The oprofile patch for xen was turned off when fedora rebased to oprofile-0.9.5 because the patches did not apply cleanly: http://pkgs.fedoraproject.org/gitweb/?p=oprofile.git;a=commit;h=c1c334d9e6052d1c8ae8ab0358bc9558eef1b75e The website, http://xenoprof.sourceforge.net/#download, has a newer oprofile-0.9.5-xen.patch and it apply more cleanly to the oprofile-0.9.3-xen.patch. I put a scratch build through for F14 to try and see if provides the desired xeoprof support. http://koji.fedoraproject.org/koji/taskinfo?taskID=2976532 Could you give one of the RPMs there a try test to see whether it works? The short answer is that the package proposed in comment #1 works -- I was able to use it to passively profile a DomU domain. The long answer is that modifications to the Fedora Linux kernel are also necessary, beyond using Michael Young's 2.6.32.X-series kernel [1]. In addition to Michael's changes (adding Dom0 support), I had to apply Anil Madhavapeddy's "passive profiling on PV Ops kernel" patch [2] *. Once I built and booted the new kernel, I was able to passively profile an experimental DomU kernel by following these steps: 1. opcontrol --reset 2. opcontrol --start-daemon --xen=/boot/xen-syms-4.1.0-rc8 --vmlinux=/usr/lib/debug/lib/modules/2.6.32.34-175.xendom0.fc14.x86_64/vmlinux --passive-domains=1 --passive-images=/path/to/exp-kernel.elf 3. opcontrol --start 4. Run experiment 5. opcontrol --stop 6. opcontrol --shutdown [1] http://fedoraproject.org/wiki/Features/XenPvopsDom0 [2] https://github.com/avsm/linux-2.6.32-xen-oprofile/commit/4df4780e638d14249b7aa4005511218a9183c324.patch * To build the kernel, I: 1. Based my work on Michael Young's 2.6.32.34-175.xendom0.fc14.x86_64. 2. Modified config-generic to contain CONFIG_IGBVF=n, because this module failed to compile with GCC 4.6. 3. Added "%define with_perf 0" and "with_perftool 0" because perf would not compile with GCC 4.6. 4. Ran "depmod" and "dracut /boot/initramfs-VER.img VER" by hand. oprofile-0.9.6-20.fc13 has been submitted as an update for Fedora 13. https://admin.fedoraproject.org/updates/oprofile-0.9.6-20.fc13 oprofile-0.9.6-20.fc14 has been submitted as an update for Fedora 14. https://admin.fedoraproject.org/updates/oprofile-0.9.6-20.fc14 oprofile-0.9.6-20.fc15 has been submitted as an update for Fedora 15. https://admin.fedoraproject.org/updates/oprofile-0.9.6-20.fc15 Package oprofile-0.9.6-20.fc14: * should fix your issue, * was pushed to the Fedora 14 testing repository, * should be available at your local mirror within two days.
