Hi all, Recently we had several cases of OST runs that seemed to have successfully started their VMs, but ansible later failed to connect to them in the "wait_for_connection" done at start of deployment. This happened to both he-basic and basic, e.g. [1][2][3]. Some do pass, e.g. [4]. This looks like e.g. (from [1]): 20:29:58 [36m # Start vms: [32mSuccess [0m (in 0:00:02) [0m ... 20:30:08 he-basic-suite-master/test-scenarios/test_001_he_deploy.py::test_he_deploy started at 2021-07-05 17:30:08 20:30:08 -------------------------------- live log setup -------------------------------- 20:30:09 2021-07-05 17:30:09+0000,180 INFO [ost_utils.pytest.fixtures.deployment] Waiting for SSH on the VMs (deployment:60) 20:30:09 ERROR (122s)Traceback (most recent call last): ... 20:32:15 "msg": "Failed to connect to the host via ssh: ssh: connect to host 192.168.200.3 port 22: No route to host", Any idea?
