> CloudStack reports incorrect CPU & RAM usage values for hosts in Basic zone.
> CPU usage is reported about 90%, when "top", XenCenter and other tools report that actual
usage is about 1%.
> The "command=listCapacity&zoneid=1&type=1" returns something like "<percentused>90.49</percentused>".
> The only way I found to get rid of this, is to:
> * place the host into Maintenance mode,
> * remove it from its Cluster,
> * add the host again.
> After this procedure, correct values are reported.
> Interesting that in my practice it happens thrice for hosts in Basic zone, and never
- for hosts in Advanced.
