- **Default**: ``false``
- **Examples**: ``true``
- ``tripleo_ovs_dpdk_pmd_load_threshold``
- **Description**: (*Optional*) Minimum PMD thread load threshold, in range
0 to 100. Its a string with a number, specifies the minimum
PMD thread load threshold (% of used cycles) of any non-isolated PMD threads
when a PMD Auto Load Balance may be triggered.
- **Default**: ``''``
- **Examples**: ``'50'``
- ``tripleo_ovs_dpdk_pmd_improvement_threshold``
- **Description**: (*Optional*) PMD load variance improvement threshold, in range
0 to 100. Its a string with a number, specifies the minimum evaluated % improvement
in load distribution across the non-isolated PMD threads that will allow
a PMD Auto Load Balance to occur.
Note, setting this parameter to 0 will always allow an auto load balance to occur
regardless of estimated improvement or not.
- **Default**: ``''``
- **Examples**: ``'10'``
- ``tripleo_ovs_dpdk_pmd_rebal_interval``
- **Description**: (*Optional*) PMD auto load balancing interval, in range
0 to 20,000. Its a string with a number, specifies the minimum time (in minutes)
between 2 consecutive PMD Auto Load Balancing iterations. The defaul value is 1 min.
- **Default**: ``''``
- **Examples**: ``'5'``
