Discovering the real number of CPUs in the host server from inside of a VZ container
/* numcpu.c code is a part of FFMPEG source (libavutil/) ;)
You can play with the definitions in compilation time. Very interesting.
[root@host:~# grep -c processor /proc/cpuinfo
24
[root@build /]# grep -c processor /proc/cpuinfo
1
We have one openvz container with 1 CPU in one server with 24 cpus (cores: 2x cpu 6xcore 2x ht):
