Dear Anton Beloglazor,
The first, Thanks to you, Anton
I want using Openstack-Neat to automation migrate (or arrange ) instances in compute servers..
I read your books/slides (thesis, openstack-neat-blueprint,..) and I decided to install Openstack-Neat on my lab
I did the following steps:
On Controller node: (using Ubuntu 12.4-LTS):
+ git clone git://github.com/beloglazov/openstack-neat.git
+ sudo python setup.py install
+ edit the neat.conf file (fill the compute nodes,...)
+ ./compute-clone-deps.py
+ ./compute-install-neat.py
+ ./compute-copy-conf.py
and: ./all-start.sh
/etc/init.d/openstack-neat-data-collector: 24: .: Can't open /etc/rc.d/init.d/functions+ sudo python setup.py install
+ edit the neat.conf file (fill the compute nodes,...)
+ ./compute-clone-deps.py
+ ./compute-install-neat.py
+ ./compute-copy-conf.py
and: ./all-start.sh
/etc/init.d/openstack-neat-db-cleaner: 22: .: Can't open /etc/rc.d/init.d/functions
I checked openstack-neat-data-collector file on Compute node, and see they be only run on redhat environment (/etc/rc.d/init.d/functions, /etc/sysconfig/,,/) but not for Ubuntu.
More important is bin files don't exist ( /usr/bin/neat-* ).
Please guide me!
Thank you so much!

Hi Ta Ba Tuan,
Thanks for your interest in the project! Unfortunately, I haven't had a chance to test it on Ubuntu (it's been tested on Centos). Since the all-start.sh script uses Centos interface, it won't work on Ubuntu. However, Python's distribute module should correctly handle various Linux distributions; therefore, neat-* executables should still be installed somewhere when you run `sudo python setup.py install`. Can you please try to search for neat-* files? They might be in /bin or wherever they get installed in Ubuntu by default. If you can't find them, you can use the start-data-collector.py, start-global-manager.py, and start-local-manager.py scripts in the project's root to start up the services. Please let me know how it goes.
Best regards,
Anton

Hi Anton and everyone,
My environment use the SSL for every connections,
When the Global_manager receied requests from compute nodes AND Global_manager prcocess these requests, appear the following error:

Ofcource, I configured neat.conf file with "os_auth_url = https://controller:5000/v2.0/"
How to use Openstack-Neat when using them in SSL environment.
Thank you!

Hi Ta Ba Tuan,
Do you still have that problem? The log of the local manager shows that the request has failed on the global manager. The global managers fails due to the SSL issue you wrote about in the previous email. Is it possible to test it without SSL in your environment?
Best regards,
Anton
