Not quite true at the moment unfortunately, Nir.
If you have a block based storage domain you cannot done it because of this bug:


This only an issue when changing CD, starting VM from ISO and provisioning
works.

you are right.
I misunderstood it, because when I reported the problem and during my tests I had broken links in the file system of the host, like I wrote here:
https://bugzilla.redhat.com/show_bug.cgi?id=1588400#c3
and I assumed there was no real lvm mapping between the presumed uploaded iso and a real device...
I have just tried on oVirt 4.2.6.4 to upload a CentOS 6.2 boot iso on an iSCSI based SD and then start a VM with run once and it was indeed able to start.
Thanks.
But so where can I find the device on storage domain that maps to the ISO file I uploaded?
 
The problem still remains, as you noted, when in need to attach CD to running VMs and also in situations where during install you have to swap CD, like reported for Windows and .vfd files inside the same bugzilla here:
https://bugzilla.redhat.com/show_bug.cgi?id=1588400#c9

 
 The bug is scheduled to 4.2.8, hopefully we will have time to fix this.

People wanting this bug to fix soon should vote for it here:

I put my vote there. Thanks
