I am having some serious troubles passing through my NIC to my Windows guest running on KVM.
The current driver in use is vfio-pci and I have done the passthrough via Virt-Manager so the XML format is correct. But when I try to start it, it shows Internal Error: Unknown PCI Header Type 127.
lspci -nnv shows Unknown Header Type 7F
02:00.0 Network controller [0280]: Intel Corporation Wireless 8260 [8086:24f3] (rev ff) (prog-if ff)
!!! Unknown header type 7f
Kernel driver in use: vfio-pci
Kernel modules: iwlwifi
Does anybody have any advice/experience passing through an Intel PCI WiFi NIC on KVM that could possibly help? Thanks.
PS: This device has been successfully pass through w/ ESXi and currently I have passthrough working with my GPU, so you can count vt-d/iommu configuration out of the equation. (And hardware failure, I think. The only real way for me to test is to get this working on KVM or go back to ESXi and if it doesn't work on ESXi then its broken). I have been switching hypervisors for testing a lot latley and I'm hoping to get this to work with KVM, i suspect its not broken hardware that is the issue.
