Doc Type: Technology Preview
Doc Text:
With this technology preview update, you can set the following parameters to configure OVS PMD auto load balance: * `OvsPmdAutoLb` Enable/disable the OVS DPDK PMD Auto Load Balance feature. Values: true or false. OVS DPDK uses the default value of false. * `OvsPmdLoadThreshold` Set the minimum PMD thread load threshold for OVS DPDK PMD Auto Load Balance feature. Set a value from 0 to 100 to specify the minimum PMD thread load threshold (percentage of used cycles) of any non-isolated PMD threads when a PMD Auto Load Balance might be triggered. * `OvsPmdImprovementThreshold` Set PMD load variance improvement threshold for OVS DPDK PMD Auto Load Balance feature. Set a value from 0 to 100 to specify the minimum evaluated percentage improvement in load distribution across the non-isolated PMD threads that allows a PMD Auto Load Balance to occur. * `OvsPmdRebalInterval` Set PMD auto load balancing interval for OVS DPDK PMD Auto Load Balance feature. Set a value from 0 to 20,000 to specify the minimum time (in minutes) between 2 consecutive PMD Auto Load Balancing iterations.

Description yogananth subramanian 2021-04-21 12:50:18 UTC 
Description of problem:
At present it is not possible set OVS auto balance parameters though TripleO
By setting OVS auto balance parameters pmd-auto-lb-load-threshold,pmd-auto-lb-improvement-threshold,pmd-auto-lb-rebal-interval,pmd-auto-lb
through TripleO, the end user easily customize them during deployment according to their requirement

These parameter would enable the end user to set load threshold(pmd-auto-lb-load-threshold), variance improvement threshold(pmd-auto-lb-improvement-threshold), minimum time between 2 consecutive PMD auto load balancing iterations(pmd-auto-lb-rebal-interval)
