Description Ales Musil 2021-11-09 07:47:40 UTC

Description of problem:
VF creation fails on  Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection (rev 01)

Version-Release number of selected component (if applicable):
nmstate-1.2.0-0.1.alpha1.el8.noarch

Comment 3 Gris Ge 2021-11-09 08:46:41 UTC

The root cause of this bug is nmstate failure to generate the expected VF interface name.

The possible fix approach would be using the systemd-udev way on checking `/sys/class/net/<nic_name>/device/virtfn0`.

This new approach should be tested on BCM/Interl/Mellanox.

Hi Ales,

Could you check whether latest nmstate-1.2.1-0.1.alpha1.el8 fix your problem?

The is also pending 8.4/8.5 zstream regarding SR-IOV fix.
