I recently installed a PCIe parallel port into one of our ESXi hosts so I could migrate an old PC onto it that requires a parallel port dongle. I'm having a problem though, because I cannot add the port to a VM because the option I need is grayed out.

enter image description here

My processor does not have support for VT-d, so that option is out also. Is there no way to make use of PCI devices that are installed on the host? My NICs seem to work fine so I figured adding a parallel port shouldn't be much different.

Is there any way to get this thing working?

ESXi: 5.1
Processor: Intel E7420
Server: Dell R900
RAM: 128GB

Don't you need to configure PCI passthrough on the host, then pass the card directly to the VM? – joeqwerty Jan 9 '14 at 19:45
@joeqwerty I believe that requires VT-d – pauska Jan 9 '14 at 19:49

You're out of luck. Either downgrade to ESXi 4.1 (5.x does not support physical ports) or upgrade to a VT-d system. Or maybe find some weird paralell-over-IP system.. if you dare..
