  Afterward, run `lspci -nnks 28:00` to check that the driver loaded correctly. If everything went well, for each device we should see:

  Congratulations! We have our PVE server configured and ready to use. We can now begin link:https://pve.proxmox.com/wiki/VM_Templates_and_Clones[creating Virtual Machines (VMs)^] or link:https://pve.proxmox.com/wiki/Linux_Container[Containers^]. In future posts, we'll consider additional opportunties for enhancing performance and security for our server, VMs, and Containers. 
  
  Although we have configured passthrough on the server, updates to our VMs are required to leverage that feature. Because Nvidia sells a commercial line of GPUs (Quadro), they do not _support_ passthrough, and actively try to inhibit passthrough on their consumer line (GeForce). We will have to consider potential workarounds to enable that functionality, which may involve future tweaks to our server settings.
