“None of the pre-built vmmon modules for VMware Server is suitable for your
running kernel. Do you want this program to try to build the vmmon module for
your system (you need to have a C compiler installed on your system)? [yes] yes
Using compiler “/usr/bin/gcc”. Use environment variable CC to override.
Your kernel was built with “gcc” version “4.3.1”, while you are trying to use
“/usr/bin/gcc” version “4.3”. This configuration is not recommended and VMware
Server may crash if you’ll continue. Please try to use exactly same compiler as
one used for building your kernel. Do you want to go with compiler
“/usr/bin/gcc” version “4.3” anyway? [no] yes

Iotop is a Python program with a top like UI used to show of behalf of which process is the I/O going on. It requires Python ≥ 2.5 and a Linux kernel ≥ 2.6.20.”
For Suse 11
Simply type “yum install iotop”.
