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.

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 installing a new server (Win Server 2016 Std.)  and considering installing a Hyper-V machine as a Remote Desktop Server to host Quickbooks Enterprise 2018.  
I've called Intuit support to see if they have installation and configuration suggestions or documentation and found them to be be (predictably) unhelpful.  They claim that they no longer support Remote Desktop deployments for QB Enterprise and suggest signing up for their hosted service (which sounds remarkably like Remote Desktop!).
I don't want to waste company time and money on server setup and CALs only to find that it doesn't work.
Any current users/admins out there with recent experience that can comment, advise, endorse or dissuade on this topic?
Any input is appreciated.

Hi everyone

I could really do with some help with a challenge I've set myself.

I am trying to create a new WIndows 10 "Gold" image with all our apps, settings etc.

I am trying to achieve this in Hyper-V on my laptop as I don't really have any other hardware availabe at the moment.

I am more or less familiar with the process of Sysprepping and capturing the image, but I have come across a problem that I can't figure out.

I want to install my apps etc from a shared folder on my laptop, however when I boot into Audit Mode to make the customizations, I cannot access the share.  I get the following error message:

<laptop> is not accessible.  You might not have permission to use this network resource.  Contact the administrator of this server to find out if you have access permissions.

This user can't sign in because this account is currently disabled.

If I log in normally, I can access the share.

I can't use an external USB stick or drive as Hyper-V doesn't seem to recognize them.

I also suspect I'm going to have this problem when I come to using DISM to capture the image.

To avoid me tearing anymore hair out, is it possible to build a Windows 10 image in Client Hyper-V.

I have a virtual machine running Server 2012. The host machine machine is running Hyper-V. I need the virtual machine to be on a separate VLAN with only internet access and possibly some limited access from other machines on the local network. The host machine connects to a Cisco 3560X managed switch. The switch is connected to a port on our Sonicwall firewall.

I am not sure what the best approach is nor would I know exactly how to configure it.

I think the main concern I have right now is how to configure the port on the Cisco switch. Will adding the VLAN during work hours cause any distrubtion?...Do I need to make any changes on the firewall?
I need to convert a physical Ubuntu server to a HyperV VM. What tool can I obtain to accomplish this task
Need to build a brand new from scratch 2 host failover cluster with Server 2016. Only a DC and F&P server are needed. There is no domain in existence currently. Therefore what would be the best order of steps to do this?
The VMs are on shared storage.

e.g. this did not work.
Build host 1 with Hyper-V
Add a VM as a DC and create new domain.
Add host 1 into the new domain.
Build host 2 with Hyper V
Add host 2 into the domain.
Add the Fail over clustering to each host and configure the cluster (including building the F&P VM) using the domain.

I have done the above as a test with the DC being added as a highly available server into the cluster.
Host 1 'owns' it. As soon as host one is forcefully switched off, the domain shuts down with the DC on host 1 and the cluster disappears from the Failover Cluster Management console of host 2.

Should i have 2 independent DCs (one per host) instead so that when one dies the other keeps the cluster alive?

Is there a best practice?

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?

I have a NetApp FAS 2520 running OnTAP 7 Mode and use it for my Hyper-V environment (storage for clustered Hyper-V hosts). I currently have a LUN mapped as a Cluster Shared Volume from the NetApp via iSCSI for my VHD and VM files. I have numerous separate LUNs mapped as volumes for my network shares (user files), SQL DBs and logs, SCCM repositories, etc. as I was guided by NetApp that this is the best way to set this up, likely because the initial thought was to use their backup and replication solution which we’re not using now.

I have recently switched my backup software to VEEAM. In using VEEAM, any of these VMs I’m backing up that have a LUN mapped to them for storage (file server, SQL server, etc.) need to use an add-on Windows Agent because of the non-virtual disk storage used.

So I’m wondering if there’s any negative impact in creating virtual disks in place of those mapped LUNs, moving the data to those, and then mapping those virtual disks as volumes so my VMs have all virtual storage and no longer need the VEEAM Windows Agent installed. Any thoughts on pros or cons of setting it up this way?

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

I'm using Hyper-v Sever 2016 wich contains several VM.
The need is to access a usb key from a VM.

How to do ?
Hi Everyone, just wanted to put this question out there.
I have a physical server running Server 2012 R2 with Hyper V.  Hyper V has 3 VMs, TS, Exchange 2016 and SQL 2008.
I want to do fail over cluster with a second box.
Can I just buy a second physical box, put 2012 R2 on it, install Hyper V on it and sync all the VMs over?

My searching online seems to say no, but there seems to be some that say you can.
I'm guessing I need a NAS or a SAN to put the Data on like Exchange store (DAG) and SQL Databases along with a dedicated IP network to run the replication data over, am I wrong?

Any input or ideas (clarification) would be appreciated!
Hi all,

please assist me with this. I have a scenario in which I have installed a Exchange 2016 server in a cleanly installed separate server 2016, and a separate DC running server 2016. I did this install about a month ago. these virtual servers are situated in my hosted environment on hyper-v.

