I have faced an issue with the installation in one server and which was fixed by creating a simlink

 /etc/grub.conf -> ../boot/grub/grub.conf
 ========

3. No display for   lveinfo

    [~]# lveinfo -d --period=1d -o total_mem_faults
    Error while reading lve_version from database

 Solution :
     service lvestats stop
    mv /var/lve/lveinfo.db /var/lve/lveinfo.db.back
    service lvestats start
