Hi,
i have reinstalled my hosts with 7.0.1 in a vCenter 7.0.1 and i noticed that it is not possible to configure the hosts "Swap File Location" when the host is in a cluster which has configured that the Swap File Location is on a Datastore specified by the host.
The only way to specify a location on the host is to move the host temporarily out of the cluster.
Looks like "bug" to me.
Kind regards
Stefan
