Task viewer: VM 100 - Start

OutputStatus

Stop
kvm: -device vfio-pci,host=0000:02:00.0,id=hostpci1,bus=pci.0,addr=0x11: vfio 0000:02:00.0: device is already attached

You are trying to passthrough the same NIC two times.
First you passthrough "00:02:00" wich will passthrough the complete NIC with poth ports. Then you use "00:02:00.1" which will pasthrough one of the two ports of your NIC.

If you just want to passthrough one port for WAN either use "00:02:00.1" or "00:02:00.0" only.
If you want to passthrough both ports just use "00:02:00" and check the "all functions" checkbox.

Adding both individual functions might work fine (like in your screenshots) but not all NICs allow to seperate the functions. In such a case it would be better to only add "0000.02.00.0" OR "0000.02.00.1" but with the "All functions" (see your screenshot where it is not checked) checked which should result in a single "0000.02.00" entry that will passthrough the whole NIC with both functions/ports.
