Hi there, I've recently bought Windows 8. The first thing I've noticed is that there is no Hyper-V support for my CPU (Intel Core2Duo T8100) because of the missing SLAT, which is totally idiotic!
I've managed to install Hyper-V with PowerShell, but when I tried to start Windows 2012 VM, a message is popping up to tell me that the hypervisor is not running! I've checked with CoreInfo and it is true. The hypervisor is not present.
I am sure that DEP and VT-x are enabled in my BIOS, and that the hypervisorlaunchtype is set to auto in the BCD. Checked both statuses with a program called securable, or something like this. The only thing that I was able to find out is that there is a single error in the event log saying tat ' The virtualization infrastructure driver (VID) is not running.'
. I thought that there is a difference between Windows 2012 Hyper-V (not requiring SLAT) and the Windows 8 one, but there isn't (checked files one by one). Any ideas that may help me resolve this issue will be greatly appreciated.
To add to Ted's reply - it does. And to add to your investigation - yes, it is 100% the same Hyper-V hypervisor.
Client imposes this and the hypervisor will not start without it. You can PowerShell and DISM all you want on Windows 8 and you can manage to install Hyper-V but it will not run without SLAT. Do what I do - Install Windows Server 2012 on your laptop, add Desktop Experience, wireless, etc. And then create a second local admin account. Login with the second local admin account and poof, you have the Windows Store.
The graphic experience is not as high as the SLAT requirement is trying to dictate - but the rest of the experience is all there. Brian Ehlert Learn. Disclaimer: Attempting change is of your own free will. 'Windows 8' = 'Client' operating system, designed for end user workstations.
'Server 2012' = 'Server' operating system, designed for infrastructure workloads, application servers, etc. It just happens to have 'client' features to support Remote Desktop Sessions (formerly Terminal Services). Unfortunately, a decision was made and reinforced around the SLAT requirement.
And you are not the first, you won't be the last either, to complain. That was an MSFT decision. Brian Ehlert Learn.

More specifically can the RD Connection Broker role service be installed on the free Hyper-V Server 2012 R2? Microsoft suggest it can and push Hyper-V Server 2012 R2 as a good choice for VDI infrastructure. However I can't get RD Connection Broker role service to install on any Hyper-V Server 2012 R2 boxes. I have established that the problem seems to be WID, Windows Internal Database, which RD Connection Broker requires but is not a feature which can be installed on Hyper-V Server 2012 R2. So what is the situation should it install or not?

