[one-users] onehost shows wrong memory info [Xen Node]

[knawnd at gmail.com]

I don't know if it's a ON bug.
But 'onehost list' gives me for FMEM the same as 'xentop' for "free" 
(converted to MB) and 'xm info" for  "free_memory". But 'free -m' shows 
much less because of memory caching I guess.
I am using xen 3.4.3 on CentOS 5.5 which is available at GITCO repo 
(http://www.gitco.de/repo/). There is even the newest xen 4.0.1 but I 
haven't tried it yet.

Nikolay.
