OProfile and Xen

[W. Michael Petullo]

Is anyone using OProfile with Xen? I am especially interested in the
passive profiling of Xen DomU domains.

I've attached a Xen patch against the Fedora oprofile package to a
report in Bugzilla, #693596. But, even with this patch I am getting
mixed results.

To follow up on my original question, I was able to make some progress
and am now able to passively profile DomU.

if you are interested. There was also some discussion on the xen-devel
mailing list with the subject of "Questions about OProfile."
