Hi, friends,
    I'm doing a porting project on XEN2.0.7. I need to get the XENDNODE's physical cpu number, total memory and free memory.
    So far, I'm using "xm info" command to get them.
$ xm info
system                 : Linux
host                   : nvg06b04
release                :
version                : #1 Wed Sep 14 18:55:26 EDT 2005
machine                : i686
cores                  : 1              <==== this is ncpus
hyperthreads_per_core  : 2
cpu_mhz                : 3065
memory                 : 2559           <==== this is total memory
free_memory            : 2405           <==== this is free memory.
    To use the "xm" command, it depends on the "xend" up.
    I want to know if there is better solution, such as reading the data from some file.
    Who can give me a hand? Thank you very much.
