kernel version

Docker node OS and kernel version：

[root@docker docker]# cat /etc/redhat-release 
CentOS Linux release 7.1.1503 (Core) 
[root@docker docker]# uname -a 
Linux docker 3.10.0-229.el7.x86_64 #1 SMP Fri Mar 6 11:36:42 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
[root@docker docker]# 

Docker OS and version：

[root@lala /]# cat /etc/redhat-release 
CentOS release 6.6 (Final)
[root@lala /]# uname -a 
Linux lala 3.10.0-229.el7.x86_64 #1 SMP Fri Mar 6 11:36:42 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
[root@lala /]#

不知道有什麼方法可以讓各自的OS對應自己的kernel version ，而非都是docker node 的kernel version?
