​Thibuat ... Did you ever get an answer to your problem?  I have
successfully booted an LFS setup like yours on WMVare.  The key info I
needed was from this <http://blog.iandreev.com/?p=729>post.

My more full answer appeared ​on the LFS Support List on July 8th under the
title "Cannot Boot LFS from /dev/sdb1 - Receiving Kernel Panic Error."  I
can send you that full answer as you require, just let me know.

v/r
Keith
