[virt-tools-list] [PATCH v2] virt-top : stream mode.

[KAMEZAWA Hiroyuki]

I'm sorry my previous patch includes some mess and somethin broken.
I rebuild patches onto virt-top-1.0.5 and I think this version is clean.

This patch adds --stream mode for virt-top. When I use vir-top, I sometimes
want to do 
 # virt-top | grep| awk ....
but good mode for this method is not provided. --csv /dev/stdout requires
some careful script which parse csv file and not suitable to see the result
in console directly.

With --stream mode, all outputs goes to stdout, as,
==
virt-top time  13:14:52 Host bluextal x86_64 8/8CPU 3165MHz 24033MB
   ID S RDBY WRBY RXBY TXBY %CPU %MEM   TIME    NAME
    7 R    0    0    0    0  0.4 17.0  16:11.27 Guest01
    8 R    0    0    0    0  0.6 34.0  33:15.62 RHEL6
==

This mode use one-line-per-one-domain, classical style of output as
top -b.

Thanks,
