[Xen-devel] [PATCH] xm --version

[aq <aquynh@xxxxxxxxx>]

This patch adds to xm a long-missing function: showing xen version and
few extra information (thanks go to Keir and Mark for some
suggestions). Here is the ouput of "xm info" after applying the patch
(against -unstable ChangeSet@xxxxxx):

---
#xm info
system                 : Linux
host                   : ubuntu
xen_release            : 3.0-devel
xen_compile_by         : root@localdomain
xen_compiler           : gcc version 3.3.5 (Debian 1:3.3.5-8ubuntu2)
xen_compile_date       : Mon Jun  6 00:30:22 EST 2005
dom0_release           : 2.6.11.10-xen0
dom0_version           : #3 Mon Jun 6 00:32:05 EST 2005
machine                : i686
cores                  : 1
hyperthreads_per_core  : 1
cpu_mhz                : 1094
memory                 : 511
free_memory            : 122
----

You get the point. And here is what the patch does:

- extend xen_version hypercall. the new hypercall keeps the old
behavior if executing it with 0 as its parameter. But if give it the
address of version_op_t structure (see version.h in the patch), it
returns extra stuffs like xen_extraversion, compile date, compiler,
etc...
- libxc now has a new function to get xen version (and stuffs): 
xc_xen_version()
- extend python wrapper for xc_xen_version() and use it in XendNode.py
to get xen version and stuffs.

Any comment?
