Hello Xen Users,
I am using oprofile-0.9.2 along with Xen-unstable which has inbuilt
support for Xenoprof and Oprofile. I have everything installed fine
(i.e. Oprofile.ko is at the right place) but still I am having the
following problem.
When I try to use oprofile with the Host OS, I get the following error:
opcontrol --xen=/boot/xen-syms-3.0-unstable
/usr/local/bin/opcontrol: line 1490: check_valid_xen: command not found
When I use oprofile on a guest OS, I get the following error:
opcontrol --vmlinux=/boot/vmlinux-syms-2.6.16.13-xen
/usr/local/bin/opcontrol: line 1490: check_valid_xen: command not found
It seems that opcontrol is not able to find a script called
“check_valid_xen”. Does anyone has any suggestions.
Thanks,
Nikhil
I looked through opcontrol for oprofile-0.9.2 and didn't see a check_valid_xen
in the script. The stock OProfile 0.9.2 has support for active profiling.
However, It doesn't have the newer patch that includes support for passive
domain profiling.
Is this a stock version of OProfile 0.9.2? I suspect that a patch being used to
update the xen support might not be quite right. The newer xenoprof patch for
oprofile has a check_valid_xen() in opcontrol.
Earlier in the week I applied both the old and new versions of the xenoprof
patch to oprofile-0.9.1 and did a diff of the directories to get an incremental
patch. I haven't tested this on xen so I don't know if it works. I have attached
the patch in question.
