Re: [Xen-devel] Calculating real cpu usage of Xen domains correctly!

Rather than trying to come up with metrics like this, I'd rather have
vm-top show the percentage of a physical CPU that each domain used,
independent of it's allocation.
i.e. total including the idle domain will be #CPUS x 100%.

Right, that's exactly what we want to do. How does one get that information? We thought that xc_domain_get_cpu_usage() would provide that information but it doesn't appear too.
