> When I reviewed some of recent VMware changes, found that the latest change 
> on HostMO.getVmVncPortsOnHost has introduced a performance impact.
> VMware API is designed to use as less as calls to vCenter with property 
> collectors, we need to use it the right way to avoid individual call to 
> vCenter, especially inside a loop
