[libvirt-users] Question about setns recognising in libvirt autoconf



Hi experts,
 
When I test lxc container with lxc-enter-namespace command, It reported an error as
following:
root debian:~/github/libvirt# vir lxc-enter-namespace lxc --noseclabel /bin/df -hl
error: Cannot get namespaces for 3145: Function not implemented
 
It seems that setns is not supported by my kernel.
 
But from the following info, It seemed the reason is just libvirt/autoconf doesn't
recgonise setns.
root debian:~/github/libvirt# grep setns /proc/kallsyms
ffffffff8105b78b T SyS_setns
ffffffff8105b78b T sys_setns
root debian:~/github/libvirt# ./configure | grep setns
checking for setns... no
 
What the problem really is ? How can I fix this problem?
Thanks~
