Thank you to Alex, Jakub (you were right, an NFS export domain is OK 
with an iSCSI data center), and René.

- On a separate server, I created a NFS shared space.
- On oVirt web gui, I created a new export domain, plugged on the NFS space.
- I activated it, linked it to my iSCSI data center.
- On the oVirt manager, I installed virt-v2v and its numerous 
dependencies. Seemless.
- Converting a domain using René's advices went all right (thank you).
- Importing into oVirt was also OK.
All those actions were related to linux VMs.

Now, the problem comes with migrating windows vmachines.
I read here at 3.3.1.2 :
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Enterprise_Virtualization/3.1/html/V2V_Guide/sect-RHEV_Converting_a_Virtual_Machine.html#sect-Preparing_to_Convert_a_Virtual_Machine

that I had to install three things, more or less optional :
- virtio-win (this one seems mandatory, as I'm getting the error :
virt-v2v: blah blah blah missing : 
/usr/share/virtio-win/drivers/i386/WinXP or whatever windows OS - I 
tried many)
- libguestfs-winsupport (I don't know whether it is mandatory, as I'm 
hitting the bug above.It seems important as it seems related to the file 
system, so quite useful)
- Guest Tools ISO (this one seems to be similar to VmWare tools, if I 
understood it well), so I don't know if it's an improvement only, 
neither where to find it for oVirt and Fedora.
