Bug Description
Currently ServerGroupAffi
Example:
max_instances_
quota_server_
When user_1 would spawns 3 instances with affinity server group policy, all the instances will be scheduled on the same host (host_A).
If user_2 also spawns instances and they are placed on host_A, quota of max_instances_
My proposition is to add new parameters to nova.conf to configure ServerGroupAffi
- enable_
- reserved_
Nova scheduler checks if on a host there are any instances with affinity policy and based on that, it counts available slots.
Nova doesn't have (yet) in its scope to manage instance allocations and that really looks like a new feature that should be discussed in a spec.
