Hello, xen = users,

I installed XenServer-v3.2.0 on = my Dell PowerEdge 6850 and compiled dom0 kernel with oprofile support = enabled.

I also made a guest VM = –Centos 4.5 with kernel 2.6.9 through “p2v”. And then I newly = compiled the guest VM kernel

with “oprofile support = enabled” using the following source RPM for xenoprof test

kernel-2.6.9-42.0.8.EL.xs3.2.0.284.src.rpm=

During compiling the kernel, the = xen.patch file doesn’t activate the “profiling support” when X86_XEN = is enabled. So I fixed it

to enable “profiling = support” even though it sets X86_XEN.

-----

Just remove the “!” = on the following code

>> = xen.patch

arch/i386/Kconfig

274 = +if !X86_XEN

275 = source "arch/i386/oprofile/Kconfig"

276 = +endif

----

And then I try to use oprofile = on both dom0 kernel and domU kernel. But when I start a profiling daemon on the =

domU kernel with the event = “GLOBAL_POWER_EVENT”, the messages said,

You cannot specify any = performance counter events

because OProfile is in timer = mode.

How can I get solved this = problem? Is there anybody who let me know how to enter the event counter mode =

instead of timer mode?? =

Thank = you!!
