Hi Guys,
I am building LFS for the first time and am just not able to make the

It's a virtual machine running CentOS and LFS is installed on /dev/sdb
That's not obvious from the above.
You need to use a initrd for booting into a LVM partition. See BLFS.
Plain LFS does not support LVM.
I would tar up the entire LFS build and save to real host. Then reinstall
Centos without LVM. Recreate/format the partition and untar LFS back to the new
partition.
