For the initial installation of the operating system in a virtual machine, you need to mount an ISO image that is located in the storage domain of the NFS type (ISO function). If the NFS server is located within a high-speed LAN (one data center), then there are no problems, if you need to connect an image to a remote site (second data center) with slow channels, then difficulties arise.

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
