Open Stack

Hi,

This is ssh timeout issue happened. I saw many other bugs also related to ssh timeout. There are many other tests doing ssh, all those are passing? And does this tests fail consistently ? (As this tests is not failing on gate)
I will suggest to log this as qa bug and provide more log information if possible - https://bugs.launchpad.net/tempest

>SSHTimeout: Connection to the 10.20.14.210 via SSH timed out.

Thanks
gmann

Subject: [openstack-dev] "tempest.lib.common.ssh AuthenticationException: Authentication failed." error when run“tempest.api.compute.servers.test_create_server.ServersTestJSON.test_host_name_is_same_as_server_name”

Hello~ Anyone would concern:
We are running the API tests on our cloud with the refstack-client tool. We have prepared the prerequisites required by the official guide.
However, the results reported the “tempest.lib.common.ssh AuthenticationException: Authentication failed.” error and the test for “tempest.api.compute.servers.test_create_server.ServersTestJSON.test_host_name_is_same_as_server_name” Failed.
We have googled this problem but no useful solutions are found. Would anyone pay attention on our problem and give some advices to solve the error ?
My openstack is Icehouse version,
#nova-manage version
2014.1.3
The official refstack-client guide we refer to is https://github.com/openstack/refstack-client.
More details related to the error are followings:
1、Execute compute cases
# ./refstack-client test -c ~/refstack-client/.tempest/etc/tempest.conf -v -- tempest.api.compute.servers.test_create_server.ServersTestJSON.test_host_name_is_same_as_server_name
2、The test output
==============================
Failed 1 tests - output below:
