Hi, I'm trying to set different values for NovaVcpuPinSet for different type of compute nodes I have in my cluster. I have custom role "Computesriov" defined as shown below and I set the NovaVcpuPinset as following in the network-environment.yaml file parameter_defaults: ... NovaVcpuPinSet: ['2-23','26-47'] ComputesriovParameters: NovaVcpuPinSet: ['2-23'] After deployment I checked /etc/nova/nova.conf and vcpu_pin_set = "2-23,26-47" Any idea why it's setting the specific value?
