Hi All, I am new to openstack. I have a problem in understanding of Nova-database update with the resources information. My understanding after going through the architecture documents and code is Nova-Database is the one which stores the resource information about the compute servers. The Nova-Scheduler is responsible to place a VM on a correct compute node where the resources are available. Nova-compute is responsible for creating the VMs/Containers etc. The question here is who actually updates the in real time the resource information in the Nova-Database by reading the resources information from the compute servers/nodes? I have read about agents are responsible for this, but I dint get which code does that. Can any one please help me in clarifying my doubt and please guide me for the code which does that. Thanks in advance Cheers, Pradeep __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: [email protected]?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
Mostly nova-conductor but sometimes also nova-api. Pretty much anything that imports nova.db.api.
