This is interesting. We have a code for getting this info on FreeBSD, but for
some reason it's not working on your system:
src/nodeinfo.c=1041=int nodeGetInfo(virNodeInfoPtr nodeinfo)
--
src/nodeinfo.c-1083- unsigned long cpu_freq;
src/nodeinfo.c-1084- size_t cpu_freq_len = sizeof(cpu_freq);
src/nodeinfo.c-1085-
src/nodeinfo.c-1086-# ifdef __FreeBSD__
src/nodeinfo.c-1087- if (sysctlbyname("dev.cpu.0.freq", &cpu_freq,
&cpu_freq_len, NULL, 0) < 0) {
src/nodeinfo.c:1088: virReportSystemError(errno, "%s", _("cannot obtain
CPU freq"));
src/nodeinfo.c-1089- return -1;
src/nodeinfo.c-1090- }
src/nodeinfo.c-1091-
src/nodeinfo.c-1092- nodeinfo->mhz = cpu_freq;
src/nodeinfo.c-1093-# else
src/nodeinfo.c-1094- if (sysctlbyname("hw.cpufrequency", &cpu_freq,
&cpu_freq_len, NULL, 0) < 0) {
src/nodeinfo.c:1095: virReportSystemError(errno, "%s", _("cannot obtain
CPU freq"));
src/nodeinfo.c-1096- return -1;
src/nodeinfo.c-1097- }
src/nodeinfo.c-1098-
src/nodeinfo.c-1099- nodeinfo->mhz = cpu_freq / 1000000;
src/nodeinfo.c-1100-# endif
I guess the sysctlbyname() call on te line 1087 failed, but I'm not sure why.
Maybe the name is version dependent?
