Description James Parker 2020-04-29 15:13:35 UTC 
Description of problem:
Based on the tuning recommendations for compute realtime workloads [1] from Kernel-RT, irqbalance should be stopped and disabled.  tuned will be responsible for managing IRQ balancing instead of irqbalance.  Currently in RT deployments both services will be active simultaneously.

Version-Release number of selected component (if applicable):


How reproducible:
100% when deploying a compute Real Time deployment

Steps to Reproduce:
1. Deploy a Compute Real Time Role in RHOS  
2.
3.

Actual results:
irqbalance service is active and running alongside tuned

Expected results:
irqbalance service is stopped and disabled
