How do i remove cpus from one cpupool & add them to another cpupool?



  • We want to balance out the cpus in a cpupools, can see uat pool has not cpus and we want to add cpu's 2 & 3 to that pool.

    # xl cpupool-list
    Name               CPUs   Sched     Active   Domain count
    Pool-0               4    credit       y          2
    uat                  0   credit2       y          0
    
    xenhorse:/xen/data# xl cpupool-list -c
    Name               CPU list
    Pool-0             0,1,2,3
    uat 
    

    Remove the cpus from Pool-0 first

    # xl cpupool-cpu-remove Pool-0 3
    # xl cpupool-cpu-remove Pool-0 2
    # xl cpupool-list -c
    Name               CPU list
    Pool-0             0,1
    uat                
    

    Add the removed cpus to the uat pool.

    # xl cpupool-cpu-add uat 2
    # xl cpupool-cpu-add uat 3
    # xl cpupool-list -c
    Name               CPU list
    Pool-0             0,1
    uat                2,3
