oVirt 4.3 is quite old.
Anyway since 4.2 you could put iso files on your ordinary data domains,
where performance access should be acceptable for any host.
In 4.2.x there were some problems when swapping CDs in a running VM with
iso being on block based data domains, but I think this had been fixed in
4.3
You can also put your iso in different data domains and use then the one
that is better for you when you need to install an OS in a VM from iso

Thank you for your help. ISO images uploaded via oVirt Image I/O (Open Virtualization
Manager -> Storage Domain -> Disks -> Uploads) can be used as a CD. The only
significant disadvantage of Storage Domain with the Data function compared to ISO is that
the images are downloaded over the network first to the host with the Engine, and then
transferred to the final host with NFS. This loads the channels, the Engine itself. In the
case of an ISO, the image can be manually uploaded directly to the destination NFS server.
