Extends VcDynamicData This is the return type for the checkCompatibility method. This object
has a host property and optionally a fault which would
be populated only if that host is not compatible with a given dvsProductSpec.
If the host is compatible then the error property would be unset.
This property contains the faults that makes the host not compatible
with a given DvsProductSpec. For example, a host might not be compatible
because it's an older version of ESX that doesn't support DVS.
