Hi Kashyap,
Thanks a lot for your reply. I do see the fix in my environment.
In /usr/lib/python2.7/site-packages/neutron/common/config.py, I see the
following code snippet at line numbers 89 and 90.
89 cfg.StrOpt('nova_url',
90 default='http://127.0.0.1:8774/v2',
In /etc/neutron/neutron.conf, I do have the Nova v2 API version number in
the URL below. But, instead of 127.0.0.1, I have the IP address of the network
host which is same as CONFIG_NETWORK_HOSTS in my packstack-answers.txt.
# URL for connection to nova (Only supports one nova region currently).
nova_url = http://172.29.68.136:8774/v2
I have the below line in my packstack-answers.txt.
CONFIG_NETWORK_HOSTS=172.29.68.136
Yes, I can reproduce this issue every single time. Am I seeing a new bug ?
Please let me know if there is any work-around, and also if I need to send any
logs/debugs.

Hi,
I have been hitting the RDO bug
https://bugzilla.redhat.com/show_bug.cgi?id=1087589, and not able to
boot a nova instance.
As you might have noticed, that bug is fixed upstream more than 6 months
ago, so it's reasonable to expect to have it in current RDO stable
versions for sure (Juno).
I see that the fix https://review.openstack.org/#/c/92387/ was merged
on May 29th 2014. Is this fix available in the latest RDO ?
I checked the source of python-neutron RPM for for both CentOS (from
latest RDO) and your package version -- the above fix is available in
both.
- python-neutron-2014.2.1-1.el7.centos.noarch.rpm (From here
https://repos.fedorapeople.org/repos/openstack/openstack-juno/epel-7/)
- python-neutron-2014.1.2-2.el7ost.noarch.rpm
Below are the package versions of neutron and nova in my RHEL 7
IceHouse setup. How can I check if the fix is available in my packages
below ?
That fix is part of this file:
usr/lib/python2.7/site-packages/neutron/common/config.py
You can try two things:
- In this file
/usr/lib/python2.7/site-packages/neutron/common/config.py, you can
check if you have the relevant code snippet:
. . .
cfg.StrOpt('nova_url',
default='http://127.0.0.1:8774/v2',
. . .
- In your /etc/neutron.conf, ensure the 'nova_url' config parameter
has the Nova v2 API version number in the URL:
nova_url = http://127.0.0.1:8774/v2
[. . .]
Below are the errors of the above bug I see when I boot an instance. Please let me know
the solution/work-around. Thanks a lot!
