kvm_exit cannot probe by systemtap on Ubuntu12.10

[Praween Amontamavut]

I used the package of kvm, qemu, systemtap form Ubuntu install package.
I tried to probe the reason of VM_exit.

praween@intern:~/debug/tracing/events/kvm/kvm_exit$ sudo stap -e 'probe kernel.trace("kvm_exit"){println("OH\n"); exit()}'
semantic error: no match while resolving probe point kernel.trace("kvm_exit")
Pass 2: analysis failed. Try again with another '--vp 01' option.

I checked the trace probe points of systemtap. The kvm_exit is not available on systemtap probe points.

I checked that the trace point is available on debugfs.

When I copy the kvm trace point header [trace.h] from kernel image source code to build path of kernel, systemtap can be get all probes point of kvm same in kernel trace point of debugfs.