I set myself up as a user after configuring everything and simply added my auto-discover addresses to my domain to point to the static ip of the exchange server and added all the relevant forwarders to my firewall at the hosted environment and everything worked fine.  I added my outlook email profile and setup my email account as normal, from remote (my office) over the internet to the remote exchange server, everything worked perfectly.

Yesterday, I had purchased a new motherboard and processor etc for myself installed a new PC for myself. installed my MS office, activated etc. and when it came time to add my email profile, I get the error, either that it cannot find the server or the credentials are invalid. I rechecked everything, I generated a self-signed certificate, installed it, checked all my auto-discover entries, checked the mapi virtual directory, even http://testexchangeconnectivity.com/ is completely green, as much as I could find, nothing works. the only thing that did work to successfully add the email account was to add RRAS services on the DC and dial VPN to the server from my Pc and then add the email account. Is there something I need to do specifically …
Any advice of If I should use antivirus at all on windows server 2012 terminal server that is part of a nested Hyper V. The parent Hyper V is a  windows server 2016 .  If so which Antivirus software?  (windows server 2012 not R2 64 bit)

Will have about 30 user pretty much using a proprietary real estate closing software for windows that software does have to contact a few websites. which is why I hate to have no antivirus but  I do understand I have the double whammy of a wanting windows antivirus with Real time scanning (why i cant use Clam AV)  in first a Virtual machine Hyper V and then a Hyper V terminal server with 30 users concurrently connected.
Dear Experts

I plan first to clone the VM from Hyper-v to ESXi 6.0 (via VMware converter - cold migration) to new HW and then I need to increase the VM's C-drive disk space. Best methods to do that?

We have four hyper-v nodes (Windows Server 2016) in the cluster, also we use ISCSI connection with storage.
This morning we got a situation that CSV goes on pause mode for some reason. In Failover Cluster Manager we got error 'STATUS_IO_TIMEOUT (c00000b5)' in failover cluster manager. SCOM monitoring system reports this error on nodes:

Windows Storport Miniport Driver has timed out a request
The monitor alerts when event 153 error occurs: Storport miniport driver times out a request.
Miniport driver may time the request individually instead of letting Storport perform the request timing.
If the requests need to be retried regularly, investigate the health of the disk subsystem concerning any performance issues.

We suspect that storage disk had a problem and send dump data. Somebody have an idea what can cause this issue?
Have one VM on Hyper-V that won't boot.  The VM's OS is Windows 10 pro, boots first to stop error 0xc000021a, then it continues to 0xc0000001, all other VM's are working just fine, but I can't get this one to start.  I have tried repairing BCD among other things from a Windows 10 iso.  Unfortunately it looks like the only backups I have are of the corrupted VM as well, so I'm thinking I'm screwed...

Any ideas?

After a hard struggle I have succeeded in converting a physical Server 2008R2 to a VM on my Server 2016.

My problem is, that I can not use the mouse in the remote desktop session.
I think this has something to do with the Integration Service, but if I check properties of the vm all Integration services is enabled.
Any suggestions? :-)
I have three Hyper-V servers that were being used for a project.
The project has been cancelled so apparently the servers are no longer needed.
Before I delete the servers, I want to "archive" them just in case I'm asked to restore them and use them again.
What is the best way to archive, store or export a Hyper-V VM to be used at a later date.
we are in the process of moving our physical servers to virtual . This is going to be the open tender based on our procurements process  . just I am wondering how can I give them the right information  . Please share your thoughts on the TEC evaluation point of view .

I am going to call for meeting to explain the requirements for  interested parties ? Or this there ant other way of doing that  ?

other thing is  we looking for one product due to the current OS what we have .( all are MS )
The Centos guest was a package designed for hyper-v, but apparently the Centos doesn't recognize the virtual network adapter.  There is no int0.  I've hunted around for solutions, and this seems fairly common for Centos and Hyper-V, and solutions have ranged from manually setting up the config files to installing Microsoft Integration Services (apparently MS doesn't have a package for this particular version of Centos), but I've had no luck with any of the solutions I've found.  Does anyone have any suggestions?
When log in to the server my profile is loaded. But for the second login either I am get blank or flickering screen.
When the first user logs off, the session is fine for the second user.
This is server is installed on VM.

What this can be? This is happening for 5 of my new applications servers. These servers have been built 3 months ago. I have not see problems before until now like 5 days ago.

Please advice
I have a Hyper-V Main  Win 2012 server that l have installed on a machine and then created a AD Domain with DHCP\DNS running on it. I then created 4 Hyper-v  Win servers 2012 VMs with static ip on it and connected them to the external network. When l try and join the servers to the domain it fails. I have made sure that the Vms servers have the main server as the dns. I have made sure the router is not issuing the IP addresses. However when l check my PC that l connect with to my network it shows the router as the DNS even though it gets its is IP address from the main server. I would greatly appreciate yours assistance.
