Hi,
I am trying to do passive profiling of domains in xen. kernel is 2.6.18-128.1.1.el5xen.I am not getting the domain samples. Below is the oprofiled.log. Samples are being lost due to no mapping and no mm. Can anyone suggest what could be the problem?When I start the daemon i get the following error but the daemon starts.opcontrol --start-daemon --passive-domains=1,2,3,4,5 /usr/bin/opcontrol: line 1275: echo: write error: Invalid argument/usr/bin/opcontrol: line 1118: echo: write error: Invalid argumentUsing 2.6+ OProfile kernel interface.Reading module info.Using log file /var/lib/oprofile/samples/oprofiled.logDaemon started.
