I'm trying to intall devstack but the script always fails at the same point when calling the command glance image-create. I receive a HTTP500 Internal Server Error. Here are the last few lines of the output of

This are the last few lines of screen-g-api.log:

I thought if mysql has something to do with it? I already increased the allocatable resources (buffer,cache) for mysql (/etc/mysql/my.cnf). Because I want to work with ironic due to localrc nova-network is disabled and neutron is enabled.

I already successfully set up devstack a few weeks ago, but since I installed my VM again I can't bring it up again.

I am a newbie to openstack. I am trying to install Openstack using devstack in my virtualbox (Ubuntu 12.04 32 bit). I ran ./ and get an httpinternalservererror. Please find the logs for reference here

I just ran ./ and ended up in that error. I think this is an issue with glance. However, I do not know much about openstack, so i am unable to give more details. I have pasted the logs. Any help would be appreciated.

Also, is there any way to incorporate DRS with nova so that we can do load balancing on the go without using ESX

Thank You very much for your response Bill. We will now research in the direction you have mentioned. Are there any particular resources I could refer to so that I get an elaborate idea about the same. Will it be a good idea to start with the Nova Schedular?

2014-02-11 05:21:19 -0500 asked a question Balancing CPU Load in Openstack

Hello, I am a newbie to OpenStack. We are trying to work on implementing some CPU Load Balancing Algorithms in OpenStack. I am aware that Neutron in OpenStack Havana supports LBaaS (Load Balancing as a Service). But this kind of a load balancing relates to the load balancing of network aspects. We are interested in balancing the computational load on the servers in the cloud using Load Balancing. Essentially we would like to implement algorithms like Ant Colony Optimization, Active Clustering etc., in Openstack. But these algorithms should balance only the computational load so that at any given instant of time no server is overloaded or underloaded with jobs. I would like to know how we should go about implementing these algorithms and in which modules/components these algorithms must be implemented. Is there a possibility to implement these algorithms in Nova -Compute component?

Any help would be appreciated. Thank You.
