Already asked about one month ago. See thread here:

The last comment by Neil was to provide reasons for this need, as probably
it is not on the roadmap.
But 4.0 version is only at alpha stage so we can influence it, if we push.

Actually already in 2013 it was asked and Itamar at that time wrote that
the team was working on eliminating this limit.. don't know what exactly
was the design limitation from a technical point of view. See thread with
question from (another one... ;-) Jason  here:

and Itamar final comment here:

I'm favorable to have the chance to configure inter-mixed storage, local
and not, especially for testing purposes, but not only, where you have
plenty of storage you cannot dedicate to oVirt VMs now.
The workaround is to have it seen as NFS storage, but it makes sense only
for one-host configuration in my opinion, and it overloads network when it
is not necessary.

Can we vote for it? Do we need to open an RFE?

BTW: I think insipration should also come form what the leaders are doing
(in the positive sense) and in what's new for vSphere 6 here:

you find explicitly inside the "VMware vSphere Fault Tolerance
Enhancements", so in a critical infrastructure point:

There have also been enhancements in how vSphere FT handles storage. It now
creates a complete copy of
the entire virtual machine, resulting in total protection for virtual
machine storage in addition to compute
and memory. It also increases the options for storage by enabling the files
of the primary and secondary
virtual machines to be stored on shared as well as local storage. This
results in increased protection,
reduced risk, and improved flexibility

food to the discussion ;-)
