Dear Hyper V Expert,
I am currently having a hyper v server running windows server 2012 standard. i have vm that being installed with windows server 2008 R2 Enterprise. suddenly, the VM is crash and from the hyper v console i am only able to view as 16 colors. I found that the hal.inf file is missing inside the windows-system32-inf folder. is there any way to regenerate the file?
Thanks.
Regards,
Dear sir
We have configured hyper v as a role in windows server 2012 datacentre.Then in hyper v manager we create a external virtual switch and configured two vps server one in windows server 2008 and other one in centos.when vps created we fill in the ip and dns server details inside the vps machine on the same subnet that of the virtual switch of base machine.
But inside vps it gives error unable to connect to dns server.
can you please help us on this
Thanks
Hi,
I've had a Hyper-V running Windows Server 2008 for about two years. Today I did a Save on the VM in the Hyper-V Manager and then restarted my computer. When computer restarted I went to Start this VM and got the following error:
[Window Title]
Virtual Machine Connection
[Main Instruction]
The application encountered an error while attempting to change the state of 'WindowsServer2008'.
[Content]
'WindowsServer2008' failed to restore.

===============
The Event Viewer had no additional error information and just repeated the above messages. I did not change any monitor or drivers on my system. I started up a different VM on my system that runs Win 8.1 and that came up with no problem.
What can I try to fix this?

Hey guys,
How can I get Hypervisor to force to stop a virtual machine that is in critical stopping mode?
I have restarted the Hypervisor server but it doesn't let me do anything to the virtual machine that is in critical stopping.
Thanks.
I have created external virtual switch and same is used VM (windows 2012 DC server) now I need to assign IP address statically after assigning IP static (same range of physical machine with subnet, gateway,DNS but still internet is not working on VM (windows 2012 DC server) what network settings needs to change to make internet work with static IP. Screen shoot is much appreciated
Hi,
I have a problem with Hyper-v and MS SQL.
The problem is that the queries are slow. I’ve made a test script that makes 100.000 dummy rows, the results are as following:
VM 1:
Host: Xeon 2620 v2, 48GB memory, 512GB SSD iSCSI (2 nodes CSV cluster, all nodes and data server same specs).
VM: 2vCores and 6vCores, 6GB memory.
Test takes 2.40 minutes.
SQL 2014 Std.
VM2:
Host: Xeon 2620 v3, 64GB memory, 512GB SSD RAID1.
VM: 6vCores, 20GB memory.
Test takes: 44-59 seconds.
SQL 2012 Enterprise and Std.
VM3:
Host: i5 4660, 8GB memory, 256GB SSD non RAID.
VM: 4vCores, 4GB memory.
Test takes: 42-58 seconds.
SQL 2012 Std.
VM4 (VMware):
Host: i5 4660, 16GB memory, 128GB SSD non RAID.
VM: 3 vCores, 4GB memory.
Test takes: 17 seconds.
SQL 2012 Std.
I’ve also tested with RAM Disk, those test are of course faster (Hyper-v and VMware). Beside that, one database is 22GB big..
One this that I noticed. In Task manager, when the test script runs I see the write speed of the disk going up to 2 mb/s, it won’t go higher.
Any suggestions to make it go faster?

I have a physical host running windows 2008 with hyper v installed and a VM running on top of it
When I try to connect to VM from hyper v manager , it says "authorization failed"
error message: "This user account cannot access the virtual machine's video"
I am logged in as a user with admin privileges to the physical host
thanks
Is it possible to upgrade Hyperv Free to Standard. I have a couple servers running the free version and found that I do not have the ability to run performance reports on it. I have purchased Windows 2012r2 Standard Licenses for the host. Hoping there is an easier way than wiping the machine.
Thanks,
The Techguy
In our Hyper V 2012 (non R2 !) environment, the hosts are reporting errors like the below....
'9E0348EA-1374-481B-A3C1-1F2672DE1DD3' failed to create scheduled task based on information stored in the respository: Unspecified error (0x80004005). (Virtual machine ID 9E0348EA-1374-481B-A3C1-1F2672DE1DD3)
------ There is no real VM with this UUID.. Maybe a deleted one..
Question I have is :
Should I worry about the above?
If not, how can I stop the error being created in Hyper -v vmms log?

