If you need any more information please let me know. The smoketest script does a \
whole bunch of network related operations. I have also used a standard povray \
benchmark to generae some profiling samples. Nothing works. Am I missing something?

Like the comment says, you can't use performance counters under VMWare.

VMware

OProfile can't work with VMware when using performance counter interface.
A workaround is to use RTC mode (2.4 kernel) or timer interrupt mode (2.6
kernel)
