[Lustre-discuss] Test setup configuration

I have setup luster as following 

MGS/MDT/ost0/client- running on a x86_64 server with RHEL5.2
kaveri.hpc.com 2.6.18-53.1.14.el5_lustre.1.6.5smp

OST1/client - running on x86_64 server with RHEL5.2
gangotri 2.6.18-53.1.14.el5_lustre.1.6.5smp

Above setup is seems to be working fine, I have tested it with dd, it shows
throughput as 54.5 MB/s

Now I want to connect another Linux(RHEL4.4) client which is running on as
32 bit VM on ESX 3.5

I have installed following rpm on client

and modified NIS configuration(yp.conf, ypbind), hosts file and appended
modprobe.conf with 

#Networking options, see /sys/module/lnet/parameters NO ../lnet/parameters
options lnet networks=tcp0(eth0)

But when I am trying to mount its giving following error

[root at ganges lustre-client]# mount -t lustre kaveri at tcp0:/spfs /mnt/spfs
mount.lustre: mount kaveri at tcp0:/spfs at /mnt/spfs failed: No such device
Are the lustre modules loaded?
Check /etc/modprobe.conf and /proc/filesystems
Note 'alias lustre llite' should be removed from modprobe.conf

Is there any compatibility issue or any mis-configuration? I m not able to
figure out what is wrong? 

Please comment

Lustre servers (MDS/OSS):
      kernel-lustre-smp // patched server kernel
      lustre-modules // Lustre kernel modules
      lustre // user space tools (server)
      lustre-ldiskfs // ldiskfs
      e2fsprogs // filesystem tools

You can install all those RPMs on the client as well, but it is not 
Lustre clients (assuming you have the matching vendor kernel for the 
lustre-modules installed):
      lustre-client-modules // kernel modules for client
      lustre-client // user space (client)
