Hi,

I've deployed an overcloud with RHOSP11 with multiple roles for compute nodes with ovs-dpdk.

I used a different role for each group of compute nodes that have a different amount cores.

Therefor I set the following parameters to set the cores configuration accordingly

NeutronDpdkCoreList: "100"

HostCpusList: "100"

ComputeV4NeutronDpdkCoreList: "22,46,23,47"

ComputeV4HostCpusList: "0,24"

ComputeV4ExtraConfig:

nova::compute::vcpu_pin_set: ['1-21','25-45']

vswitch::dpdk::pmd_core_list: "22,46,23,47"

vswitch::dpdk::host_core_list: "0,24"

ComputeV4KernelArgs: "default_hugepagesz=1GB hugepagesz=1G hugepages=124 intel_iommu=on iommu=pt"

ComputeV4HostIsolatedCoreList: '1-23,25-47'

ComputeV4NeutronDpdkCoreList: "22,46,23,47"

ComputeV4HostCpusList: "0,16"

ComputeV3ExtraConfig:

nova::compute::vcpu_pin_set: ['1-13','17-29']

vswitch::dpdk::pmd_core_list: "14,15,30,31"

vswitch::dpdk::host_core_list: "0,16"

ComputeV3KernelArgs: "default_hugepagesz=1GB hugepagesz=1G hugepages=124 intel_iommu=on iommu=pt"

ComputeV3HostIsolatedCoreList: '1-15,17-31'

NeutronDpdkCoreList and HostCpusList have dummy values that are overwritten by "vswitch::dpdk::pmd_core_list" and "vswitch::dpdk::host_core_list" under [ROLE]ExtraConfig part

The [ROLE]NeutronDpdkCoreList, [ROLE]HostCpusList, [ROLE]HostIsolatedCoreList are used in the first_boot.yaml

It works but wondering if there is a better way to do that??
