I want to use xenoprof on ia64/xen to do some
performance analysis. But xenoprof fails to work.
The following is what I have configured:
Xen
version: changeset: 15044:eabda101b0c5
download oprofile 0.9.2 and
oprofile-0.9.2-xen-r2.patch
is patched in domain0, and also built & installed.
domain0
linux kernel is configured and rebuilt for enabling oprofile:
CONFIG_PROFILING=y
CONFIG_OPROFILE=y
But after the above work, xenoprof still can’t
work correctly
#opcontrol –start
Using default
event: CPU_CYCLES:1000000:0:1:1
Using 2.6+ OProfile
kernel interface.
Running perfmon
child on CPU0.
CREATE_CONTEXT
failed: Device or resource busy
Waiting on CPU0
<hang……>
Does anybody have some suggestions?
Thanks
