Discrete Device Assignment for Hyper V issues

Hello everyone,

I hope everyone doing great.
I have Nvidia A40 (Model GA102GL [A40]). I am Deploy graphics devices using


VMs. After I attached graphic card to VM, install the driver for Nvidia A40 and I got this error :

This device cannot find enough free resources that it can use. (Code12).

If you want to use this device, you will need to disable one of the other devices on this system.

**** I disabled and uninstalled HyperV graphic card on this VMm reboot and still not working. Any suggestion? Thanks

SR-IOV enabled on the host? A40 requires SR-IOV…

Did you also play with these?

set-vm -vmname $vmname -GuestControlledCacheTypes $true
Set-VM -LowMemoryMappedIoSpace 3Gb -VMName $vmname
Set-VM -HighMemoryMappedIoSpace 64Gb -vmname $vmname
