Description
Many ltp tests ppc64le are running more than 5 hours since TW 20200520 snapshot
There was normal timing before 20200517
https://openqa.opensuse.org/tests/1281822#next_previous => from 38mn01 to >6h
https://openqa.opensuse.org/tests/1281821#next_previous => from 2mn46 to 5h18
https://openqa.opensuse.org/tests/1281830#next_previous => from 24mn37 to 5h31
https://openqa.opensuse.org/tests/1281828#next_previous => from 25mn19 to >6h
https://openqa.opensuse.org/tests/1281827#next_previous => from 10mn15 to >6h
Observation¶
openQA test in scenario opensuse-Tumbleweed-DVD-ppc64le-ltp_net_stress_ipsec_udp@ppc64le fails in
boot_ltp
Test suite description¶
Reproducible¶
Fails since (at least) Build 20200528 (current job)
Expected result¶
Last good: 20200517 (or more recent)
Further details¶

- work on one of failing test, ltp_net_stress_ipsec_udp: https://openqa.opensuse.org/tests/1279237#next_previous => from 38mn01 to >6h
- retrieve associated autoinst-log.txt as attached ./ltp_net_stress_ipsec_udp_autoinst.log
- The extracted lines show that the 301s of the "udp4_ipsec02" module
is mainly elapsed in two calls:
- wait_serial => 04:43:58.944 to 04:47:11.127 => 192s 3mn12
- wait_serial => 04:47:15.195 to 04:48:46.344 => 91s 1mn31
- so timing issue in called udp_ipsec.sh & vmstat calls for this module.
Seems that all longer tests are network related.
Probably not kernel related problem, because same 5.6.12-1-Default
for TW 20200517 that passed and 20200520 that failed:
- https://openqa.opensuse.org/tests/1272411#step/boot_ltp/3
- https://openqa.opensuse.org/tests/1274780#step/boot_ltp/3
Is it a problem on infra of Power8 hosts ?
How to execute one of them locally (outside openQA) ?

There is VIRTIO_CONSOLE=0, no surprise for that slow down. Looking for where it's set (not in test suite nor in machine).

I forgot to remove it. Added it there while fixing ppc64le failures [1] after changing console tests to use virtio_console
Updated by pvorel almost 4 years ago
- Status changed from Feedback to Resolved
@dzedro: thanks for explanation
New build is using virtio console https://openqa.opensuse.org/tests/1292396, running only 11 min instead of 28 min (3x speedup).
LTP tests will get fixed by this, closing.
