I have a Win7 x64 host with Win7 x64 and Win10 X64 guests. The host has a PCIe TV tuner card with drivers for it, and the AMD computer IOMMU on in the BIOS. The guests have all the hardware virtualization on, and I tried the different paravirtualization modes.

In the guest, I run the driver installer and it says that there is no card found (and Device Mgr doesn't shown any unknown hardware). How do I get PCI/e passthru to work?

Thanks,
Justin

I didn't know if this was a host or a guest question.

PCI passthrough only works on Linux hosts, and even then is an experts only feature. I would have thought section 9.6 of the user manual was a must for anyone interested in this feature, and that very first sentence hard to overlook.
