I have a suspicion that the user logged into user portal which has this error does not have permissions on the storage domain on which the template from which the VM is being created from has the disks. Could you please set the user permissions properly and check again?

I was trying to simulate this situation and I can not get to a state where it actually fails on NPE. It either shows: "There is no Cluster on which you can create a VM. Please check Data Center status and Cluster permissions." or it lets me to submit the dialog and results in "you dont have enough permissions to perform this action". Could you please provide the exact configuration of permissions which caused this to happen? Thank you
ok, finally succeeded to simulate. This is what is needed: - have 2 data storage domains, A and B - give the following permissions to the user: disk creator on domain A, the UsertemplatebasedVM on Cluster and VnicProfileUser on Networks - create a template with disk on storage B (e.g. the one where the user has no permissions on) - from user portal try to create a VM based on this template - observe the exception
