CentOS 6 uses grub legacy. Fedora uses grub2. They are completely different, FYI.

In grub legacy that's (hd0,0)

This description isconfusing. You have two / on sda, VolGroup/lv_root and VolGroup-lv2_root. I have no idea what "same as the 1st" means because boot on rootfs is not the same thing as CentOS install #1 which uses a separate /boot on sda1.

This is pointing to /dev/sda2 which is LVM. /boot cannot be on LVM using grub legacy, so in fact you ought to use a single shared /boot since they're the same distro.

The root= entry is completely wrong, you're pointing gruby to an LVM PV rather than to the specific 2nd install root LV.
