I tried to use same pvops kernel(jeremy's) for both dom0 and domU,= and dullor's patch.
 
But, it does not work well.
 
dom0# opcontrol --start-daemon --event=3DL2_RQSTS:100000 --xen=3D/boot= /xen-syms-3.4.2 --vmlinux=3D/boot/vmlinux-2.6.31.6-xen-xenoprof --active-do= mains=3D1
Using 2.6+ OProfile kernel interface.
Reading module info.<= br> Using log file /var/lib/oprofile/samples/oprofiled.log
Daemon started.
 
dom0 seems to be good. I think,,
 
and domU command
 
domU# opcontrol --start --event=3DL2_RQSTS:100000 --xen=3D/boot/xen-sy= ms-3.4.2 --vmlinux=3D/boot/vmlinux-2.6.31.6-domU-xenoprof
/usr/local/bi= n/opcontrol: line 367: timer: command not found
You cannot specify any p= erformance counter events
because OProfile is in timer mode.
 
And. Some tricky output..
 
dom0#>cat /dev/oprofile/cpu_type
i386/core
 
domU#>cat /dev/oprofile/cpu_type
timer
 
I would appreciate your response....:)

To run xenoprof in active mode you need xenoprof support both = in dom0 and in domU. Try using the the pvops kernel with Dullor's xenop= rof patch in domU too. This should solve your problem...

Subject: [Xen-devel] Is it possible that xenoprof a= ctive domain profiling using pvops jeremy's kernel

my system configuration
 
xen 3.4.2, oprofile 0.9.5( xenoprof patched ), dom0( jeremy's pvop= s kernel 2.6.31.6 - patched dullor's xenoprof patch ), domU( = vanilla kernel 2.6.32 with paravirt enabled ), distribution( ubuntu 9.10 )<= /div>
 
In passive mode, xenoprof seems to work well, opreport showed good inf= ormation.
but, in active mode, it seems not to be done correctly.
 
my command is strictly followed by xenoprof tutorial doc.
 
<dom0>
opcontrol --start-daemon --event=3DL2_RQSTS:100000 --x= en=3D/boot/xen-syms-3.4.2 --vmlinux=3D/boot/vmlinux-2.6.31.6-xen-xenoprof -= -active-domains=3D7
 
<domU>
opcontrol --start --event=3DL2_RQSTS:100000 --xen=3D/b= oot/xen-syms-3.4.2 --vmlinux=3D/boot/vmlinux-2.6.32-domU
In domU, opcontrol was break showing "cannot find timer command??= "
 
I think that domU kernel also should be patched. Is it right?? dullor&= #39;s patch available on vanilla kernel?? I had tried to patch the dullor&#= 39;s patch to vanilla kernel 2.6.31.6 with 2 conflict message.(mmu.c, xen-o= ps.h)
 
is there anyone who succeed in running xenoprof in active mo= de using jeremy's pvops 2.6.31.6 dom0 ??
