Verified with 3.5.1 vt14 After discussing the required steps to reproduce this scenario with Maor I ran the following scenario: Positive Flow: --------------- As user 'admin': Created VM with 2 block disks Started the VM Created a new user Assigned storageAdmin permissions to the user Logged out as user 'admin' and logged in as the new user From the VM->Disks tab selected both block disks and moved them from the current storage domain to a new domain. The operation was successfull indicating that the user had all relevant permissions. Negative Flow: --------------- As user 'admin': Created VM with 2 block disks Started the VM Created a new user Assigned diskCreator, diskOperator userInstanceManager and VMPoolAdmin permissions to the user Logged out as user 'admin' and logged in as the new user From the VM->Disks tab selected both block disks and attempted to move them from the current storage domain to a new domain.
