Question
I got a virtual machine running Ubuntu 12.04 with linux kernel 3.2.0-31. When I try to run the sudo perf top
command, which can profile the entire system's processes and gather their information, none of the information shows up. But other commands runs fine, like perf stat ls
that collects all performance info running ls command.
So I am wondering : is that because perf top
command does not support virtual machine? Any ideas?
Solution
is this a guest on vmware. Then it will not work.
