This is how it currently works.

This is because the hosted_storage domain can't be used as the "master
storage domain", and such as master is required for many things.

Did this solve all your problems? If not, please:
1. Try again with 3.6.3, which should be out in a few days, or the latest
RC [1].
2. If you still have problems, please state versions of OSes and whatever
other relevant tools, and post (links to) full logs of both the host and
the engine:
/var/log/ovirt*
/var/log/vdsm*
