The problem is the kernel version. It is old

[vagrant@oracle-70-x64 ~]$ uname -a
Linux oracle-70-x64.vagrantup.com 3.8.13-35.3.1.el7uek.x86_64 #2 SMP Wed Jun 25 15:27:43 PDT 2014 x86_64 x86_64 x86_64 GNU/Linux

Compared to for example Ubuntu

$ uname -a
Linux kore 3.13.0-24-generic #46-Ubuntu SMP Thu Apr 10 19:11:08 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
