[Bug 2100343] [NEW] Unable to overcommit CPU
Public bug reported:
Cannot overcommit CPU - cpu_allocation_ratio in nova.conf is ignored.
I am using Dalmatian release on Ubuntu 24.04
Steps to reproduce:
1. cpu_allocation_ratio = 16 in /etc/nova/nova.conf
2. restart nova-schedular and nova-compute
3. try provision vm so that the total vcpu count exceeds the physical cpu count in host.
Following is from nova-conductor.log
