dtrace discuss - Dec 2007 - Tracing Linux, via Solaris, on a Mac?

In Bryan''s tech talk, IIRC, he mentioned the fact that some Sun
engineers had used DTrace to trace Linux apps, using Solaris''s
Linux emulation environment.

Assuming I didn''t misunderstand all of this, I''d like to know
if the specifics of all this have been written up anywhere.  My
actual interest goes a couple of steps further.  Might it be
possible to:

  *  Load Parallels (or VMware Fusion, or ...) on an Intel Mac.

  *  Load Solaris under the VM environment.

  *  Start up the Linux emulation environment under Solaris.

  *  Start up some app(s) of interest.

  *  Use the Solaris DTrace to monitor the Linux apps.

and if so, can anyone give me some hints (or better, notes) on
how to do this?

The technical pieces are certainly all there; Adam''s blog entry on the
subject should at least fill in the gaps for you on the Solaris/Linux side:

  http://blogs.sun.com/ahl/entry/dtrace_for_linux

Amusingly, you can also get to Adam''s blog entry by googling
"dtrace linux" +
"I''m feeling lucky"...
