Design A: nmstate collect kernel logs 1. On verification error of SR-IOV, nmstate check `NmDeviceStateReason` to confirm whether it is a `NM_DEVICE_STATE_REASON_SRIOV_CONFIGURATION_FAILED`. 2. Parse kernel dmesg and collect all warning+ message for failed interface(matched PCI address in this case) 3. Show above kernel logs as nmstate log along with `InvalidArgument` error. |
Description of problem: When applying a desire state of nmstate setting SR-IOV `min-rx-rate` on some i40e card, user get failure like: ``` NmstateError: VerificationError: Verification failure: ens1f0.interface.ethernet.sr-iov.total-vfs desire '5', current '0' ``` This give user a wrong impression that nmstate/NetworkManager failure to activate the SR-IOV. But the actual failure is: ``` kernel: i40e 0000:3b:00.0: Invalid min tx rate (100) (greater than 0) specified for VF 2. ``` When NetworkManager failed to set SR-IOV parameters, NM will disable SRIOV setting which lead to nmstate found SR-IOV been disabled during verification stage. Version-Release number of selected component (if applicable): nmstate-2.2.10-3.el9 How reproducible: 100% Steps to Reproduce: 1. Apply this desire state on i40e card which does not support setting `min-tx-rate`: ``` interfaces: - name: ens1f0 type: ethernet description: Change QOS on VF0 state: up ethernet: sr-iov: total-vfs: 5 vfs: - id: 2 min-tx-rate: 100 max-tx-rate: 200 ``` Actual results: VerificationError: Verification failure: ens1f0.interface.ethernet.sr-iov.total-vfs desire '5', current '0' Expected results: InvalidArgument: Invalid SR-IOV parameter for interface ens1f0: kernel: i40e 0000:3b:00.0: Invalid min tx rate (100) (greater than 0) specified for VF 2.
