Hi All,
I'm not sure who this falls to, so I've included all all parties that I
thought may be relevant.
I'm getting the following error from my guest kernel when running
oprofile within qemu-kvm:

I tried to create a similar setup but can't see which instruction
could trigger the gp. If you have the object files available, could
you send me the obj dump of raw_notifier_chain_register() of the host
setup with something like:
objdump -Sdl kernel/notifier.o
Is there any special in your oprofile setup?

Running oprofile in qemu-kvm guests is not supported, though an gp
should not be triggered by the oprofile driver. Do you see anything in
dmesg of the host when the guest gp triggers?
Same here, could you send me the objdump of nmi_cpu_setup() and
nmi_setup() (guest kernel)?
objdump -Sdl arch/x86/oprofile/nmi_int.o
Thanks,
-Robert

kvm does not virtualize a PMU before Linux 3.3, so oprofile is not
supported. The facilities for identifying the PMU to the guest are very
lacking, so it's hard to make this fail gracefully.
On a Linux 3.3 host, you can provide a PMU to the guest, but only using
latest qemu and providing -cpu host or similar. This only works on
Intel hosts for now.
