Can you look again?
Libvirt should not be adding virtio-scsi devices to the VM without
putting them in the XML as well. If you did not have it in the XML when
you defined the domain and it got auto-added because there was a SCSI
disk with no controller, the controller should still show up in the
output of virsh dumpxml / virsh edit:
<controller type='scsi' index='0' model='virtio-scsi'>
<address type='pci' domain='0x0000' bus='0x03'
slot='0x00' function='0x0'/>
</controller>

there is no scsi in the xml, if I define one, will it show up as an additional or will
change the existing one?
