Yes.
Further digging into the code in the net/ directory, there are more
functions that should be traced/probed - e.g. a lot of the net_socket*
routines.
Given that SystemTap,

Thanks, that's what I thought too.

Hi Rayson,
For the KVM kernel module Linux trace events are already used. For
example, see arch/x86/kvm/trace.h and check out
/sys/kernel/debug/tracing/events/kvm/*. There is a set of useful
static trace points for vm_exit/vm_enter,

Hi all,
I am a developer of Systemtap. I am looking into tracing KVM (the kernel
part and QEMU) and also the KVM guests with Systemtap. I googled and
found references to Xenprobes and xdt+dtrace, and I was wondering if
someone is working on the dynamic tracing interface for KVM?
