"tempest.scenario.test_volume_boot_pattern.TestVolumeBootPatternV2.test_volume_boot_pattern" failed with SSH timeout

[Michael Berlin]

Hi,

I'm new to OpenStack development and got this in one of my first patchsets. It looks like a typical flaky test?

"check-tempest-dsvm-postgres-full" failed because of "SSHTimeout: Connection to the 172.24.4.20 via SSH timed out." error in "tempest.scenario.test_volume_boot_pattern.TestVolumeBootPatternV2.test_volume_boot_pattern"

See: http://logs.openstack.org/11/94211/1/check/check-tempest-dsvm-postgres-full/a36c291/

Review which triggered the test: https://review.openstack.org/#/c/94211/ (I've only changed a unit test. This shouldn't cause the error)

Possible duplicate bugs may be: #1298472 and #1253896 (However, my error output seems to be unique and I haven't found it somewhere else yet.)

Output of the failed test:
