Description of problem: There is a bug in the function wait_for_guest_os_ready which we hit when running neutron tempest tests while tempest config compute_feature_enabled.console_output set to False. With console_output set to True we do not hit the bug but test execution is very slow for tests where we launch more than 1 VM because each VM is spawned after previous one is fully booted. this causes that some downstream multicast tests which are spawning 3+ VMs are very slow. Note: with console_output set to False we are able to launch all 3-5 VMs simultaneously. All VMs are up after less than a minute. Version-Release number of selected component (if applicable): python3-neutron-tests-tempest-0.9.0-1.20201113201946.el8ost.noarch How reproducible: 100% Steps to Reproduce: 1. Set tempest config value compute_feature_enabled.console_output to False 2. Run any test that uses wait_for_guest_os_ready, e.g. test_multicast_between_vms_on_same_network Actual results: Test fails on wrong index Expected results: Test passes Additional info:
Verified on RHOS-16.1-RHEL-8-20210413.n.0 python3-neutron-tests-tempest-0.9.0-1.20210329083504.15c85f6.el8ost.noarch contains the fix, now it's possible to run neutron tempest tests with console_output=False
