I found the root cause in my environment.
I use libvirt in LXC. And the lxc doesn't enable the cgroup w/ read and write permission. I add/change the config file with following line.
lxc.aa_profile = lxc-container-default-with-nesting
And install `cgroup-lite` in lxc guest. The libvirt works with CPU affinity.
