xen-U CPU usage accounting

xen-U CPU usage accounting

[tdc]

Hi,

is there some way how to do CPU usage accounting for running domains? I 
know I can watch CPU Time in 'xm list', but from this I cannot (easily) 
see, if the CPU is in current time loaded from 20%, or 90%. Something 
like 'top' or any similiar tool would be nice, IF it can read CPU load 
(RAM usage, I/O accesses, ...) of different domains from within domain-0 
without needing access to xen-U domains directly.
If there is nothing like that, how difficult would be to get this from 
Xen and what skills are needed for that?

Dave
