same HyperV where VM1 is hosted.

I tried to debug the VM1 from VM2 the same way as is done from the Host; but I failed to debug....

Dear All,

        We have 4 Hyper V VM installations on 2 HP DL 380 G8 servers and have they are connected to HP NSA 2040 SAN Storage through 6 Gbps Fibre channel. The physical machines are clustered.

Out of the 4, 2 are Clustered Hyper V's running Microsoft Dynamics AX 2012 R3 and we have 2 Clustered Hyper V for Database server running MS SQL 2012 R2.

The issue here is that the APP servers are slow in communicating with the DB server. The Hyper V's have a dedicated 4 * 1Gbps interface cards teamed and the packets are getting timed out. But from any other machine in the subnet the communications are proper.

When ever i try to copy a file from the DB server to the APP server using SMB share it kills my network, the copy will happen but after the copy is completed the network comes backup.

Its strange scenario. APP server 2 APP server smb copy is fine, and from DB to DB smb copy is fine but cannot copy between them.

Can anyone please help?

Thanks,
Sriram A Das

Hi,

Could you please advise if we need hyper-v license for new single server that will be used for development environment only (about 10 VMs)? Does it meters if we use for dev or production environment?

Another question, if we can "Microsoft Hyper-V Server 2012 R2 (x64)" from MSDN subscription, does that mean we have license and can install Hyper-v?

Thanks

With first generation all works fine and I was able to boot Ubuntu from differencing disk, but with second generation I got: Bool Failed. EFI SCSI Device.

Ubuntu is installed with UEFI (checked with this simple tests) boot and loads normally.

Secure boot in Frimware is turned off

Thank you

Can HyperV and SOFS co-exist on the same cluster node?  NO Hyper-V will not be used to access the SOFS shares but instead have their own disks not part of SOFS.   SOFS will be accessed by other server outside of the cluster.

Up to this point I have only read that Hyper-V can not be used to access SOFS on the same cluster using loopback.  But in the proposed configuration, loopback is not part of the solution.

Gurus,

I have tried installing a virtual Windows 2003 on a Hyper-V virtual machine and the installation goes through the reboot phase where 2003 starts up and continues with the setup, without any issues till it gets to the Regional and Language Options page. Clicking Next, Customize or Details buttons only causes the Regional window to act as if another dialog box is still open in modal mode somewhere.

I have tried the same on two other 2008 R2 host servers with the same result.

To help understand the failure's look, I took a 22 second video of the screen while I was clicking on the Next, Customize, and Details buttons but the result is the same regardless where I click on the screen. You will notice the Windows 2003 Regional screen's title bar flashing momentarily after each click. I clicked three times on the Next button and once each on the Customize and Details buttons.

The video files that I uploaded are each with different codecs, so please pick the one that best suits your installation.

I have a server that has three physical adapters. Where it sits now there is only one link so only one NIC is on the physical network.

My question is with Server 2012 R2 Hyper-V. Can I create an internal switch and route it out the physical network adapter, or create an external switch on an unused network adapter and route it out the connected one?

I'm trying to migrate a bunch of guest VMs from 2012 servers to 2012R2.  I'm running Compare-VM to get a Compatibility Report.  The issue that I'm having is that no matter what incompatibilities I have, there only exist one incompatibility.  This is message ID 21024 'Virtual machine migration operation for 'guestVM' failed at migration source 'srcServer'.

I can see on the destination server that there are events in the log for the actual incompatibilities, be they processor incompatibility, incorrect network name, etc.

How can I convince Compare-VM to return the actual incompatibilities?

Thanks

Howdy,

I'm just wondering if there's a Powershell command or somewhere in the VM properties that might show me which ID created a given VM and when it was created.  Anyone know if that's something easy to find?

If it's a script I can run against a bunch of VMs at once, that'd be great.  Or if I have to check the manually, that work too but wouldn't be as ideal.

Thanks!
