Re: [Xen-devel] [XENOPROLIFE] New oprofile patch for XenOProfile

["Ray Bryant" <raybry@xxxxxxxxxxxxxxxxx>]

Renato,

Well, I'd postponed any work with xenoprof until we had a working 3.0.3 
version plus the local patches that we are using (includes the xenoprof 
patches that Tom Woller et al have done).

So, I'm now working with an oprofile 0.9.2 plus your patch 
oprofile-0.9.2-xen.patch from the HP open source website.   The particular 
project we are working on requires us to obtain profiles for the HVM guest 
kernel.   Unfortunately, my first few tries at this have been unsuccessful (I 
get lots of "lost kernel sample" messages in the oprofiled.log and no 
reported samples for the guest kernel.  :-(  ).

So I guess my guestion to you is, do you have access to a VT or AMD V enabled 
platform that you can test stuff on?   (I'd like to find a collegue to work 
with on this problem if at all possible.)   I have dedicated VT and AMD 
platforms for my use, so if you have a VT platorm, we can get stuff to work 
correctly there first and then I can work with Tom et al to get the AMD V 
versions to work.
