commit 5160d4e2ae285c62ab52c9dfc61121f8ca4ecd57 Author: Hong Hui Xiao <[email protected]> Date: Fri Dec 4 00:19:00 2015 -0500 Make sure AZAwareWeightScheduler base on weight of agent Problem details can be found in bug description. AZ here stands available zone. heapq.heapify() will sort tuple according to the first element. If the first element is equal, then the second element is used. When creating a new network, each AZ doesn't hold the network. So, the AZ handling list is actually a name ordered list. As a consequence, when creating a new network, a certain AZ will always be used, for example, 'nova1' in ['nova1', 'nova2', 'nova3']. This patch will sort the resource_hostable_agents firstly, so that the AZ that holds dhcp-agent with least load comes first. Then use min() to get the first AZ.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1522677 Title: AZAwareWeightScheduler is not totally based on weight Status in neutron: Fix Released Bug description: The AZ(available zone) for network has been enable with the merging of [1]. I try in local devstack with latest code. 1) I deploy 3 dhcp-agent in 3 AZs (nova1, nova2, nova3). 2) set the dhcp_agent_per_network=1, don't set default_availability_zones, and set network_scheduler_driver = neutron.scheduler.dhcp_agent_scheduler.AZAwareWeightScheduler 3) create 10 networks without specifying the availability_zone_hints 10 networks all go to nova1. It is not a reasonable result.
