Hello,
I and my mentor, Mr. Eugene Teo (cc-ed in this mail) have been
discussing some interesting project ideas involving systemtap. I have
worked with Systemtap in this year's Google Summer of Code on the
bootlimn project[1] for Fedora.
Interested in working further with systemtap, he gave me this suggestion
about instrumenting XEN and KVM. We felt that getting information
about the guest from the host might be an interesting project.
We wanted to know if this idea would be feasible and useful for the
community. I would be grateful for any suggestions/feedback related to
this.
Regards
Satya

Hi satya,
I'm also interested in (early) boot-time systemtap tracing and
virtualization support.
As far as I know, the nearest project is the VESPER project, which
is the framework to gather the state of guest kernel. They will
support systemtap on their framework.
Vesper:
http://vesper.sourceforge.net/
And also, the Xenprobe which is a prototype of guest probing
infrastructure like kprobes, has been published. (I'm not sure
he opened his code.)
Xenprobe:

Thank you,

By that, I mean writing useful tapsets that one can use to write
meaningful scripts to instrument or gather information from the
running guest.
Thanks, Eugene

I think VESPER project members might be interested in those
scripts, even if they are focusing on high-availability.
