[Xen-devel] xenoprof samples lost due to no mapping
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.
