    Bytes to KB conversion should use 1024 instead of 1000

> Currently the feature of memory utilization is not available via API call (listVirtualMachines).
> https://cloudstack.apache.org/api/apidocs-4.5/root_admin/listVirtualMachines.html 
> The listVirtualMachine get its values from the "user_vm_view" table in the database. Currently it shows the CPU utilization of the VM's.
> The only way to find out the memory utilization of VM's running on XenServer, is to run the "xentop" command on the pool master of the cluster.
