Re: [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?
