Hello,

I'm facing a problem with `xl list` output - as I'm fetching the output of this command once in a minute, gathering the sum of the last column to calculate CPUs/s usage I'm having a `data jumps` from 352242.2 to 9445321553.2 and then goes back to the previous value.  This `blurs` the average cpu usage of the hypervisor.

Here is an output of `xl info` (common is the xl version 4.8.5) on two of the hypervisors (the first one still has the problem) the second had an kernel update and the odd data collection is gone but it also got less VMs on it - so kernel isn't necessarily the reason.
