Hi, I have a x520 pcie network card with 2 nics, The vfio-pci.ids method worked fine (I passed through those to xpenology). But when I try this plugin, the xpenology can no longer get an ip address. I checked lspci -v in unraid and it seems that unraid loaded the network card with vfio-pci, so I suppose they should be passed through. 07:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Netwo rk Connection (rev 01) Subsystem: Intel Corporation Ethernet Server Adapter X520-2 Flags: fast devsel, IRQ 11 Memory at f2100000 (64-bit, non-prefetchable) [disabled] [size=512K] I/O ports at 9020 [disabled] [size=32] Memory at f2200000 (64-bit, non-prefetchable) [disabled] [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [50] MSI: Enable- Count=1/1 Maskable+ 64bit+ Capabilities: [70] MSI-X: Enable- Count=64 Masked- Capabilities: [a0] Express Endpoint, MSI 00 Capabilities: [e0] Vital Product Data Capabilities: [100] Advanced Error Reporting Capabilities: [140] Device Serial Number 00-1b-21-ff-ff-ba-e9-ba Capabilities: [150] Alternative Routing-ID Interpretation (ARI) Capabilities: [160] Single Root I/O Virtualization (SR-IOV) Kernel driver in use: vfio-pci Kernel modules: ixgbe 07:00.1 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Netwo rk Connection (rev 01) Subsystem: Intel Corporation Ethernet Server Adapter X520-2 Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at f2180000 (64-bit, non-prefetchable) [size=512K] I/O ports at 9000 [size=32] Memory at f2404000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [50] MSI: Enable- Count=1/1 Maskable+ 64bit+ Capabilities: [70] MSI-X: Enable+ Count=64 Masked- Capabilities: [a0] Express Endpoint, MSI 00 Capabilities: [e0] Vital Product Data Capabilities: [100] Advanced Error Reporting Capabilities: [140] Device Serial Number 00-1b-21-ff-ff-ba-e9-ba Capabilities: [150] Alternative Routing-ID Interpretation (ARI) Capabilities: [160] Single Root I/O Virtualization (SR-IOV) Kernel driver in use: vfio-pci Kernel modules: ixgbe And here is the output of lspci -v in xpenology(I select only one nic to xpenology): 0000:04:00.0 Class 0200: Device 8086:10fb (rev 01) Subsystem: Device 8086:000c Flags: bus master, fast devsel, latency 0, IRQ 23 Memory at 98200000 (64-bit, non-prefetchable) [size=512K] I/O ports at 7000 [size=32] Memory at 98280000 (64-bit, non-prefetchable) [size=16K] Capabilities: [40] Power Management version 3 Capabilities: [50] MSI: Enable- Count=1/1 Maskable+ 64bit+ Capabilities: [70] MSI-X: Enable+ Count=64 Masked- Capabilities: [a0] Express Endpoint, MSI 00 Capabilities: [e0] Vital Product Data Capabilities: [100] Advanced Error Reporting Capabilities: [140] Device Serial Number 00-1b-21-ff-ff-ba-e9-ba Kernel driver in use: ixgbe I'm kind of confused. It seems both unraid and xpenology is showing the driver correctly, but no ip address for the nic. Everything worked just fine using vfio-pci.ids method but I just want to try if I could pass only one nic and leave the other one. I will attach the diagnostics below. I made some further effort trying the xen-pciback.hide method, which uses pci ids instead of vendor ids so that I could pass only one of the two nics. And it works. So i guess this might be some bug in vfio-pci config plugin. tower-diagnostics-20200424-2248.zip
