There is something wrong.

No there isn't. because it's HT, that means that each physical CPU has two 'virtual' CPUs (siblings). hence your two processor machine is detected as four cpus.

Yeah but the 4 CPUs were only detected when I increased the number of CPUs in the kernel to 8. When it was 4, it wasn't detecting 4 virtual CPUs.


Why the number should be increased to 8 to get it working right?
