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 Christophe Besson 2021-08-31 12:32:45 UTC 
Description of problem:
Customer falls in the emergency shell in one of the last step of the upgrade (persistentnamingconfig). They have an ixgbe NIC with several VFs enabled on the host. Originally they enabled it with a "homemade fashion" by doing some echoes into /sys from the rc.local boot script. We suggested to change their approach by enabling it thanks to an udev rule, but they claim that leads to the same issue.

Version-Release number of selected component (if applicable):
leapp-repository-0.12.0-2.el7_9.noarch

How reproducible:
100% for the customer.
Unable to reproduce without the HW.

Comment 3 Christophe Besson 2021-08-31 12:33:47 UTC 
the suggested workaround for now is to disable SR-IOV on the host.
Comment 6 Petr Stodulka 2021-08-31 15:55:57 UTC 
Hi Chris. Thanks for the report. The issue has been already fixed in leapp-repository-0.13.0 (the current supported version of leapp-repository is 0.14.0 right now). Closing the BZ.

Hi Petr,

oh ok, I didn't think it was the same root cause.
Thanks for your feedback!
