[Xen-devel] strange cpu number from xm info

[Zhigang Wang <zhigang.x.wang@xxxxxxxxxx>]

Hi,

I see this output from xm info:

# xm info
...

release                : 2.6.32.21-45.6xen
version                : #1 SMP Wed Feb 29 23:42:59 EST 2012
machine                : x86_64
nr_cpus                : 8
nr_nodes               : 1
cores_per_socket       : 4
threads_per_core       : 1
cpu_mhz                : 2826

I thought nr_cpus = nr_nodes * cores_per_socket * threads_per_core

But the above output is not.

Could anyone explain it a little?

Thanks,

Zhigang
