Description of problem:
unable to deploy compute node with sriov agent only (no ovs agent)

Version-Release number of selected component (if applicable):


How reproducible:
deploy overcloud with OS::TripleO::Services::ComputeNeutronOvsAgent: OS::Heat::None (like with opendaylight for example)

Steps to Reproduce:
1.
2.
3.

Actual results:
the sriov agent will failed to load

Expected results:


Additional info:
this is because of missing include in the sriov.pp

the code is:
class tripleo::profile::base::neutron::sriov(
  $step               = hiera('step'),
  $mechanism_drivers  = hiera('neutron::plugins::ml2::mechanism_drivers'),
) {

  if $step >= 4 {
    if 'sriovnicswitch' in $mechanism_drivers  {
      include ::neutron::agents::ml2::sriov
      include ::tripleo::host::sriov
    }
  }

}

which not including "::tripleo::profile::base::neutron" that responsible to configure neutron.conf which holds all the rabbit conf

to fix just modify to:
class tripleo::profile::base::neutron::sriov(
  $step               = hiera('step'),
  $mechanism_drivers  = hiera('neutron::plugins::ml2::mechanism_drivers'),
) {

  include ::tripleo::profile::base::neutron

  if $step >= 4 {
    if 'sriovnicswitch' in $mechanism_drivers  {
      include ::neutron::agents::ml2::sriov
      include ::tripleo::host::sriov
    }
  }
}
