  • How to map vCpu to pCpu using NUMA in hyper-threaded system ?
    • For ex:
cpu0: 0 1 2 3 8 9 10 11.
Here if we were to assume that 0,1,2,3 are the physical cores and 8,9,10,11 are the siblings. If I wanted to have 4 CPUs pinned, I would want them as follows:

vcpu0 = lcore0
vcpu1 = lcore1
vcpu2 = lcore2
vcpu3 = lcore3
  • Is it possible ?
