Re: [Xen-users] understanding xm top

["Tommie McAfee" <tahmmee@xxxxxxxxx>]

 If xm top shows 10% CPU utilization for domain0, it means the CPU utilization in domain0 is 10% of FOUR physcial CPUs. Is this right?

I  don't think the values scale that way percentage wise, because with 4 physical cpu's, xm-top can show CPU(%) to be as high as 400%.  Unlike the native Linux top command where the scale is 0-100%, if you have 4 cpu's and xm top shows 100% it doesn't mean that your using 100% of 4 physical cpu's (all your processing power), but perhaps 1/4 of your 4 CPU's. 

try doing a 'xm top', and type 'v' on the console window, this should give you a per-cpu break down of each domain,

hope that helps,
