> 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
