Hyper-V

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?

I have created a VM let say VM_A in Hyper-V  (and install win 2012 ) and i would like to create more VM.

I used the sysprep to the virtual hard disk which i have already created.
Then for the other VMs i need to  create the VM with out the installation of windows 2012 , copy the Virtual hard disk of VM_A to the other VM let say VM_B and rename the VM_A to VM_B.

After this then i will start the VM_B and everything will be ok or i need to do something else?

Hi experts,

Can someone please give me a precise formula for calculating how many cpus are available to be allocated to vms and what the current ratio is?

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.

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)?

I have a physical HDD of 1 tb, I add (somehow) a VHD of 2tb, (sorry newbie here), now I remember somewhere saying that I could do that (add a HDD bigger than the actual size of the physical).
Now my VHD apparently has reached the point to max out the 1 TB, and of course I cheated the VHD to 2 tb, so my problem is now that I had to add another HDD and somehow let Hyper V that it can use this other physical to compensate for the missing space and I have no idea what to do...
So to recap since I know is confusing:
1 physical HDD of 1 TB, I create a Virtual HDD of 2.0 tB (bad idea and I don't even know how I did it)
The VHD has now reached the 1TB and can't save anything else but thinks has 2 TB.
I added a 1 tb physical and need somehow to tell Hyper V, "Hey this space is for the missing 1TB your missing"

I'm so screwed, can somene help me please.

I have a major time sensitive issue. I need to get this server online so they can work until later today I can provide a more permanent fix. The Main server 2012 has 25 GB free. When I start the vmachine it goes down to like 30MB. I moved files from the virtual machine to free 25 GB of space but that didn't effect the numbers on the main server.

Hello,

I have got in to little trouble our VM host was corrupted because of sudden power loss so i had to rebuild VM-host machine and then created new VM using hyper-v manager by attaching existing HDD, i thought i should have current user data on it but strangely it has previous user who was using this vm a month ago data on it but no data for current user who used it even last week, I still have VHDX  files from few days back in C:\Users\Public\Documents\Hyper-V\Virtual hard disks, so i was wondering is there any way if i can apply vhdx file to existing VHDD or any other way to get current user data back i have attached the picture of hyper-v HDD's
Thanks

Hi Everyone

I've set up a small Hyper-V Active Directory test lab which is isolated from our production network.  I have set it up using a separate internet line that we use for guest WiFi access.

I have the Hyper-V server on  a static IP address on a 192.168.1.xx address.

I have then created a VM running PfSense router to provide the VMs internet access and to further segregate them.  The VMs are connected to a separate Private switch that use IP addresses on 10.10.1.xx range.

I have got the basic connectivity working now, but I am just wondering if it is possible to use the PfSense to act as a VPN so I can connect into the AD domain from home etc.

I'm not looking for detailed instructions on setting it up, but just to know if its possible, or whether I need to approach it in a different way.

Cheers
Matthew

Hi,

I am in progress to install a Disaster Recovery Site with HYPER-V. The HYPER-V Hosts in Disaster Recovery Site want to be with Failover Clustering.


But to use Failover Clustering must be a member of a Domain,

So i must create a new domain name in Disaster Recovery Site for my HYPER-V Hosts? or must use the same as in Production?

I talk only for the HYPER-V Hosts not for the Virtual Machines.

Hi

We're building two identical host servers running RAID10 arrays to provide Server 2016 Hyper-V hosts and then run possibly three VM's with replication.  Assuming we are doing this purely with Microsoft at this stage, I am trying to bottom out how many licences we need to buy.  To complicate matters one of the VMs will run Server 2016 Essentials and will be DC of course. One of the other VMs will run SQL Server 2016.

So my understanding is that I will need:
1 off Server 2016 Essentials licence for the DC VM
1 off Server 2016 Standard licence for the two hosts
1 off Server 2016 Standard licence for the 1 SQL Server 2016 licence

All the reading suggests that the two Hyper-V Hosts can share one of the Server 2016 Standard licences, if they are only Hyper-V hosts and use no other roles - is this correct?  The SQL VM will need the second Server 2016 licence to run SQL Server 2016- is this correct?

Then any subsequent VMs will need their own OS licence as we build them?

Any clarification would be really helpful, as I'm going round in circles talking to Microsoft!

Thanks, C

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!

Hi,

I've just setup a Windows 2016 Server Standard with Hyper-V.  I'm using one of the VMs as a Remote Desktop Server.  The application that the users run (only 4 remote users) requires administrator elevation privileges.  I've set the compatibility on the application to always "run as administrator."  The problem is that the users only had domain user rights and when they try to run it, they get the prompt to type in an admin username and password.  This is the message:  User Account Control - "Do you want to allow this app from an unknown publisher to make changes to your device?"  I've disabled UAC to try to get that to go away but the only way I can find is to give the users administrator rights--which I don't want to do.  How have you been successful to get around this?  Thanks in advance for your advice!

Hello,

I will be deploying a new Hyper-V Server 2016 host on our domain and I am wondering if the best practices would be to join it to my domain or leave it in a workgroup.  This will be running the free Hyper-V Server core version and not Server 2016 with the Hyper-V role installed.  It would be nice to be able to manage Windows Updates and other settings via group policy, but I am wondering if joining it to the domain for this purpose is recommended since it's just the core version.  

Also, is deploying antivirus on a Hyper-V Server install recommended as well, or is it even possible on the core version?

Any information is appreciated.

Thank you

Hello all ,

    I have installed Windows Server 2016 , configured it as Hyper-V. Created a VM with Windows 10.  I would like to have the same VM into multiple VM's rather than installing everyone. Is it a way to do it?

Thanks in advance

Hello, I have a Teamed 4 port nic that is used in my Host machine.  They are used for a Virtual switch that my current VMs connect to our physical network. Here is the port configuration on my Cisco switch they plug into (all 4 ports are configured the same):

"interface GigabitEthernet1/0/29
 description Dell Server
 power inline never
 speed 1000
 duplex full
 spanning-tree portfast"

 I am visualizing a Shoretel Director physical server that needs to be on a vlan 201 and will only work if I set my CIsco port configuration to;

"interface GigabitEthernet1/0/40
 description Shoretel Server
 switchport access vlan 201
 switchport mode access"

How would I add the Switchport Access VLAN 201 to work with my current virtual switch?  
Would I change one of the 4 cisco switch ports to this setting and leave the other 3 as is?
If I change one of the Cisco ports would I create a new Virtual switch and enable the VLAN 201 for that one server?

Thanks for your help

Hi All,
I have a quick question.
can I use a single host Hyper-v Windows 2016 to setup a Hyper-converged S2D.

I Need to setup 3 servers in a Hyper-V HA environment with S2D, so I want to go with a hyper-converged options.

can anyone please confirm if this is possible.

We have several Windows 10 Hyper-V virtual machines running on a Server 2016 server. These virtual machines have all been created with a 127 GB hard drive.

We have downloaded quite a bit of data onto these virtual machines which have almost completely filled up these virtual hard drives.

Now this data has been moved to other locations or deleted and these Windows 10 virtual machines now have over 100 GB of free space. However, the sizes of these Generation 2 Windows 10 virtual machine hard drives are still quite large.

Is there any way of compacting these Generation 2 Windows 10 virtual machine hard drives so that their size will only reflect the amount of space that is actually currently being used and so that these virtual hard drive sizes won't expand again until there is more data put on these Windows 10 virtual machines? How can this be done?

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.

Thanks
Matthew
