[Xen-devel] Passive domain profiling support on Xen 4.2.1 or XCP 1.6

[Ryan Jay <developure@xxxxxxxxx>]

Hi all,

I am trying to do Xen / Kernel profiling.
So I tried passive domain profile with oprofile tool in Dom0 as below.

* Environment 1
 + i7-2600 CPU
 + XCP 1.6 Base ISO
 + CentOS 6.3 Guest (HVM,PV)

* Environment 2
 + i7-2600 CPU
 + Xen hypervisor 4.2.1
 + Konrad's passive domain profiling patch applied Dom0 Kernel ( 2.6.32 jeremy branch & 3.2.44 mainline kernel)
 + CentOS 6.3 Guest (HVM,PV)
 
* Commands on XCP or  Dom0 console
 1. # opcontrol --start-daemon --xen=/env/xen-syms --vmlinux=/env/vmlinux-dom0  --passive-domains=1,2 --passive-images=/env/vmlinux-centos63hvm,/env/vmlinux-centos63pv
 2. # opcontrol --start
 3. Run experiment to be profiled on HVM,PV Guest
 4. # opcontrol --stop
 5. # opcontrol --shtudown
 6. # opreport -l
 
* Result of Environments (1 and 2 )
 + Profile report data of dom0-xen, dom0-kernel, PV Guest-xen, PV Guest-kernel, HVM Guest-xen shows up.
 + Profile report data of HVM Guest-kernel doesn't shows up.

* Question
  How can I get profile report data of HVM guest kernel as a result of passive domain profiling ?
 
 Regards,
