August 28, 20241 yr Hello, I don't know if the title is correct but I wouldn't know where my issue is to describe it. I added an Ethernet card that is detected in System Devices (Ethernet controller: Cavium, Inc. CN23XX [LiquidIO II] Intelligent Adapter (rev 03)) But it's not showing in network settings. What am I missing? Added diagnostics Thanks! *edit: running the following command, it became clear that I am missing drivers. I am still not sure how to proceed lspci -nnk | grep -A2 Ethernet tower-diagnostics-20240829-0109.zip Edited August 29, 20241 yr by thedoc
August 29, 20241 yr Community Expert There's no driver for this NIC, this appears to be an older model, is this gigabit or 100Mbit?

August 29, 20241 yr Community Expert You can make a feature request to see if the driver can be added.
August 29, 20241 yr Author Thanks I will, but is there an alternative? I mean there isn't a general interest in these drivers probably. Can I install them on my own some way?
September 7, 20241 yr Author I don't know if I have to open another thread, but I tried to passthrough the device to a VM and I got the following error Quote internal error: qemu unexpectedly closed the monitor: qxl_send_events: spice-server bug: guest stopped, ignoring 2024-09-07T13:18:43.389954Z qemu-system-x86_64: -device {"driver":"vfio-pci","host":"0000:01:00.0","id":"hostdev0","bus":"pci.0","addr":"0x8"}: vfio 0000:01:00.0: hardware reports invalid configuration, MSIX PBA outside of specified BAR On bios, I changed the PCI Gen from auto to Gen5 to no avail (it's placed in Gen5 X16 slot, tried X16 slot running x4 too).

Done some seraching not found an answer as yet, but the above section says BAR it 512GB so not sure if that is the reason.
September 8, 20241 yr Community Expert No sure if this can be set for the card. <driver name='vfio' msix='off'/>
