I am using xen-unstable with kernel 2.6.16. I enabled the auditd when
compiling kernel. After compile and restart, I did "opcontrol --start"
in DomU. But I got the error message as following:
------------------------------ Using default event: GLOBAL_POWER_EVENTS:100000:1:1:1 Using 2.6+ OProfile kernel interface. Failed to open profile device: Operation not permitted Couldn't start oprofiled. Check the log file "/var/lib/oprofile/oprofiled.log" and kernel syslog -------------------------------------------------Does anyone have similar experience? Is this the right way to profiling the performance in xen systems? Thanks in advance for your help!
