+ ## Deploying DPDK requires enabling hugepages for the overcloud compute nodes.
+ ## It also requires enabling IOMMU when using the VFIO (vfio-pci) OvsDpdkDriverType.
+ ## This can be done using ComputeKernelArgs as shown below.
+ #ComputeParameters:
+ #ComputeKernelArgs: "intel_iommu=on default_hugepagesz=2MB hugepagesz=2MB hugepages=2048"
+ ## Attempting to deploy DPDK without appropriate values for the below parameters may lead to unstable deployments
+ ## due to CPU contention of DPDK PMD threads.
+ ## It is highly recommended to to enable isolcpus (via ComputeKernelArgs) on compute overcloud nodes and set the following parameters:
+ #OvsDpdkSocketMemory: "" # Sets the amount of hugepage memory to assign per NUMA node.
+ # It is recommended to use the socket closest to the PCIe slot used for the
+ # desired DPDK NIC. Format should be comma separated per socket string such as:
+ # "<socket 0 mem MB>,<socket 1 mem MB>", for example: "1024,0".
+ #OvsDpdkDriverType: "vfio-pci" # Ensure the Overcloud NIC to be used for DPDK supports this UIO/PMD driver.
+ #OvsPmdCoreList: "" # List or range of CPU cores for PMD threads to be pinned to. Note, NIC
+ # location to cores on socket, number of hyper-threaded logical cores, and
+ # desired number of PMD threads can all play a role in configuring this setting.
+ # These cores should be on the same socket where OvsDpdkSocketMemory is assigned.
+ # If using hyperthreading then specify both logical cores that would equal the
+ # physical core. Also, specifying more than one core will trigger multiple PMD
+ # threads to be spawned, which may improve dataplane performance.
+ #NovaVcpuPinSet: "" # Cores to pin Nova instances to. For maximum performance, select cores
