+.TH LSCPU 1 "JULY 2008" Linux "User Manuals"
+.SH NAME
+lscpu \- CPU architecture information helper
+.SH SYNOPSIS
+.B lscpu [-hp]
+.SH DESCRIPTION
+.B lscpu
+gathers CPU architecture information like number of CPUs, threads,
+cores, sockets, NUMA nodes, information about CPU caches, CPU family,
+model and stepping from sysfs and /proc/cpuinfo, and prints it in
+human-readable format. Alternatively, it can print out in parsable
+format including how different caches are shared by different CPUs,
+which can also be fed to other programs.
+.SH OPTIONS
+.IP -h, --help
+Print a help message.
+.IP -p, --parse
+Print out in parsable instead of printable format.
+.SH BUGS
+The program at the moment does not handle the system installed with
+different types of physical processors.
+.SH AUTHOR
+Cai Qian <qcai@redhat.com>
+.SH AVAILABILITY
+The setarch command is part of the util-linux-ng package and is available from
+ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.

The (untested) patch below introduces a new fields "Hypervisor vendor
ID:" and "Para-Virtualized:" in lscpu(1).
The "Hypervisor vendor ID:" field reports the raw ID, it means it works
for all hypervisors (the same logic like CPU "Vendor ID:").
I think this solution is a good compromise to avoid a new tool.
(Note that lscpu(1) does not support XEN dom0 now. This problem will
be resolved ASAP.)
Comments?

commit 47b6e8b684ad28228c9255fe4237b5a8a1c8c7d3
Author: Cai Qian <qcai@redhat.com>
Date: Sun Aug 10 15:33:51 2008 +0800
lscpu: --sysroot option and stable cache output
This patch added a --sysroot command-line option for testing purpose. It
also sorted cache names, and displayed cache information in a sorted
manner instead of randomly before. In addition, it had some other minor
fixes.
