Hi Guys,
I started a lxc container with libvit in ubuntu Operating system, and succeed using lxc-enter-namespace to enter the namespaces and security context of the container. But when I do the same thing in debian OS, It reported an error, with details as following:

root@debian:/etc# vir lxc-enter-namespace 4424 /bin/sh/
libvirt: error : argument unsupported: Security model cannot be entered
Is there anything that needs to be configured in debian OS for using the 'lxc-enter-namespace' interface?
