You might manage to write a vdsm hook to do this, no idea how hard
this can be. See e.g.:
https://www.ovirt.org/develop/developer-guide/vdsm/hooks-catalogue/
https://www.ovirt.org/develop/developer-guide/vdsm/hook/vmdisk/
Latter adds a virtio disk, you might try to write something based on it.

Neither are possible. Does the Fedora have an iSCSI initiator support
perhaps? You can expose those disk via different VMs to that VM - but still
it might look different to the OS.
(We don't even support such an old OS - but if it works, great).
You might try to use a newer kernel. It seems like Fedora 9 or 10 started
supporting virtio, so you can try their kernel.
No idea if it will work, and what might break. Try first on a test VM.
