since there are multiple permissions among the differnet roles, maybe 
worth specifying the actual permissions (actiongroups), rather than just 
the roles?

I'm not sure above two lines are intuitive to manage (a network admin 
can manipulate a cluster, but the cluster admin can't change networks in 
the cluster? this means you must give network permissions, at DC level, 
so you can't limit an admin to network attach/detach to a specific cluster.

again, roles are just default roles, please specify the actual 
permission (actiongroup)

or attached to user VMs.
and need to handle case of network attached to template but user has no 
permission to that network?
