Red Hat Satellite engineering is moving the tracking of its product development work on Satellite 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 "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. 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 "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-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 Roman Bobek 2017-05-25 08:57:04 UTC 
Description of problem:
Booting of PXE less discovery image is failing with network initialization error, because of slow DHCP network. 

How reproducible:
On customers side.

Steps to Reproduce:
1. create a discovery image
2. boot the server
3. wait for error

Actual results:
Boot fails with network initialization error.

Expected results:
Discovery image will boot.

Additional info:
Adding sleep(15) at the top of the configure_network function workarounds the issue. According to lzap we should include delay feature to PXE less initialization, same as we have in PXE initialization.

Lukas, thoughts on this one?
Comment 2 Lukas Zapletal 2017-05-29 08:15:43 UTC 
Roman I can indeed implement the fix but I cannot reproduce, can you send me full logs from the discovered node when you encounter this kind of error? The script is called discovery-debug, send me output of this to the BZ.
Comment 3 Lukas Zapletal 2017-06-05 11:20:47 UTC 
I am asking because I don't understand, in PXE-less mode there is plenty of time if you go screen by screen. Do you mean semi-automatic or full-automatic (unattended) mode when you enter all the details on the kernel command line? What was your setting then? I need to know before I can put the delay.

I have asked for the logs, but the customer unfortunately does not have the HW to reproduce this issue.

Have asked him for more details about booting mode and settings. Waiting for the reply.
Comment 5 Lukas Zapletal 2017-06-07 10:26:58 UTC 
The error message from the attached image is triggered by this statement:

    nmcli connection down primary

this happens when the primary connection is brought down and it was not yet brought up. So the error is expected in this case. It's just a cosmetic issue and it has no effect.

I filed this upstream: http://projects.theforeman.org/issues/19950

We will eventually fix this, no backport or QA needed for this one, closing.

Sorry, this was a different issue. Re-opening:

Comment 8 Satellite Program 2017-06-13 20:12:34 UTC 
Moving this bug to POST for triage into Satellite 6 since the upstream issue http://projects.theforeman.org/issues/19984 has been resolved.
Comment 9 Lukáš Hellebrandt 2017-12-21 10:15:14 UTC 
Verified with foreman-discovery-image-3.4.1-3.iso.

There is no clear reproducer for the issue so I did the following:
1) Used FDI to discover a host which worked correctly
2) Verified the change was actually present on the ISO in /usr/lib64/ruby/vendor_ruby/discovery/menu.rb
3) The error "nmcli connection down" is not present in journalctl

Note: waiting for a magic constant "10 seconds" is fishy, it would be better to wait in a loop
