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.

This was filed against fedora 23 version, but by the upstream discussion this sounds relevant to libvirt.git as well, and it affects openstack, so worth considering for RHEL.


+++ This bug was initially created as a clone of Bug #1372944 +++

Description of problem:
Due to this commit cb3fe38c  (which supposed to fix this bug https://bugzilla.redhat.com/show_bug.cgi?id=1113474) libvirt is now setting the mac on the VF using netlink RTM_SETLINK but not on the VF's netdev name.
For macvtap-passthrough we need the mac to be set both on VF's netdev name and using the VF using netlink RTM_SETLINK.

Version-Release number of selected component (if applicable):
libvirt-1.2.18.3-1.fc23.x86_64

How reproducible:
create a guest with macvtap-passthrough in openstack
The guest will not get DHCP because the the VF's netdev name is not set.


Actual results:
guest didn't get DHCP

Expected results:
guest should get DHCP

Hmm. How did I previously miss that this is the same as Bug 1415609. Could have saved the trouble of filing that one.

Anyway there is now a lot of comment/info in there, so I'm closing this bug as a duplicate of that one (which will be fixed - half of the patches are already pushed, and the other half waiting for one more ACK).
