You don't really need to use virt-v2v when the guest already runs on
KVM. The latest oVirt supports direct import of disk images, and
there is also my import script for older versions of oVirt which
didn't have this feature:

Nevertheless I'll answer the rest of these questions because it's an
interesting topic for people importing from other hypervisors ...

Should just work.

On all 3 :-) Are you using `-i disk' input mode? That only supports a
single disk, but you can use `-i libvirtxml' mode instead, and then
you can specify as many input disks as you want:

You always have to tell virt-v2v.

With `-i libvirtxml' it doesn't matter. You specify the XML file, and
that contains references to the disks.

Yup.
