According to our records, this should be resolved by openstack-nova-16.0.4-15.el7ost.  This build is available now.

Comment 4 Joe H. Rahme 2018-07-30 17:23:49 UTC
Verified that setting the tx_queue_size config value without setting an rx_queue_size value...

[heat-admin@computeovsdpdk-0 ~]$ sudo docker exec -i nova_libvirt grep '[rt]x' /etc/nova/nova.conf
# Configure virtio rx queue size.
# Configure virtio tx queue size.

... does yield the proper values in the libvirt xml:

    <interface type='vhostuser'>
      <mac address='fa:16:3e:90:6f:bb'/>
      <source type='unix' path='/var/lib/vhost_sockets/vhud27af13f-6e' mode='server'/>
      <target dev='vhud27af13f-6e'/>
      <model type='virtio'/>
      <driver tx_queue_size='1024'/>
      <alias name='net0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/>
