Hello Doron, makes absolutely sense (at least for developers who need to test things a lot ;) >From a practical point of view though it will always a bit different as long as you do not plan major design changes with hosted-engine because of the potential lockout problem (engine-ha and shutdown / reboot, IIRC right now no management other then migration from within ovirt). I know you will have engine more 'manageable' form oVirt itself in the future, but for the following reasons this is not very important for me: Since in a worst case scenario engine is crustal getting tings working again, 'users' (at least me) would tend to use a much simpler/robust setup for engine storage (for instance, plain nfs, gluster 'local' cluster - one replicated brick per host, no dm-multipath ect.). As for the storage of 'production' VMs other points tend to be more crucial (performance, multiple pathes, easy provision and administration ...). My point being, common sense suggests you setup engine storage different from 'production' storage.

Every admin may have his own way of managing the system, and this is perfectly fine. So taking precaution by having a special NFS share makes sense, and would be a good best practice.
