thanks all for your input. Unfortunately it is not working yet and
have the same error:

gave up waiting for root device. Common problems:

- boot args (cat /proc/cmdline)
- check rootdelay (did the system wait for the right device?
- missing modules (cat /proc/modules; ls /dev)
ALERt! /dev/mapper/pv-root does not exist. Dropping to a shell

this is my disk_config file, I am keeping it to the basics now just to
have it installed, later I will add other options.

disk_config     disk1   bootable:1
primary        /boot  500     ext3      rw
primary        -      4096-   -         -

disk_config lvm
vg         pv     disk1.2
pv-swap    swap   2048    swap      rw
pv-root    /      2048    ext3      rw

mmm, then why are all our redhat hosts installed like that out of the
box? Just wondering.
