cant start docker after installation on linux

Question

hy On my CentOS Linux release 6.0 with kernel version 3.15.7-1.el6.elrepo.x86_64, i've installed docker like that

yum install docker-io  it's ok 

but when i try to start docker i get this

 /etc/init.d/docker start  
Starting docker:                                           [  OK  ]

in the log file i see this

[5b73ca03] +job serveapi(unix:///var/run/docker.sock)
[5b73ca03] +job initserver()
[5b73ca03.initserver()] Creating server
2014/07/30 13:52:24 Listening for HTTP on unix (/var/run/docker.sock)
exit status 1
[5b73ca03] -job initserver() = ERR (1)
2014/07/30 13:52:25 exit status 1

i really dont understand why i get -job initserver() = ERR (1) i read a lot of tutorial for install docker on centos, i also try to add in fstab " none /sys/fs/cgroup cgroup defaults 0 0 " when i try grep aufs /proc/filesystems i see nothing that normal ?

i get this reponse from unclejack on github
That setup is unsupported. Please upgrade to RHEL7 if you want to use a newer kernel than what CentOS 6 ships.
