xenoprofile 0.9.5 opcontrol --start Error: counter 0 not available nmi_watchdog using this resource ?
Hi, all Now I want to profiling xen hypervisor. My platform is xen 4.1.2, ubuntu 12.04. The kernel version is Linux 3.2.0-37-generic #58-Ubuntu SMP Thu Jan 24 15:28:10 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux. I install oprofile 0.9.5+ oprofile-0.9.5-xen.patch. When I want to use it, opcontrol --start, it shows the error message: Error: counter 0 not available nmi_watchdog using this resource ? I have done some commands, opcontrol --deinit echo 0 > /proc/sys/kernel/nmi_watchdog Run again, it still can not work. Anybody met this problem before? Can you give me some advice how to solve this problem? Thank you in advance! _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
