[libvirt-users] why CPU pinning doesn't take effect when using lxc-enter-namespace to run an application

Dear all, I want my container to run on the third CPU core and I define this by the following xml scrpits: <vcpu placement="static" cpuset="3">1</vcpu> When I run my application in a container terminal, I can see the application runs on the third core as expected. When I run my application using lxc-enter-namespace, the CPU pinning doesn't take effect, i.e., the application runs on a core which isn't the third one. How can I solve this problem? Any replies are highly appreciated. Cheng
