Cannot open root device "<NULL>"..please append a correct "root=" boot option...

I just finish my third LFS system this time using LFS 6.4 ...as usual I
make all the process in a vmware machine becouse I use it for teching
porpuses, but now at the end I have a kernel panic due to the fact that
it can't mount the root filesystem, the error is the one at subject:
Cannot open root device "<NULL>"..please append a correct "root=" boot
option...here are all the available partitions:
[2.871] 0b00 1048575 sr0 driver: sr
<Kernel panic stuff here>
It seems that is only able to see the "sr" device with the "sr0"
partition witch seems to be the cdrom right?
I'm at chapter 9 (kind of) becouse due to the use of a virtual disk of
course I don't install grub directly from my host PC, intead I boot the
vmware machine with a supergrubdisk and try to boot first manually and
then store the grub config in the virtualdisk from grub console (this
technique works ok for me when I use lfs 6.1 and 6.2)...
To format the virtualdisk at the beggining I boot the vmware machine
with a gparted iso and do the format, the debugfs for that partition
give me this:
debugfs 1.41.3 (12-Oct-2008)
Filesystem features: has_journal resize_inode dir_index filetype
needs_recovery sparse_super large_file
can be that the problem? (those are the "can be" options acording to the
book), or do I need to pass a "...root=sr0" boot option to the
kernel?(witch seems to be the cdrom right?), any other sugestion or
place to look at?
Any help would be apreciated...
