Title:
Set cpu_allocation_ratio by placement cli , lead to compute_nodes
table keep old cpu_allocation_ratio
Status in OpenStack Compute (nova):
Expired
Bug description:
Hello, I encountered some problems when using the cpu_allocation_ratio
and I hope to get help from the community.
old nova.conf
cpu_allocation_ratio=10.0
new nova.conf:
cpu_allocation_ratio=None
initial_cpu_allocation_ratio=4.0
Restart compute service, and execute placement cli:
openstack resource provider inventory set
959339b3-6d23-4780-8052-a51067c00659 --resource VCPU:allocation_ratio=5 --amend

NUMATopologyFilter will use compute.cpu_allocation_ratio to
host_passes numa vm, not inventory VCPU allocation_ratio. This will
result in scheduling errors.
