sorry for late reply
we have reinstall the OVS, but still having the same issue.
we tried to set the pmd-cpu-mask=3, but only CPU1 is occupied.
%Cpu0 :100.0 us, 0.0 sy, 0.0 ni, 0.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st
%Cpu1 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st
%Cpu2 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st
%Cpu3 : 0.0 us, 0.0 sy, 0.0 ni,100.0 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st
# /usr/local/bin/ovs-vsctl get Open_vSwitch . other_config
{dpdk-init="true", pmd-cpu-mask="3"}
# /usr/local/bin/ovs-appctl dpif-netdev/pmd-rxq-show
pmd thread numa_id 0 core_id 0:
isolated : false
port: dpdk0 queue-id: 0
pmd thread numa_id 0 core_id 1:
isolated : false
is it because there is only one nodes available in numa?
# numactl -H
available: 1 nodes (0)
node 0 cpus: 0 1 2 3
node 0 size: 8191 MB
node 0 free: 2633 MB
