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.

How reproducible:
Always
Steps to Reproduce:
1. boot a new machine
2. wait to finish boot
3. try to login
Actual results:
During boot, this exception is thrown:
2018-01-15 11:44:01,750 - util.py[WARNING]: failed stage init-local
failed run of stage init-local

if isinstance(subnet['dns_search'], (list, tuple)):
KeyError: 'dns_search'
------------------------------------------------------------
Expected results:
Instance should have an IP assigned
Additional info:
I now that our openstack instance is very old, but the fix is really simple:
in /usr/lib/python2.7/site-packages/cloudinit/net/sysconfig.py, line 368, just check if the key exists first:
if 'dns_search' in subnet and isinstance(subnet['dns_search'], (list, tuple)):
Thanks for catching this. This looks like a typo introduced as part of the fix for Bug 1489270, so I am going to dupe it into that.
