      Document "Configuring the Compute service for instance creation", RHOSP 17.1, chapter 8, section 8.2, step 8  [0] includes the following snippet:

      parameter_defaults:
  ...
  ComputePCIParameters:
    KernelArgs: "intel_iommu=on iommu=pt \ vfio-pci.ids=<pci_device_id> rd.driver.pre=vfio-pci"

      The trailing backslash and additional space between `iommu=pt` and `vfio....` is unnecessary.

      In contrast, similar configuraion in RHOSO 18.0 guide (9.4 step 10) [1] does not show the same:

      apiVersion: dataplane.openstack.org/v1beta1
kind: OpenStackDataPlaneNodeSet
metadata:
    name: my-data-plane-node-set
spec:
    …
    nodeTemplate:
        …
        ansible:
            ansibleVars:
edpm_kernel_args: "default_hugepagesz=1GB hugepagesz=1G hugepages=64 intel_iommu=on iommu=pt tsx=off isolcpus=2-11,14-23 vfio-pci.ids=10de:1eb8 rd.driver.pre=vfio-pci"