Hi
My client has a server running Server 2012 with Hyper-V. The Hyper-V image is Server 2008. I changed the basic disk type in the Hyper-V to dynamic and need to change it back to basic. What tools can I use? Will this cause data loss or any type of application/software issues? Is it safe? Will I need to rebuild the Hyper-V server?
It was converted to dynamic in order to create a partition to do a system state backup and then copy the system state to another machine on the network.
A second query I have is to find out if there is a way to do a system state backup to another device or drive. When I tried to do a system state backup in the Hyper-V server it would not send it to any location on the network. I mapped drives and shared them however it would not work. The CMD prompt told me it was not possible to send a system state across a network or USB drive. Any ideas? Where am I going wrong? I am using the wbadmin command for the system state backup.
Regards
Sean
Hi
Sorry for the very long title.
I currently have testing environment on 2 Windows 2012 servers, both have Hyper-V, Failover Clustering, and the Cluster itself set-up. I have iSCSI storage, that is setup on a third server with Windows iScsi Target Software, this is the cluster storage.
On Server 1, which hyper-v is installed I have a VM, Gen2 VHDX differencing disk, with 2012 parent disk. This has no problems booting up and runs fine.
I have setup a General File Server Role within the Failover Cluster Manager, and on that created a SMB Application share.
On that share I can move the parent disk for the previously mentioned VM.
When I try to then live migrate or failover that File Server onto another cluster node, the VM crashes.
Is it possible actually have a highly available store for parent disks? If so, how would I go about implementing it?
Thanks
A couple of times I've noticed odd things happen on the Host caused by a VM even if the vNICs are not shared with the Host OS.
For example: If a VM is running Windows 7 and the Windows Easy Transfer Wizard is used, a drive letter is automaticallymapped on the Host as a removable drive pointing to the vhdx hard disk of the VM.
How is that possible?
I run Windows Server 2012 RTM Hyper-V and I can occasionally not access the second virtual hard drive (dynamically expanding VHDX) attached to the VM through the virtual SCSI controller. I can however access the first hard drive that is connected with the virtual IDE controller.
I get the following warning in the event log under “Administrative Events” every 30 seconds when this happens:
I get this error once or twice a week and it has caused serious problems since one of the virtual servers that have this problem is a fileserver and the second hard drive contains all the data.
The only quick solution to the problem that I have found is to force the virtual machine to stop using the “Turn Off” feature since a normal shut down does not work (stops at shutting down the event log or similar) and then start the virtual machine again.
You can also wait for about 30 minutes or longer until the disk for some reason becomes accessible again by itself.
My research into this problem shows that:
I have now attached the second virtual hard drive to the virtual IDE controller to see if this permanently fixes this problem (i.e. does not happen for at least a week).
Is there something wrong with the virtual SCSI controller or the virtual SCSI device driver that comes with Windows Server 2012 RTM? Does anyone else have this problem?
Hi!
I'v got some errors during replication of virtual machine.
Please help me to find out the reason of these errors.
'': account does not have permission required to open attachment '\\SVM01\ASR_VMs\d50ee8ba-f0e4-4169-b665-0e9bbfc831ad-8\MY-DISK.VHDX'. Error: 'General access denied error' (0x80070005). (Virtual machine ID )
'VM' failed to perform the operation. The virtual machine is not in a valid state to perform the operation. (Virtual machine ID 14F20527-C895-44B2-90B0-A1021C311251)
All replica VMs are stored on SMB File Share (CIFS NetApp 8040).
On both sides i'm using Windows 2012.
