Hi:
I want to use xenoprof (patched oprofile-0.9.5) to profile VM (both HVM
and PV) apps and kernel performance based on passive domains. My platform
is as follows:
CPU:Intel(R) Xeon(R) CPU E5620 @ 2.40GHz
Hypervosir: Xen 4.1.2
Dom0 kernel: linux 2.6.38.2
I am not sure whether xenoprof can work on this platform.
* As soon as I start xenoprof in passive domain mode, the VM can't run
workload immediately (The VM doesn't crash. If I ping the VM from other
machine, the response time is really high ). I can't input any commands
through the console prompt. *

Do you have the patches applied to the kernel to use oprofile?

The Xeon E5620 processor has model number 0x2c (Westmere class), neither
the Xen or the latest upstream Linux kernel have oprofile support for
this processor.

I have already modified the corresponding code you provide. I add "case 44
(or 0x2c)" before the statement
"*cpu_type<http://lxr.linux.no/linux+*/arch/x86/oprofile/+code=cpu_type>=
"i386/core_i7";". Is it enough to make xenoprof work? Thank you!

I can use active domains to profile the PVM virtual machines. And I can get
some reasonable data. But *As soon as I start xenoprof in passive domain
mode, the VM can't run workload immediately (The VM doesn't crash. If I
ping the VM from other machine, the response time is really high ). I can't
input any commands through the console prompt. *

My dom0 kernel is 2.6.38.2 and I use the xen-patches-2.6.38-2.tar.bz2. (
http://code.google.com/p/gentoo-xen-kernel/downloads/detail?name=xen-patches-2.6.38-2.tar.bz2&can=2&q=
)
