Open Stack

Hi Guys,

Now I found the solution for my problem:

n-api installation/start (via devstack) failed on centos 6.x with the error
message below

================

The problem is the old python-paste version of centos.

So if you get this error, just remove python-paste with:

yum remove python-paste python-paste-deploy python-paste-script

and install the new one via pip:

pip install --upgrade paste PasteDeploy PasteScript

in the last step you have to remove the package names (paste, paste-deploy,
paste-script) in devstack (./files/rpms/*) , because stack.sh will install
this package with the next run.

=================
