root>echo "lxcuser veth lxcbr0 2" | tee -a /etc/lxc/lxc-usernet
lxcuser>mkdir -p ~/.config/lxc
lxcuser>echo "lxc.id_map = u 0 100000 65536" > ~/.config/lxc/default.conf
lxcuser>echo "lxc.id_map = g 0 100000 65536" >> ~/.config/lxc/default.conf

lxc_container: command get_cgroup failed to receive response
