Oprofile collected no samples

Hi,

I am having trouble with CodeAnalyst:

 

CodeAnalyst Warning

Oprofile collected no samples
Suggestion:
-Check the profiling duration
-Check number of counts for events
-Check "start delay period" and "start with the profiling paused" options

 

I am running Ubuntu on VmWare. Any ideas?

Thanks, Levent
