Description of problem: It is possible to create multiple HW pools with teh same name in the same place in the tree. How reproducible: Click on the 'default' HW pool, create a new subpool called 'mypool'. Repeat at least once more Expected result: The second and further attempts to create a pool with an existing name inside one pool is rejected.
It also exists in version 0.96.
We already had the validation rule in place, but the way the betternestedset API sets the parent_id the rules were being bypassed. Fixed in the linked patch: https://www.redhat.com/archives/ovirt-devel/2009-May/msg00193.html
