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 Pavel Cahyna 2021-01-11 18:31:16 UTC 
Description of problem:

After running tests_bond_initscripts, which uses dnsmasq as a dns/dhcp server on the bond interface, resolv.conf contains:

; generated by /usr/sbin/dhclient-script
nameserver 192.0.2.1

which is probably the IP address of dnsmasq, which is no longer running.

As a consequence, DNS is broken in the test VM and all other tests that need to download packages fail. Among them tests_unit.yml and all the storage role tests, also some selinux tests (need to install policycoreutils-python).

Version-Release number of selected component (if applicable):

rhel-system-roles-1.0-22.el8

How reproducible:

well, in 1minutetip.

Steps to Reproduce:
1. 1minutetip -p ANSIBLE_VER=2 -p "SYSTEM_ROLES_ONLY_TESTS=network/tests_bond_initscripts.yml network/tests_unit.yml" rhel8

Actual results:

tests_unit.yml fails. Can not dowload Packages/python2-mock.

Expected results:

tests_unit.yml succeeds.

Additional info:

This is not a regression in the role, because the 8.3 package in 8.4 has the same problem and the 8.4 package in 8.3 does not have the problem. Something has changed in the meantime and I was not able to identify it: I tried downgrading NetworkManager, dhcp-client, network-scripts, dnsmasq, to their 8.3 versions, always with thesame result.
Comment 4 Till Maas 2021-02-24 15:25:32 UTC 
Idea about a possible solution: Maybe the profiles used for the tests with dhcp can be adjusted to ignore DNS settings.
Comment 7 Gris Ge 2021-07-14 15:46:43 UTC 
Patch send to upstream.
