Hi,
I found that it turned out that VM instance could not allocate IP.
Here is some points from here:
1) I tried to use all in one configurations by devstack, and i had only
one interface with default setting.

2) Also tried following conf as Doc said:
[[local|localrc]]
## Neutron options

SERVICE_HOST=10.128.10.70
MYSQL_HOST=10.128.10.70
RABBIT_HOST=10.128.10.70
GLANCE_HOSTPORT=10.128.10.70
# Do not use Nova-Network
disable_service n-net
# Enable Neutron
ENABLED_SERVICES+=,q-svc,q-dhcp,q-meta,q-agt,q-l3
# Neutron options
Q_USE_SECGROUP=True
FLOATING_RANGE="10.128.10.0/24"
IPV4_ADDRS_SAFE_TO_USE="10.0.0.0/22"
Q_FLOATING_ALLOCATION_POOL=start=10.128.10.59,end=10.128.10.60
PUBLIC_NETWORK_GATEWAY="10.128.9.254"
PUBLIC_INTERFACE=em1
Either way, VM instances could not allocate IP, any Ideas?
Thanks,
Shilong

Hi Wang,
Do you see the created machine in the cloud provider?
Can you ping it?
Can you ssh it 'manually'
We had some issues with key's that showed a similar 'ssh' error.
There are also some errors that are not caught/displayed in the logs,
So, sometimes you need to run things manually to get a deeper understanding of the problem

Hi Wang,
The ip should be correct. It's possible that the ip in the log message is slightly different because it refers to a different instance floating ip?
If you have a nodepool image uploaded already, I suggest you try to manually launch a node using that image outside of nodepool. You should be able to ssh into it as Ubuntu user using the ssh private key provided when you created the image.

Hello Guys,
I am following https://github.com/openstack-infra/puppet-openstackci/blob/master/doc/source/third_party_ci.rst
to setup CI.
I hit following problem from nodepool log.
2017-02-08 22:59:35,529 ERROR nodepool.utils: Exception while testing ssh access to 172.24.4.2:
Traceback (most recent call last):

2017-02-08 22:59:37,533 ERROR nodepool.NodeLauncher: Timeout launching node id: 4311 in provider: local_01 error: Timeout waiting for ssh access
After some checking, problem is openstack VM instance ip is not what openstack specified, for example for above case, indeed allocation ip of VM is 172.24.4.5.
So nodepool always failed because of this reasons, how can i slove this mismatch problems and proceed CI testing?
Thank you!
Shilong

Hello folks,
We are trying to setting up CI testing system for new Lustre cinder Drivers.
I try to do as following URL In centos7:
http://www.joinfu.com/2014/02/setting-up-an-external-openstack-testing-system/
But hit the following problem:
[root at vm7-1 ~]# ./install_master.sh
Using upstream Gerrit user: ddn_openstack Using Jenkins SSH key path: /root/data/jenkins_key

Error: Could not find template 'openstack_project/puppet.conf.erb' at /root/os-ext-testing/puppet/modules/os_ext_testing/manifests/base.pp:132 on node vm7-1
I guess this Doc might be out of date, could you please give me some hints how I can setup latest CI?
Thanks for your suggestion!
Shilong
