Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

I'm running Hyper V on my Win 10 Pro laptop & have a Win7 VM running there for learning my way around some POS software. I'd like to be able to use a CC swipe with it & see plenty of articles out there on adding a USB HD to a VM, but not so much something like a CC swipe.
The one I'm currently trying is an IDRA-335133B-DL. I found one article that recommended connecting to the VM via RDP, but it's still not showing up.
Any suggestions?

Hi, although I enable Intel virtualisation and update BIOS to newest possible version I cannot turn on hypervisor (or created virtual machines will not power-on because hypervisor not running).  

I seek some info on Google but they always referencing to Intel VT function on BIOS.

Thank you
For the past weej I have been racking my brain trying to fix this issue. We have a Hyper-V virtual machine Windows Server 2008 Standard machine that recently started requesting activation. When we try to reactivate we get :

Error Code 0x80070426 - Service Cant be Started.

I was able to identify the services by researching the error code as SLUI Service, and a service it is dependent on Software Licensing. It seems without these services running the server cannot authenticate the license. When we try to restart these services we get:

Error on restart - 0x80070005 - Access is Denied.
An unauthorized change was made to Winodws 0xc0020012

I have tried:
- Running Chkdsk - Fixed errors but no change to activation.
- Pushed into Last Known Configuration. No change.
- Attempted using cmd to start services - Received System Error 5 code
- Verified license is still good with Microsoft
- Attempted Integration Service Upgrade - Get Directory invalid error

So I am stuck an hoping someone has had this experience or a way to fix it.
I found a checkpoint of hyper-V guest without the option of Apply and Delete. It just got Export and Rename options. (see screen shot) Why is it?
Without Apply or Delete, how can I apply it?
We have two (2) Windows 10 Pro computers.  Both have Hyper-V VMs installed and in use (very low usage maybe 1 or 2 a week).  Both have their IP set manually in "Use the following IP address".  Finally, there is communication between the 2 computers in file sharing  and RDP.

The problem we are facing is that when Computer-1 Ping Computer-2, Computer-2 display a total different IP.   Yet when Computer-2 Ping Computer-1, it display the correct IP.

Please advice on how to identify cause and  how to fix.

Thank you in advance.
Our Windows Server 2012 R2 Hyper V server hosts a Windows Server 2012 R2 VM. An update brought an Integration Services Setup upgrade to version 6.3.9600.18692 (I haven't had time to locate which update this is). This upgrade doesn't appear to complete successfully in the VM, and a number of critical devices (including the NIC) have an exclamation sign on them. The Device status in the device properties says:
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"

After much research, I was able to implement a temporary fix by pressing F8 on the VM's boot, and selecting "Disable Driver Signature Enforcement". The VM then boots into the OS fine, and the devices do not have an error.

But this is just a temp (and potentially unsafe) fix. This appears to have occurred previously when Integration Services Setup upgraded to version 6.3.9600.18398, with MS releasing a "fix".

I would like to resolve it permanently. Any help would be greatly appreciated.
Is it now possible within the latest version of VMware to view and interact with a virtual operating system that is running on the actual VMware server's monitor (without having to use the VMware vSphere client running on a seperate computer)?
We have a Windows Server 2012 R2 Server running Hyper-V.  The virtual server is also Windows Server 2012 R2.  The virtual server is running SQL Server 2012.  I have allocated 16GB of RAM to the server and it has 12 virtual processors.  The resource manager shows that it is not being worked hard but we have a program that uses SQL to pull reports and it is extremely slow doing it.  Are there any thoughts?

Thanks for any help.
I am running Hy per v sever to my Domain controller, running SERVER 2012.

I can get on the internet from my server but going inside the VM and any client I can't connect to the server or the internet?
I enabled in hyper-v 2012 the use of dynamic memory for a centos vm
I followed these guidelines https://www.altaro.com/hyper-v/centos-linux-hyper-v/
I created a file in /etc/udev/rules.d/ named 100-balloon.rules
SUBSYSTEM=="memory", ACTION=="add", ATTR{state}="online"

Open in new window

I setup startup mem 1024, minimal memory 1024 and max 4096

unlike other centos vm's I have it starts consuming all memory
so, i gave it 8Gb .. all memory was consumed
I increased the max memory to 20Gb, and it was consumed

I have 2 Physical Servers - 1 Hosting 5 Vms and the other one hosting their Replica.
I am using the Windows Replication Services from Hyper-v

I would like to get a daily report by email that shows me if I have any problem with the replication.
I have found many PS scripts, but got lost, some are too basic, some are too complicated..
Is there anything "out-of-the-box" ? something Standard that any IT administrator should be looking at ?

Hello Experts!

