Hi, I want to use xenoprof to profile the overhead of the hypervisor. I patched the oprofile-0.9.5 using the patch from xenoprof.sourceforge.net Debian GNU/Linux 5.0 (lenny) Xen-4.0.1 + 2.6.32.25 (linux-2.6-pvops.git) Dom0 My platform is Intel(R) Core(TM) i7 CPU 960 @ 3.20GHz My problems are: In Dom0, after initialization (opcontrol --init), When I start daemon this in Dom0, I got the following error messages : opcontrol --start-daemon --event=CPU_CLK_UNHALTED:1000000 --xen=/boot/xen-syms-4.0.1 Error: counter 0 not available nmi_watchdog using this resource ? Try: [Comments: there is not /dev/oprofile/0 in /dev/oprofile] opcontrol --deinit echo 0 > /proc/sys/kernel/nmi_watchdog [Comments: I do it using this instructions, but it does not work; and I find that the /proc/sys/kernel/nmi_whatchdog is 0 already] My questions are: 1. Couldn''t xenoprof works in Xen 4.0.1 ? 2. Why these error message were output If xenoprof works in Xen 4.0.1 ? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
