I have only used my variation of the 2.6.39 OProfile patch to passively profile a PV kernel. Note that most of the work was done previously; all I did was port it to Linux 2.6.39. I have not tried it on a HVM kernel. My latest 2.6.39 patch is at: http://www.flyn.org/patches/linux-xen-passive-oprofile/linux-2.6.39.rc5.git= 5-xen-passive-oprofile.patch.gz --=20 Mike :wq
