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,
