Has openstack any limitations about number of cpu with dpdk?

I have a server which has got 32 cores.I can use 24 cores but ı couldnt use 8 core with numatopology. How can I resolve this. this is my nova cpu pin set config vcpu_pin_set=22,24,25,26,27,28,29,30,31,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63 ovs side config: 17,18,19,20,21,23,27 cpu cores dedicated 17,19,21,23 pmd and lcore settings nova tail output: total_vcpus=25 used_vcpus=13 pci_stats=[]

yes ı can create vm with 11 cores but ı couldnt create 12 cores.

Why?

I tried siblings set in ovs.İt couldnt work.
