Doc Text:	There is a known issue wherein deployments will fail with the following message. `puppet-user: Error: Parameter value failed on Vs_config[other_config:n-revalidator-threads]: Invalid external_ids 1. Requires a String, not a Integer` This is due to tripleo parameters of type integer being expected by puppet to be of type string. To work around, include the following in deployment templates: ComputeOvsDpdkSriovExtraConfig: "vswitch::dpdk::handler_cores": "1" "vswitch::dpdk::revalidator_cores": "1"	Story Points:	---

Description Vadim Khitrin 2019-07-17 11:16:34 UTC

Description of problem:
Two additional OVS parameters were introduced in OSP15: ‘OvsRevalidatorCores’ and ‘OvsHandlerCores’.

These TripleO parameters are of ‘number’ type and are set by default to 1 (defined in  /usr/share/openstack-tripleo-heat-templates/puppet/services/openvswitch.yaml).

Puppet vswitch module expects the hieradata generated by TripleO params to be of type ‘string’.

The following error will be raised as part of openstack overcloud failures:
"<13>Jul 17 09:38:50 puppet-user: Error: Parameter value failed on Vs_config[other_config:n-revalidator-threads]: Invalid external_ids 1. Requires a String, not a Integer (file: /etc/puppet/modules/vswitch/manifests/dpdk.pp, line: 120)",


Version-Release number of selected component (if applicable):
Compose: RHOS_TRUNK-15.0-RHEL-8-20190714.n.0
rpm -qa | grep tripleo-heat
openstack-tripleo-heat-templates-10.6.1-0.20190713150434.2871ce0.el8ost.noarch

Actual results:
Deployment fails

Expected results:
Deployment passes

Comment 1 Vadim Khitrin 2019-07-17 15:09:54 UTC

Workaround for now is to include ExtraConfig, for example my Compute role is ‘ComputeOvsDpdkSriov’, I added the following parameter to deployment templates:
ComputeOvsDpdkSriovExtraConfig:
  "vswitch::dpdk::handler_cores": "1"
  "vswitch::dpdk::revalidator_cores": "1"

Vadim can you update the status and maybe see if this can be closed.
