The following tests fail after switching from RHEL 7.3 to RHEL 7.4 *neutron.tests.functional.agent.test_firewall.FirewallTestCase.test_dhcp_server_forbidden_on_vm(IptablesFirewallDriver,without ipset) *neutron.tests.functional.agent.test_firewall.FirewallTestCase.test_ingress_icmp_secgroup(IptablesFirewallDriver,with ipset) This is *probably* happening because iptables-1.4.21-18.el7.x86_64 (which installed with RHEL 7.4 but not former releases) introduced new file lock mechanism that used by all iptables commands. To adjust current commands to new iptables, we probably need to add "--wait" so the execution will wait for the lock instead of existing. Version-Release number of selected component (if applicable): openstack-neutron-7.2.0-12.1.el7ost.noarch openstack-neutron-common-7.2.0-12.1.el7ost.noarch openstack-neutron-openvswitch-7.2.0-12.1.el7ost.noarch How reproducible: 100% Steps to Reproduce: 1. Clone neutron repository 2. Run functional tests (tox -e dsvm-functional) Actual results: tests failed Expected results: tests passed successfully Additional info: fails on RHEL 7.4 only
Jakub will take a look. Also possible it's happening on 12.
