为用户创建cgroup的步骤：
sudo service cgmanager start
sudo cgm create all $USER
sudo cgm chown all $USER $(id -u $USER) $(id -g $USER)
cgm movepid all $USER $PPID
尝试启动容器：
lxc-start -n hola -P /home/edem/.local/share/lxc/ --logfile asdf --logpriority DEBUG
lxc-start: Permission denied - Could not create cgroup '/hola' in '/sys/fs/cgroup/perf_event'.
