Crystal clear!
thank youuuu..!!
Though another Q if possible..
i've done the following:
yum install kernel-pae
vim /etc/grub.conf
#outputs the following:
# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,0)
# kernel /vmlinuz-version ro root=/dev/VolGroup00/LogVol00
# initrd /initrd-version.img
#boot=/dev/sda

kernel /vmlinuz-2.6.18-92.el5 ro root=/dev/VolGroup00/LogVol00 rhgb quiet
initrd /initrd-2.6.18-92.el5.img
After booting, the system hangs on:
"Memory for crash kernel (0x0 to 0x0) notwithin permissible range" for about 2 to 4 minutes.
and then continue booting with the following marked as failed:
1. Mounting HGFS shared
2. VM communication interface
3. VM communication interface socket family
4. blocking file system
5. Virtual printing daemon
Are there related errors to PAE itself, or is it just that VM tools do not support PAE kernel?
thanks

PAE allows a 32 bits host to see more than 4GB of ram. but each process
is still limited to ~3gb. To dive a bit more into technical details,
PAE is like EMS in DOS time. In EMS, you saw the whole ram, but
couldn't allocate more than 64KB per process. With PAE, the same, with
a limit of 4GB-OS stuff per process, so it gives something like 3GB.
Hope I'm clear.
