RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

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.
