When a host has been created on a VMware compute resource, and you go back to the Edit -> Virtual Machine page for the host (which does not allow editing anymore of course), the settings for Cluster and Network are not correctly shown: always the first item of the popup list is shown, even when the host was created selecting a different item.
This is misleading because other fields are correctly shown.

I know that maybe problems like this are due to limits and bugs in the fog library, like it was for #4324, but the cluster/host is correctly shown in the "VM" tab of the host details page (under the "Hypervisor" label), so it appears there is a way to get it right.