It's a breach of licence and no it doesn't make a mockery of Microsoft's comment. Hyper-V is a Type-1 HYPERVISOR. It's sole job is to run the infrastructure to host virtual machines.
The Virtual machines can host the VDI infrastructure. Hyper-V can do some very cool things in ensuring that the uptime is as good as possible thanks to things like clustering hence Hyper IS useful in VDI infrastructures. Not for running them directly but for hosting the VM's that do.
Performance Tuning Remote Desktop Virtualization Hosts. 12 minutes to read.
Contributors. In this article Remote Desktop Virtualization Host (RD Virtualization Host) is a role service that supports Virtual Desktop Infrastructure (VDI) scenarios and lets multiple concurrent users run Windows-based applications in virtual machines that are hosted on a server running Windows Server 2016 and Hyper-V. Windows Server 2016 supports two types of virtual desktops, personal virtual desktops and pooled virtual desktops. In this topic:. General considerations Storage Storage is the most likely performance bottleneck, and it is important to size your storage to properly handle the I/O load that is generated by virtual machine state changes.
If a pilot or simulation is not feasible, a good guideline is to provision one disk spindle for four active virtual machines. Use disk configurations that have good write performance (such as RAID 1+0). When appropriate, use Disk Deduplication and caching to reduce the disk read load and to enable your storage solution to speed up performance by caching a significant portion of the image.
Data Deduplication and VDI Introduced in Windows Server 2012 R2, Data Deduplication supports optimization of open files. In order to use virtual machines running on a deduplicated volume, the virtual machine files need to be stored on a separate host from the Hyper-V host. If Hyper-V and deduplication are running on the same machine, the two features will contend for system resources and negatively impact overall performance.
The volume must also be configured to use the “Virtual Desktop Infrastructure (VDI)? Deduplication optimization type.
You can configure this by using Server Manager ( File and Storage Services - Volumes - Dedup Settings) or by using the following Windows PowerShell command: Enable-DedupVolume -UsageType HyperV Note Data Deduplication optimization of open files is supported only for VDI scenarios with Hyper-V using remote storage over SMB 3.0. Memory Server memory usage is driven by three main factors:. Operating system overhead. Hyper-V service overhead per virtual machine. Memory allocated to each virtual machine For a typical knowledge worker workload, guest virtual machines running x86 Window 8 or Windows 8.1 should be given 512 MB of memory as the baseline.
However, Dynamic Memory will likely increase the guest virtual machine’s memory to about 800 MB, depending on the workload. For x64, we see about 800 MB starting, increasing to 1024 MB. Therefore, it is important to provide enough server memory to satisfy the memory that is required by the expected number of guest virtual machines, plus allow a sufficient amount of memory for the server. CPU When you plan server capacity for an RD Virtualization Host server, the number of virtual machines per physical core will depend on the nature of the workload.
As a starting point, it is reasonable to plan 12 virtual machines per physical core, and then run the appropriate scenarios to validate performance and density. Higher density may be achievable depending on the specifics of the workload. We recommend enabling hyper-threading, but be sure to calculate the oversubscription ratio based on the number of physical cores and not the number of logical processors.
This ensures the expected level of performance on a per CPU basis. Virtual GPU Microsoft RemoteFX for RD Virtualization Host delivers a rich graphics experience for Virtual Desktop Infrastructure (VDI) through host-side remoting, a render-capture-encode pipeline, a highly efficient GPU-based encode, throttling based on client activity, and a DirectX-enabled virtual GPU. RemoteFX for RD Virtualization Host upgrades the virtual GPU from DirectX9 to DirectX11. It also improves the user experience by supporting more monitors at higher resolutions. The RemoteFX DirectX11 experience is available without a hardware GPU, through a software-emulated driver.
Although this software GPU provides a good experience, the RemoteFX virtual graphics processing unit (VGPU) adds a hardware accelerated experience to virtual desktops. To take advantage of the RemoteFX VGPU experience on a server running Windows Server 2016, you need a GPU driver (such as DirectX11.1 or WDDM 1.2) on the host server. For more information about GPU offerings to use with RemoteFX for RD Virtualization Host, contact your GPU provider. If you use the RemoteFX virtual GPU in your VDI deployment, the deployment capacity will vary based on usage scenarios and hardware configuration. When you plan your deployment, consider the following:. Number of GPUs on your system. Video memory capacity on the GPUs.
Processor and hardware resources on your system RemoteFX server system memory For every virtual desktop enabled with a virtual GPU, RemoteFX uses system memory in the guest operating system and in the RemoteFX-enabled server. The hypervisor guarantees the availability of system memory for a guest operating system. On the server, each virtual GPU-enabled virtual desktop needs to advertise its system memory requirement to the hypervisor. When the virtual GPU-enabled virtual desktop is starting, the hypervisor reserves additional system memory in the RemoteFX-enabled server for the VGPU-enabled virtual desktop. The memory requirement for the RemoteFX-enabled server is dynamic because the amount of memory consumed on the RemoteFX-enabled server is dependent on the number of monitors that are associated with the VGPU-enabled virtual desktops and the maximum resolution for those monitors. RemoteFX server GPU video memory Every virtual GPU-enabled virtual desktop uses the video memory in the GPU hardware on the host server to render the desktop.
In addition to rendering, the video memory is used by a codec to compress the rendered screen. The amount of memory needed is directly based on the amount of monitors that are provisioned to the virtual machine. The video memory that is reserved varies based on the number of monitors and the system screen resolution.
Some users may require a higher screen resolution for specific tasks. There is greater scalability with lower resolution settings if all other settings remain constant. RemoteFX processor The hypervisor schedules the RemoteFX-enabled server and the virtual GPU-enabled virtual desktops on the CPU. Unlike the system memory, there isn’t information that is related to additional resources that RemoteFX needs to share with the hypervisor. The additional CPU overhead that RemoteFX brings into the virtual GPU-enabled virtual desktop is related to running the virtual GPU driver and a user-mode Remote Desktop Protocol stack.

On the RemoteFX-enabled server, the overhead is increased, because the system runs an additional process (rdvgm.exe) per virtual GPU-enabled virtual desktop. This process uses the graphics device driver to run commands on the GPU. The codec also uses the CPUs for compressing the screen data that needs to be sent back to the client. More virtual processors mean a better user experience. We recommend allocating at least two virtual CPUs per virtual GPU-enabled virtual desktop. We also recommend using the x64 architecture for virtual GPU-enabled virtual desktops because the performance on x64 virtual machines is better compared to x86 virtual machines.
The Virtualization Infrastructure Driver Vid Is Not Running Server 2012
RemoteFX GPU processing power For every virtual GPU-enabled virtual desktop, there is a corresponding DirectX process running on the RemoteFX-enabled server. This process replays all the graphics commands that it receives from the RemoteFX virtual desktop onto the physical GPU. For the physical GPU, it is equivalent to simultaneously running multiple DirectX applications. Typically, graphics devices and drivers are tuned to run a few applications on the desktop.
RemoteFX stretches the GPUs to be used in a unique manner. To measure how the GPU is performing on a RemoteFX server, performance counters have been added to measure the GPU response to RemoteFX requests. Usually when a GPU resource is low on resources, Read and Write operations to the GPU take a long time to complete.
