Hi, when installing OpenVZ kernel (yum install vzkernel) at plain CentOS 6.4 from OVH, it said:

"grubby fatal error: unable to find a suitable template"

Code:
  Installing : dracut-004-303.el6.noarch                                                                                 5/6
  Installing : vzkernel-2.6.32-042stab076.5.x86_64                                                                       6/6
grubby fatal error: unable to find a suitable template
  Verifying  : libdrm-2.4.39-1.el6.x86_64                                                                                1/6
  Verifying  : dracut-004-303.el6.noarch
Please anyone have advice on this? What is the cause and how to fix?

Thank You
