only_pcpu

Overview​

Specify CPU core isolation

Command Parameters​

-c|--cpustr=string            Required parameter, CPUs to isolate: '1,2,3,7-9', parameter is valid when isolating VM or specifying cores

Usage Example​

# Example 1: Isolate specified CPU cores
acli performance_tools isolate only_pcpu -c 0

Output Example​

Will migrate vn management plane processes 
Will migrate root directory processes 
Will use mgmt api for isolation
