[Users] qemu: too many ide bus during v2v migration

Hi, we're currently migrating over from esxi to ovirt. V2v is pretty smooth, up until I try to migrate a vm with more than 3 SCSI disks. The disks are exported from esxi as IDE and after the disks have been copied over, the process fails with "qemu: Too many IDE bus" Is there a practical way to fix this? Thanks for your help, Stefan
