[Libguestfs] Virt-v2v virtio device limit?

Thanks Rich

Am I right in thinking this is because the virt-v2v process (libguestfs/qemu-kvm) see's the devices as IDE's as opposed to virtio and is therefore subject to the restricted 4x IDE device limit of old?
Or at least , that's how I'm interpreting the DEBUG output.

BTW - virt-v2v is a cracking tool.  We've so far successfully migrated over 120 RHEL KVM and Xen VM's to RHEV.    Without it, RHEV would not have been an option for us.

Thanks again

The published version of virt-v2v can only handle either 2 or 3 guest hard drives.

The version under development will support many more (at least 250).
