In qemuGetSchedInfo(), libvirt is trying to parse some field of /proc/*/sched. Some fields are floating point numbers and their separator is always a dot. When you change the locale of the system, you can change the mantissa separator (to a comma separator) of floating point numbers and it affects the parser. This commit introduces the virStrToDoubleSafe() to avoid comma as a separator.