I am having a weird issue with my SCVMM server. I have a Windows 2016 server with SCVMM 2016 installed on it. all patches to the latest version.   When I try to connect remotely from my desktop (Win 10), I can't connect using ' use current Microsoft windows session identity'.  What is weird, I specify the credential, and I put my credential and it works. I need to put  username instead of domain\username.

that being said, it cause backup issue as Veeam also connect using domain\username. I am pretty sure resolving one will also resolved my backup issue.

Any advice appreciated
I've got 3 virtual machines on an ESXi 5.0 host that I'm trying to migrate to a Hyper-V host using Microsoft's Virtual Machine Converter.  I kick off the conversion and everything goes well for a few hours until the conversion fails with the error code found in the log file I'm including.  I've tried this same process with two different VMs running on this same host and get the same error.

I found a KB (below) that seeming describes my issue.  This KB says that the ESXi server has to be managed by a vCenter Server.  That confuses me because I successfully completed a ESXi to Hyper-V conversion using the same  conversion software, but for a different ESXi host (running 5.1) for the same client yesterday.  This ESXi host was not managed by a vCenter Server.  There is no vCenter Server in this environment.

The KB article is below and the log file is attached.  Any help would be much appreciated!  Thanks!


We have been facing a issue in SQL connectivity between DMZ to Lan Network.

As Whenever we are trying to connect SQL DB server from Webserver (Located in DMZ) getting below error.
The Semaphore Timeout period has expired.

both server are on Hyper-V fail over cluster.
Recently rolled back our AD server (Windows Server 2008) due to a ransomware issue. After doing an instant recovery (Veeam backup & Replication) of the VM, the active directory is now corrupt. Is there a way to repair it?
In the process of setting up a DX100 S4 10Gbe iSCSI SAN and I am trying to work out how to present the storage to are Server 2016 Hyper-V Cluster (2x Servers) - the setup and configuration guides are not very clear!

I have managed to present the storage to one server, but the other server cannot see the storage! and the server which can see the storage I am unable to add into Failover Cluster Manager - no disks suitable for cluster disks were found.

I've setup many iSCSI SANs in the past (HP, Dell etc) with no issues
Hyper-V Guest OS 2012R2 reaches 10% and then fails startup  with Failed to change state - file not found. Only thing changed was Automatic Start Actions and Automatic Stop Actions.
now my top managements asking me to go with the design and build  concept that enable the parties to deliver the best solution base on the current setup  .and also they have advice me to do the high level documentation  to publish for open tender . now i looking for some kind of a support /sample  on the below

 Eg : Microsoft OR VM (both)
 Redundant hardware

Our current setup is:
-One single server (HP DL350G9) as dedicated hyperV host only for VDI (RD Virtualization Host) only
-Roles installed on physical box are: HyperV and Remote Desktop Connection Broker and RD Virtualization Host
-this hyperV host has 30 vm's with Windows10
-there is only one VDI collection
-inside virtual desktop collection setup \ Virtual Desktop Configuration \ Local storage is set for: Local and local virtual desktop creation location is set: D:\VDI

Q1: Is there a way to migrate current virtual desktop collection from physical host to vm ? without loosing existing 30 vm with windows 10?

Our goal is to move whole VDI setup as it is in to new cluster or other hyperv hosts.

We have a physical server HP server, running Windows Server Essentials 2012 R2. We ran the Disk2VHD tool to create the .vhdx image of the server.

When we try booting the VM of the 2012 server on a loan (Dell) server, we receive the attached error.

The VM is a Gen2 and we have tried turning secure boot off/on and changing it to UEFI bios rather than legacy on the VM to no avail.

Also recreated it as a Gen1 VM and we receive a flashing blank cursor.

I have a Storage Spaces in two-way mirrors. I understand it should be able to sustain at most one single disk failure. My question is, once I identify the failed hard drive, can I simply unplug the failed hard disk and plug in the good hard disk without shutting down the server as I usually do on a hardware RAID1?  If not, what procedures do I need to do? Thanks in advance.
Hi All

Does anyone know how to update to the latest powershell version on Hyper-V Server 2012??

I'm trying to find a simple, free or low cost solution to allow us to monitor the status of certain windows services, disk space remaining and Memory Remaining.

Is there a tried and tested agent that we can run on the virtual server to get this info?

After registering VM "in-place" at reinstalled Hyper-V server, the guest Windows Server 2012 R2 shows "no connections are available", even there is a network connection available, it does have IP address, it can connect to the internet...

Therefore none of the crucial services start up - I can only sign in via safe mode, as this is the domain controller...
Other VMs did register without any problem...

How to fix this network connection problem?
Good morning everyone,

I would just like some clarity on hyper V VM Licensing please.

Can i move VM guests to different servers with different Server2012 licenses?

If say one VM guest was built on a particular server, with Server 2012 License A, if i want to move it to another server with Server 2012 License B?

Once moved, do i update the VM guest with the License of the new physical host it now resides on?

Thanks all
