Doc Text:	Previously, users could set RX/TX queue size with `nova::compute::libvirt::rx_queue_size/nova::compute::libvirt::tx_queue_size`. However, there was no dedicated TripleO heat template parameter. With this update, users can set the RX/TX queue size on a role base: ``` parameter_defaults: ComputeParameters: NovaLibvirtRxQueueSize: 1024 NovaLibvirtTxQueueSize: 1024 ```	Story Points:	---

+++ This bug was initially created as a clone of Bug #1617927 +++

Description of problem:
RX/TX Queue size implemented in RHOSP 14 according to the following BZ [1] [2], missing THT parameters.

[1] - https://bugzilla.redhat.com/show_bug.cgi?id=1553088
[2] - https://bugzilla.redhat.com/show_bug.cgi?id=1512941

THT parameters should configure rx_queue_size and tx_queue_size in nova.conf
[libvirt]
rx_queue_size=1024
tx_queue_size=1024

--- Additional comment from Eric Elena on 2018-08-16 04:18:31 EDT ---

Please note that as per [0] you can use the following snippet:

parameter_defaults:
  ComputeExtraConfig:
    nova::compute::libvirt::rx_queue_size: 1024
    nova::compute::libvirt::tx_queue_size: 1024

--- Additional comment from Martin Schuppert on 2018-08-22 05:58:49 EDT ---

RX/TX queue size can be set on a role base like:

parameter_defaults:
  ComputeParameters:
    NovaLibvirtRxQueueSize: 1024
    NovaLibvirtTxQueueSize: 1024

[root@compute-0 ~]# egrep "^rx|^tx" /var/lib/config-data/puppet-generated/nova_libvirt/etc/nova/nova.conf 
rx_queue_size=1024
tx_queue_size=1024

Comment 6 Joe H. Rahme 2018-11-26 07:07:18 UTC

Verified by running the following paramters:

parameter_defaults:
  ComputeExtraConfig:
    nova::compute::libvirt::rx_queue_size: 1024
    nova::compute::libvirt::tx_queue_size: 1024
