Hi all, This is not the first time this test fails, but it is a rare failure. Anyone has a clue why it fails? According the captured log, all the ip runs are successful. Can it be an issue on specific slave? 21:25:25 ====================================================================== 21:25:25 FAIL: testEnablePromisc (ipwrapperTests.TestDrvinfo) 21:25:25 ---------------------------------------------------------------------- 21:25:25 Traceback (most recent call last): 21:25:25 File "/home/jenkins/workspace/vdsm_master_check-patch-fc23-x86_64/vdsm/tests/ipwrapperTests.py", line 130, in testEnablePromisc 21:25:25 "Could not enable promiscuous mode.") 21:25:25 AssertionError: Could not enable promiscuous mode. 21:25:25 -------------------- >> begin captured logging << -------------------- 21:25:25 root: DEBUG: /usr/bin/taskset --cpu-list 0-1 /usr/sbin/brctl show (cwd None) 21:25:25 root: DEBUG: SUCCESS: <err> = ''; <rc> = 0 21:25:25 root: DEBUG: /usr/bin/taskset --cpu-list 0-1 /sbin/ip link add name vdsm-ooqBPb type bridge (cwd None) 21:25:25 root: DEBUG: SUCCESS: <err> = ''; <rc> = 0 21:25:25 root: DEBUG: /usr/bin/taskset --cpu-list 0-1 /sbin/ip link set dev vdsm-ooqBPb up (cwd None) 21:25:25 root: DEBUG: SUCCESS: <err> = ''; <rc> = 0 21:25:25 root: DEBUG: /usr/bin/taskset --cpu-list 0-1 /sbin/ip link set dev vdsm-ooqBPb promisc on (cwd None) 21:25:25 root: DEBUG: SUCCESS: <err> = ''; <rc> = 0 21:25:25 --------------------- >> end captured logging << --------------------- See http://jenkins.ovirt.org/job/vdsm_master_check-patch-fc23-x86_64/1101/consol...
