Hi, i am trying to configure an ESXI 6.5 to use some National Instrument PCI cards in a virtualized environment. I had a lot of problems so far, caused by the design of my system: The computer on which ESXI is installed is also the client machine which permit to use some P2V VM with National Instrument PCI carde using Passthru.
The structure work fine, I have acces to ESXI, my master VM, and my P2V VMs on the same machine (and the same screen).
I’m using a PCIe-Q370-r11 Motherboard with a PXE-13S-r50 backplane (8 Pci slots divided in two bridges, 4 Pcie slot.
Actually i’m using 4 pci and 2 pcie slots:
- Gpu Quadro P2000 and USB controller with passthrough to the master VM
- 4 National Instrument pci cards with passthrough to the P2V Vm.
Problem: Passthrough works fine on all VMs, I can start all of them. But on the P2V Vms, PCI cards don’t work. Windows know they’re here, drivers seems to be installed correctly, National Instrument software also detect them correctly.
When I go using lspci on my ESXI, those cards are marqued as ´´Class FF00’´ (Unassigned class). They are all on the same PCI bridge. The cards names are correct, their ID seems OK too. But the cards Serial Number won’t show up in my VM.
I don’t get it why it’s behaving like this.
The PCI cards are not unknown to ESXI, but for some reason, they are not correctly used by VMs.
Maybe a problem with pci bridge's drivers? Or pci.ids incorrect?
If anybody had this issue before, i’ll be happy to hear it!
Thanks for reading the entire post with my terrible English level
