Sounds like a great idea to me! I doubt that the hypervisor itself is
already ready for kprobes, but I hope that it's not to hard to get
working ...
Peace,

Hi folks
In linux kernel development, there is a debug tool called
dprobe ,which can be used to dynamic insert the probes into the
function of kernel source code and find what's goning on.There is also
a tool called systemtap which is based on dprobe and kernel debug
info.
Using the kprobes infrastructure, SystemTap is being developed to
dynamically instrument the kernel and user applications.
In this way,we can diagnose complex problems without multiple rebuilds
and reboots.
Can xen use this kind of tools for xen tracing and debugging ? As we
know ,the capability of performace tracing tools (xenoprof)for xen is
limited comparing with dprobe and systemtap.Dose anyone have any good
idea about this ?
My idea is we cab make use of dprobe and systemtap to build a more
powerful and covenient tool for xen performance tracing and
debugging.
