recently i just encountered a trouble when trying to deploy a vm from a template.
i must to use the AD domain user account(which has limited permission) to perform this task and deploy the VM in the vsandatastore,
however, in the stage of "select storage" the compatibility section only shows "validating" and never stop.
The process hung at "validating" the vsanDatastore forever and prevent this deploy task from finishing, as shown in figure.
the template was created by the highest administrator right in the vsanDatastore but i guess this is not the point??
is it due to the permission problem on domain user?
-->Doest this happen with one particular OVF or all OVF.
-->Have you tried deploying from webclient and HTML 5 as well ? if not please try
