I thought about it, but I don't like that way of proceeding, sort of out of band...

Also, it was one time job so I decided to proceed with direct upload of the disk file and then create a VM on oVirt and attach it.

I would prefer to be able to streamline run virt-v2v from a Fedora system, but it seems it is difficult to compile necessary bits perhaps...

Thanks anyway,

Gianluca
