Use a vhostuser VIF with only tx_queue_size set. Actual results: vhost_tx_queue_size not set when rx_queue_size is not provided.

According to our records, this should be resolved by openstack-nova-16.0.4-15.el7ost. This build is available now.
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. #rx_queue_size=<None> # Configure virtio tx queue size. #tx_queue_size=<None> tx_queue_size=1024 ... 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'/> </interface>
