Tutorial: Passing through GPU to Hyper-V guest VM

.\Update-VMGpuPartitionDriver.ps1 -VMName "GPUPV" -GPUName "AUTO" (it picked the wrong gpu,anyway)

at this point I tried to help the script to pick the right GPU :

.\Update-VMGpuPartitionDriver.ps1 -VMName "GPUPV" -GPUName "NVIDIA GeForce RTX 2080 Ti"

then :

nano new.ps1

$vm = "GPUPV"
if (Get-VMGpuPartitionAdapter -VMName $vm -ErrorAction SilentlyContinue) {
Remove-VMGpuPartitionAdapter -VMName $vm
}
Set-VM -GuestControlledCacheTypes $true -VMName $vm
Set-VM -LowMemoryMappedIoSpace 1Gb -VMName $vm
Set-VM -HighMemoryMappedIoSpace 32Gb -VMName $vm
Add-VMGpuPartitionAdapter -VMName $vm

and :

.\new.ps1
ok

the result is totally wrong :

Sorry I'm not sure what went wrong.

It looks like it copied the wrong drivers anyway. You manually specified "NVIDIA GeForce RTX 2080 Ti" but the VM is seeing "GeForce 1060 3gb"

I made some progress,but it still does not work as expected. This is what I did :

1) created a new Hyper-V VM called "Windows11-GNUP"
2) .\Update-VMGpuPartitionDriver.ps1 -VMName "Windows-11-GNUP" -GPUName "NVIDIA GeForce RTX 2080 Ti"
3) nano new.ps1

$vm = "Windows-11-GNUP"
if (Get-VMGpuPartitionAdapter -VMName $vm -ErrorAction SilentlyContinue) {
Remove-VMGpuPartitionAdapter -VMName $vm
}
Set-VM -GuestControlledCacheTypes $true -VMName $vm
Set-VM -LowMemoryMappedIoSpace 1Gb -VMName $vm
Set-VM -HighMemoryMappedIoSpace 16Gb -VMName $vm
Add-VMGpuPartitionAdapter -VMName $vm

4) .\new.ps1

this is what happened :




it attached the GTX 1060 and not the RTX 2080 ti,but anyway,the drivers have been copied correctly. Infact I can launch Blender and Cycles has been able to recognize the CUDA libraries and the GPU. It's a shame that's the wrong one. Maybe with two GPUs,the script confuses itself.

Hmmmm ok interesting. Maybe creating the new VM caused it to be a Generation 2 VM? Because Generation 2 VM is required. I also see that you changed the high memory mapped in the script

Yes, I have already chosen "generation 2" VM. And yes,I have chosen 16 GB of the default 32 Gb for caution. Could this be the reason?

i cannot say for sure

ok. the important thing is that it worked. Anyway,I'm more interested to use Linux instead of Windows. I'm studying the script and the situation to understand if I can get the same result (such as the cuda libraries and my gpu recognized) using Linux. I have some ideas about how to achieve the same result. If someone wants to collaborate,I'm here.

you can try to modify your script like this one :

Code:

$vm = "ubuntu"
Remove-VMGpuPartitionAdapter -VMName $vm
$gpu_list = Get-VMHostPartitionableGpu
foreach ($k in $gpu_list){
    $instance_path = $k.Name
    $instance_path
    Add-VMGpuPartitionAdapter -VMName $vm -InstancePath $instance_path
}
Set-VMGpuPartitionAdapter -VMName $vm -MinPartitionVRAM 1
Set-VMGpuPartitionAdapter -VMName $vm -MaxPartitionVRAM 11
Set-VMGpuPartitionAdapter -VMName $vm -OptimalPartitionVRAM 10
Set-VMGpuPartitionAdapter -VMName $vm -MinPartitionEncode 1
Set-VMGpuPartitionAdapter -VMName $vm -MaxPartitionEncode 11
Set-VMGpuPartitionAdapter -VMName $vm -OptimalPartitionEncode 10
Set-VMGpuPartitionAdapter -VMName $vm -MinPartitionDecode 1
Set-VMGpuPartitionAdapter -VMName $vm -MaxPartitionDecode 11
Set-VMGpuPartitionAdapter -VMName $vm -OptimalPartitionDecode 10
Set-VMGpuPartitionAdapter -VMName $vm -MinPartitionCompute 1
Set-VMGpuPartitionAdapter -VMName $vm -MaxPartitionCompute 11
Set-VMGpuPartitionAdapter -VMName $vm -OptimalPartitionCompute 10
Set-VM -GuestControlledCacheTypes $true -VMName $vm
Set-VM -LowMemoryMappedIoSpace 1Gb -VMName $vm
Set-VM -HighMemoryMappedIoSpace 32GB -VMName $vm

instead of this one :

Code:

$vm = "Name of your VM"
if (Get-VMGpuPartitionAdapter -VMName $vm -ErrorAction SilentlyContinue) {
   Remove-VMGpuPartitionAdapter -VMName $vm
}
Set-VM -GuestControlledCacheTypes $true -VMName $vm
Set-VM -LowMemoryMappedIoSpace 1Gb -VMName $vm
Set-VM -HighMemoryMappedIoSpace 32Gb -VMName $vm
Add-VMGpuPartitionAdapter -VMName $vm

is there any considerations for updating video drivers? I would like to update mine on my host os.

As far as I understand, everytime you update your graphics drivers on your host, you will similarly need to copy those new drivers into the guest VMs as well. We simply repeat Step 4 to do this.
