Subject: strange cpu number from xm info
Date: Fri, 06 Apr 2012 08:45:49 -0400 [thread overview]
Message-ID: <4F7EE57D.4020207@oracle.com> (raw)
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
