Hi,
I am trying to do passive profiling of domains in xen. kernel is=A02.6.18-1=
28.1.1.el5xen.I am not getting the domain samples. Below is the oprofiled.l=
og. 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=3D1,2,3,4=
,5=A0/usr/bin/opcontrol: line 1275: echo: write error: Invalid argument/usr=
